Lunar Rover's theory of evolution

February 9th, 2010 by willardbeard1964

In the January 20, 2009, the inauguration of President Barack Obama on a robot astronaut “guide,” with a lunar rover leisurely walk, attracting people's attention. Lunar rover is here, and not accidental. That are everywhere but a distant world, 40 years ago, the United States realized the first manned lunar landing, and now once again become the focus of international competition, but will allow astronauts to the moon light work vehicles, represented by the scientific and technological strength. And other technologies, like lunar rover is continually evolving in the … …
1, convertible car glory days

“Flying into the universe, the vast boundless!” This is the Disneyland of the hero “Buzz Light year” mantra, the invincible hero does not know to conquer space, the number of young people and even adults, ignite their space dreams. However, “Buzz Light year” prototype - “Apollo 11″ Lunar Module pilot Buzz Aldrin 40 years ago, and the commander of the moon with Neil Armstrong, it can not be so scenery . Due to the lack of means of transport, the two “Earth Visitors” can only be wearing 84 kilograms of bulky spacesuits on the surface in the staggered walk, although the moon's surface gravity is only one-sixth of the earth, but this by the 21-layer fabric consisting of a bloated clothes, or walking to their great inconvenience, but carried life-support system can support up to 4 hours. So there will be a historical film, we see the Apollo program astronauts on the moon walk funny ways: either moving cautiously, or “leap” forward. Bulky spacesuit equipment, coupled with scientific investigation and collection of lunar soil and rock samples, these “heavy burden” to the first few groups of the astronauts on board the moon's surface caused by a lot of difficult and dangerous.

See here, smart readers will think, why not take astronauts to the moon cars do. The U.S. space program's “chief designer” and later served as director of Marshall Space Flight Center, von Braun also thought of this as early as the 1950s von Braun, and Hewlett-Packard Erdeng pioneer in the space age, “Crean Weekly “(Collier's Weekly) published a series of” science fiction “article,” Fantasy “from the future on the moon, Mars exploration needed in all kinds of technology (in this series of articles to become Disney's first film is based on space exploration script), including the lunar rover (Lunar Rovering Vehicle).

“Apollo program” using the “Lunar Rover” is a four wheel, self-development and production started in May 1969 by Boeing's contract (a unit of General Motors Delco companies as sub-contractors involved in the development), cost of 3800 million, were created by four. The car length 3 meters wide and 2 meters high 1 meter, size, and today's Volkswagen Beetle car almost. Empty weight of 209 kilograms, plus two astronauts and equipment weighs about 700 kilograms. . Vehicle communication system includes a high-gain antenna used to transmit pictures and data, as well as a low-gain antenna for the transmission of sound and television signals. To the lunar rover to provide electricity to two 36-volt batteries. In the driving seat in the middle have a handle, in theory, said that two astronauts could drive the car, but customarily carried out by a long driving instruction.

Lunar Rover has a separate quarter for each wheel horsepower (200 watt) electric motor and brakes, traveling at the speed of the moon's surface 10 to 12 kilometers per hour. Independent motors drive the wheels to ensure a real-time failure of lunar vehicles will still be able to turn. Redundancy design is NASA's first principle, this design will also reduce the lunar rover to the U-turn radius of 3 meters. The lunar rover can climb 25 degree slopes, as far as 67 km can be opened up, but for security reasons, the scope of activities of astronauts no more than 10 kilometers, so the ball Wan Yiyue car broke down, and they can in life-support system expired walked back to the Lunar Module. The first use of lunar rover is in “Apollo 15″ mission.

Apollo 15 was the original plan and the previous period of the moon the same task, but in September 2, 1970 NASA suddenly announced the cancellation of the Apollo 18 lunar landing program and beyond will be Apollo 15, No. 16-17 from the H type of task (ie in the vicinity of landing sites for limited activities) to J type of task (in the moon's surface to stay longer, and use the lunar rover and other updated equipment to carry out more scientific investigation). The use of lunar rover greatly expanded the scope of activities of astronauts, and thus better scientific results.

July 31, 1971, that is, Apollo 15 landed on the moon the day after the first use of a manned lunar rover. Commander David Scott (David Scott) driving lunar rover and the Lunar Module Pilot James Irwin (James Irwin) went to the Elbow crater 3 km outside the study and collecting samples, and then to another location Hadley Hill visits, and then drove back to the lunar module. The second inspection tour to Hadley Hill, Irwin found the famous “Genesis of the Stone” (Genesis Rock, or called the origin of stone), this piece of anorthosite another piece of stone in the head was found, but then The analysis confirmed that it should be generated early in the solar system formed, and the age at least 40 billion years. Before leaving the moon, Scott has done a free fall time on the surface will be a feather and geological hammer at the same time opening up, because on the surface there is no air resistance, both at the same floor, which is four hundred years ago Galileo has moved from theory to prove. Unexpectedly, bending over to pick up in the Scott plans of the feathers on this time, Irwin stepped on one foot, so that the root “of significance” would permanently stay in the feather on the moon.

Scott and Irwin to stay three days in the lunar surface, extravehicular activity 18 hours 37 minutes to drive the road 27 kilometers and collected about 77 kilograms of lunar rocks. With the lunar rover, the astronauts were so much easier, and Scott even said: “I really want to sit down and play for a while stone, these shiny little stones really are extremely cute.” Apollo No. 15,16,17 scientific investigation completed tasks, including the number of collected lunar rocks, are far more than the previous. All three lunar rover on the moon to stay forever and become the “Moon Museum” part of it. More recently, India's “Chandrayaan-I” satellite and the United States, LCROSS satellites are found in Apollo

Plan to stay in lunar rover activity remains, but also to so-called “moon hoax” rumors have been dashed.

In the last century, the US-Soviet space hegemony in the Soviet Union did not show weakness, and the successful lunar rover in time for the United States prior to the success of two unmanned lunar rover to the Moon, respectively, known as the “lunar rover 1, 2, “(Lunokhod 1,2).

Lunar Rover-1 rides on the “Moon 17″ on at the November 17, 1970 in the rain on the sea surface landing area, this is the first time on Earth to another world of robot remote control. The Zheliang lunar rover like a cylinder shape, a protruding above the lid, car Here are eight wheels, each wheel are also independently controlled. The vehicle equipment includes a cone-shaped antenna, a high-precision directional helical antenna, four television cameras, as well as some used to measure the density of lunar soil and the physical and chemical characteristics of the device. The following is the convex cover solar cells. On the surface of the antenna is responsible for the situation to send to Moscow a five-member team, and they are remote controlled lunar rover next move.

This station lunar rover 2.2 meters long, 1.6 meters wide and weighs 756 kilograms. A total lunar rover on the 1st run 10 for one month (only work on the Moon during the day), until October 4, 1978 it was terminated, the day the Soviet Union launched Sputnik days. It is moving a total of 10 kilometers, returning 20000 pieces of television pictures and more than 200 panoramic pictures. Car load of solar X-ray telescope X-ray band, while the laser is used for the determination of the Earth's distance test.

January 15, 1973, lunar rover 2, from “Moon 21″ carrying landed in Chenghai district. This sets lunar rover slightly heavier than that on the 1st to reach 840 kilograms, length 1.7 meters wide and 1.6 meters high 1.35 meters. It has two-speed mode, 1 km or 2 km per hour. In order to prevent the lunar rover on the moon a long night of super-low temperatures have been nipped, the car carrying the isotope heat source, using the element polonium-breaking decay provide energy to maintain the warmth of lunar rover. However, in June 4 that year came to an end this mission, the Soviets did not disclose the reasons is generally believed that may be due to 5,6 on the moon between the long cold night, leading to failure of lunar rover.

Second, return to the moon era of competition in the luxury car

US-Soviet space hegemony era astronauts on the moon between the two countries place more importance on the political significance of the moon's surface sampling can be achieved has been sufficient. But today the situation has been very different, the moon, the rich fusion of raw materials into the goal pursued by all countries, so “the moon club” re-emergence of all the major countries have joined the ranks of the moon, the United States is more ambitious made not only to the year 2020 “return to the moon,” and to establish a lunar base to achieve a permanent presence on the moon and the moon as a springboard for more to explore the depths of the universe, such as to go to send astronauts to explore Mars.

In the lunar surface is not an easy thing to drive, even if the Apollo program in a few hours of short trips, also need to astronauts in the desert terrain in the simulation of contact a few months to come through a “road test” because the moon's surface the situation is too special. The lunar surface gravity is only one-sixth of the earth, and covered with a layer of soft soil, which hampered the effectiveness of the vehicles of the road. On the rugged surface of the vehicle wheels, the chassis design of the formation of numerous obstacles, cornering, climbing is an unusual thing, the moon above, safety first. One day the moon is equal to one month on the earth, temperature changes of up to 300 degrees, “day” sunshine baked the night cold stones can be damaged by frost, which made the vehicle difficult material requirements. Apollo lunar rovers used in the piano line is to maintain the elasticity of the mesh-type tires.

Lunar base means that more heavy labor, for which NASA specifically designed a “lunar truck” (lunar truck). This vehicle and the Apollo program in the Rover, just as convertible car, the astronauts need to wear spacesuits in order to drive. Truck bluntly, that is used to transport bulk goods, in order to meet the demands of building a lunar base, NASA also plans to add other devices in the vehicle, such as forklifts or cranes. Trucks will have six wheels, each wheel has two tires. This breakthrough in the traditional “six-wheel design” has been running in the Mars Rover has been tested, even if one wheel fails, another five wheels still have superior ability to act. The wheel itself can achieve 360-degree independent rotation, this design gives an unprecedented mobile performance, heavy-duty trucks can be made to any one direction. In order to adapt to different terrain, heavy-duty truck chassis can be reduced or increased, the design of the lifting force up to 2 tons of cargo is not the speed can reach 25 km / hr.

Lunar truck has been located in Houston's Johnson Space Center to design a prototype, and tested on a simulated lunar sites.

NASA also a new product, aimed at the presence of the moon astronaut extravehicular activities, namely, “a small pressurized rover” (Small Pressurized Rover), due to no longer be convertible, a closed compartment make astronauts while driving Such vehicles do not need to wear spacesuits. This roaming vehicles are more than 4 meters length width and weight up to 4 tons, load quite up to take four astronauts in the case of guaranteed 3 days of continuous activity. This means that a pressurized rover is actually a small workstations, the scope of its activities up to 240 km, is not worse than the heavy-duty trucks.

Roaming the car has a small bathroom, equipped with spray nozzles can be sponge brush. Each crew has its own private space, separated by a curtain. However, the only food was dried noodles and other convenience foods, because the car is not the kitchen. In the Arizona desert in the simulated tests, astronaut Gerhard even think that Rover as comfortable as the space shuttle. As the human interface settings, the astronauts could be without decompression or compression device directly into a lunar base or enter the spacesuits that will definitely give the Apollo program astronauts envy.

In addition to the manned lunar rover, NASA is also developing an unmanned moon vehicle, that is able to automatically work in the moon's surface robots, such as ATHLETE. This is also a six-wheel robot, the first-generation prototype is greater than 4 meters in diameter, designers hope that it can be quite extensive areas of fast-rolling, or walking, the ultimate goal is to design a system which could combine with other specialized equipment or load multi-objective system. ATHLETE of the load capacity of about 450 kg, a number of robots that match the results can have a greater transport capacity.

Indian Space Research Organization also issued a remote control unmanned lunar rovers planned for 2013 by the “Chandrayaan-II” carried on the moon's surface landing. The rovers used a Russian design, weight 58 kg, six-wheel-drive, will be the moon's surface near the polar scientific expedition for about a year, its exercise of the speed of 570 kilometers per hour, range of activities up to radius of 150 km.

In fact, not only the United States, Russia, the European Union, Japan, India and other countries put forward their own model of lunar rover, and even many private institutions to get in, such as Google Inc. came up with 20 million U.S. dollars to set up a “Google Lunar X Contest” to encourage non-governmental organizations or companies design their own lunar vehicles, be able to photograph the moon's surface after landing and also the road 500 meters, they get awards. So far have been about 20 participating teams, a variety of imaginative design concepts and models.

4, the future lunar rover

As human return to the moon and begin to build a permanent base, the moon began to immigration, a new generation of lunar vehicles will be available. As the moon without air ordinary vehicles can not be used on the moon, only to the main electric car, or use tools such as rockets. With the construction of a lunar base, “Moon society” grow, will produce a variety of specialized uses lunar rover, and means of transport, compared to today, imagine the future of transportation looks like the moon.

The most lightweight lunar rover should be “the moon motorcycle,” only one person ride. In order to drive safely on the surface, it should have three wheels, as it is exposed to type, the driver must be wearing a spacesuit. This is mainly used for light vehicles at close range and from the moon's surface, or solar power station maintenance purposes.

On the moon rocket single-car, no tires, by the rocket jet, the surface of the month for leap-frogging. As the moon's surface gravity is very small, single-seat vehicle for fast-moving between the two places, or to and from the Moon and the Earth between the orbital space station.

High-performance two-seater multi-purpose small-scale lunar rover that can travel hundreds of kilometers a row, suitable for short-distance travel, there are four mesh-type tires, to fuel cells as power source, replace the cylinder with a way to supplement the fuel.

COMBI lunar rover could take six people, and load 500 kilograms, can travel 180 km a row, it also uses sealed, there are two tracks. In addition it is used to detect, but also can be transported between the various facilities in the universe who do not wear uniforms and small animals.

Moon Trailer trucks and tractor units from the container two parts for the transport of supplies. It is powered by solar cells, fuel cells can also be used simultaneously, so that night will be able to work at double speed in the moon's surface.

Lunar orbit bus also known as “wheel landing capsule” once it left the lunar orbit on a low angle into the moon's surface, in the length of 100 km on the runway at a speed of 500 kilometers, as the same sled glide landing, about 2 minutes after that they can stop a.

Lunar orbit bus, due to a rock hard surface may not be suitable for construction of the subway, then the construction of sturdy materials, the safety of the ground rail transportation will become the main form of mass travel. Lunar orbit the bus is more convenient than the subway quickly, but because to guarantee the safety and cost will be very high.

There is also a medium-sized lunar exploration vehicle equipped with the spotlight of high-performance, high sensitivity digital communications antenna measurements, surveillance cameras and radars, the moon may also be driving a dark night. Such cars tire type, but also as a temporary stop to the use of the moon.Video Converter for Mac

Above the moon vehicles, which are still developed. However, when humans set foot on the moon, establish a base in the above, exploitation of resources on the moon as well as the tourism industry, the building of the moon city, the future of lunar vehicles will appear in front of the people, but also may be updated Yingqi Te car appeared. By that time, humans take on the lunar rover to realize the ideal of roaming the moon.

Eight Classroom Environment Tips

January 25th, 2010 by willardbeard1964

Many early childhood programs continue through the summer, so I hope everyone who worked in July and August enjoyed working at their summer programs!

And now, on to a new and exciting start of the school year! Of course there are always many things to think about in the first weeks of school, but a good place to start is with the classroom environment.

Here are eight things I think are important to consider as we work on our classroom environments:

1. Safety – Remember, safety first, both indoors and outdoors. Use safety checklists and carefully review your classroom space as well as your playground areas to make sure they are safe places for young children to work and play.

2. Supervision – Make sure that you have arranged for proper supervision of your students at all times, both indoors and outdoors. Outdoor playtime needs to be carefully supervised, so remind your teachers that they must stay near the equipment and the children to watch for spills and falls.

3. Space – Take time to review and analyze how you are using your classroom space, how your space can be set up to meet the needs of each child, the group and support the program goals.

4. Materials – Do an inventory of your classroom materials. Check to see that you have enough materials for the whole class to use and a range of materials to meet the needs of all the different areas of the curriculum such as math, literacy, art etc.

5. Aesthetics/Decorations – Try to make your classroom bright and cheery, and be sure include children’s work nicely displayed at children’s eye level. Photos of the children and their families make the environment comforting to young children. Adding plants and pleasant music can also add to the attractiveness of a classroom.

6. Personal space for each child – Arrange a special place for each child in your class. For example, a cubby or a coat hook with a “My Things” box underneath provides a place for the child’s personal items.

7. Diversity – Make sure your materials include dolls, puzzles, pictures and other things that depict people of many cultures and backgrounds.

8. Place for parents – Try to establish a place where parents can receive and share information about the program, their children, and current events at the school. Suggestions include hanging a parent bulletin board, setting up a parent information table, designing a parent resource room or even designating a shelf in the school library as a parent book shelf.

What kinds of things have you done to set up your classroom environment for the new year?We would love to hear from you!

Helping Children Manage Fears

January 17th, 2010 by willardbeard1964

0 to 2  ”HELP! IT'S ALIVE!” by Carla Poole

Nine-month-old Joey is very focused as he carefully puts blocks into the tub. Yet every so often, he peeks up and looks for his teacher. She smiles and says, “I see you putting blocks in the tub!” He chuckles contentedly and continues his explorations. This “touching base,” making sure his special person is nearby and available, gives him the confidence to play and explore.

Tune In to Temperament

Sudden noises, movement, or unfamiliar people often frighten babies. Four-month-old Leah likes to be touched very gently. Baby Tommy loves to be tickled, but will cry with alarm if touched abruptly. Tuning in to a baby's preferred way of interacting will help her develop coping skills.

After 12 months of nurturing experiences with familiar teachers and routines, a baby is more prepared and less easily startled. Now she can anticipate a frightening event. She is starting to make connections between events-even though they might not always be accurate. For example, a stuffed animal is placed precariously on the edge of a shelf. Shaniqua, an alert 1-year-old, watches as the toy falls to the floor. She yells for help. All morning long she stays away from the toy. She most likely thinks the animal has come alive. It behaved in a way that she did not expect because it seemed to move all by itself.

Be a Detective

Teachers often become detectives when trying to understand a child's behavior. Why is Shaniqua so afraid? In this case we know what happened. If we didn't, her fear of a cuddly toy might seem unreasonable. Typically, there is a reason behind a child's behavior. Think about what happened just before the behavior started.

Offer Words for Feelings

You can help the toddler cope with fear and organize her thinking by putting her experience into words. “Shaniqua, you look scared. You did not expect the stuffed doggie to fall off the shelf.” Then you can explain that the doggie has not changed. This way, she gradually develops a more realistic understanding of how objects function.

Respect Coping Mechanisms

Young toddlers learn through sensory experiences. Abstract concepts such as spatial relationships often take a backseat to what the toddler sees, hears, and touches. The noisy gurgling of water swirling down the drain makes her think, If water can go down the drain, so can I!

Fortunately their imaginative thinking also helps toddlers cope with fears. Just as Shaniqua's imagination brought the stuffed doggie to life, it can also bestow special powers on her favorite blanket to soothe her when she is feeling scared.

Provide Gentle Reassurance

After 18 months or so, toddlers understand the permanence of objects and the fact that people who are out of sight still exist. However, this thinking remains easily influenced by unexpected or unusual events. For example, if a 20-month-old watches you cover a toy with a scarf, she knows that it is still there, even though she can't see it. Yet when a toddler sees you put a mask on your face, she is overwhelmed by the change in how you look and thinks you have been replaced by a frightening being!

Fear is a natural part of life, and toddlers need lots of reassurance. The key is to limit their daily stress levels.

What You Can Do

  • Babies are very sensitive to new people. Approach them quietly and slowly.
  • Prepare for events that might be frightening.

3 to 4  ”DON'T GO AWAY!” Susan A. Miller, Ed.D.

Each morning, 3-year-old Eli and his 4-year-old brother, Russell, refuse to get out of bed and get dressed. They tell their mom that they do not want to go to their new school. When they finally arrive at the center, Eli drags his feet and whines, “Don't leave me!” However, after his mother is there a short while, he becomes happily involved with his buddy Paco. The director, Mrs. Burkholder, meets Russell at the door. She holds him closely while they pass the school's bunny mascot in the hall. Fearfully, Russell looks back and forth from the bunny to Mrs. Burkholder, pleading, “Don't let him get me!” Once he reaches his classroom, however, he is all smiles.

Lively Imaginations

It is not at all uncommon for preschoolers to have a variety of fears, such as a fear of ghosts or thunder. These worries are frequently heightened by threes' and fours' vivid imaginations, and preschoolers may have difficulty separating appearances from reality. This often causes them to behave in ways that may seem irrational.

Fear of Separation

At times, it can be difficult for parents and teachers to determine why a child is frightened or what they can do to help relieve his fears. For instance, at first glance, it might appear that Eli and Russell are simply afraid to go to school. However, Eli might actually be feeling the pressure to be a “big boy” in this first school experience, and he may be afraid to take the next step-leaving his familiar home environment. Because he clings to Mom upon arrival, but appears contented after a little while, Eli's fear is probably of being separated from his mother.

Reliving Frightening Experiences

On the other hand, Russell may be frightened by something at school based on a prior event in his life. Russell had a scary experience with the big Easter Bunny at the mall. While many adults think costumed characters and mascots are fun for young children, they rank high on the list of frightening things for preschoolers.

Validation and Reassurance

When parents and teachers acknowledge children's frightened feelings and reassure them with their presence-or “protection,” as in the case of Russell's teacher-they can help alleviate some of children's fears. By showing warmth and concern, yet encouraging independence in appropriate situations, adults can assist preschoolers in dealing with their anxieties.

Anxiety and New Experiences

Four-year-olds often appear to enjoy showing off, and they love to brag about things they can do, such as riding a trike faster than anybody else. They also like to please their friends and teachers. For example, Vanessa quickly climbs to the top of the enclosed cylinder slide. Suddenly, she begins to cry, clings to the ladder, and refuses to slide down. Although she is afraid of disappointing those watching her and not meeting their expectations, the challenge of trying out this new piece of equipment is equally frightening to her due to her fear of heights and enclosed spaces.

Literal Interpretations

Preschoolers are inclined to take the things adults say quite literally. Therefore, it is important that teachers don't frighten them with untruths or threats, such as: “If you don't eat all the carrots on your plate, all the hair on the tippety top of your head will fall out!” Instead, talk with children about what is happening (”You need to eat vegetables to stay healthy”), and encourage them to brainstorm meaningful responses to problems.

What You Can Do

  • Reassure a child. Talk calmly about fears he may have. Let him know everyone has fears-including you!
  • Listen to explanations. Try to understand the fear from the child's view.

5 to 6: “I CAN'T DO IT!” by Ellen Booth Church

Lee started to change right before his teacher and parents' eyes. The happy child who entered kindergarten was now complaining of stomachaches, having trouble sleeping, and saying he did not want to go back to school-ever! What changed? The answer: academics! The class was now being asked to do more and more pencil-and-paper work, and Lee didn't feel he was as good as the others were at drawing and writing. Happily, his teacher and parents realized this quickly, helped Lee feel good about what he could do, and made sure that he had plenty of time to express his learning through play.

Managing Changes

One of the big shifts that happen for children in kindergarten is the awareness of the different developmental (and academic) levels among their classmates. This is the stage of life when they start comparing their work with others. Most children in preschool are still so self-focused that they don't worry about what they are doing in comparison to others. But by kindergarten, children are quite aware of who can already read and write and who is still scribbling. Sadly, these comparisons can turn into worries and even fears. It is essential to catch these at this early age, before they become ingrained in a child's self-concept and his feelings about learning at school.

Working With Academic Pressures

As a teacher, you know to watch for the signs of academic worries and fears. Children may lose enthusiasm for school or for particular activities. Some children may become lethargic or the opposite, highly active. Difficulties listening in a group or paying attention can also be related to children's academic anxieties. Interestingly, children who are afraid or embarrassed about making mistakes can be very critical of others. Physical bullying can also be a response to children's fears about not being “good enough” to keep up.

As you well know, the best remedy is a program that provides activity choices that reflect children's interests and abilities. Mix in a good amount of support for differences, balanced with appropriate challenges, and you have a solid kindergarten program that encourages children to appreciate themselves at their own levels.

Feeling Like a “Big Kid”

In contrast, another aspect of a 5- to 6-year-old's development is the child's desire to appear and feel grown-up. Children at this age like to boast about what they can do and will often accept new challenges, and even take risks, when they are feeling comfortable in a setting. Fives and sixes also like to feel they are in charge and to make their own decisions.

A climate that supports these desires and feelings can work as the perfect antidote to academic fears. Involve children in making classroom decisions, reinforce mature behavior, and celebrate appropriate risk taking-even if the results aren't positive. It is important for 5- and 6-year-olds to learn that everyone, including parents and teachers, makes mistakes. Repeatedly demonstrate for children how a mistake can lead to greater learning and success.

Looking for Balance

Remember, fears are a normal part of development. There are appropriate concerns, such as fear of a barking dog or of crossing a busy road. A child's fears become unhealthy when they limit him from leading a happy, normal life at home and at school. It is our job to help children find a balance between healthy and unhealthy fears and to understand the difference between them. It is wise to be careful around a barking dog or busy traffic, but it is not necessary or even helpful to become fearful and frozen. The same can be said for schoolwork. We want children to respect the work they are asked to do without becoming fearful of completing it.

The kindergarten year is filled with new challenges. We can now begin to prepare children to meet those challenges with confidence and creativity. The emotional and academic support you provide now will offer them valuable tools they can use to handle whatever challenges come their way.

What You Can Do:

  • Observe children closely for signs of academic worries and fears.
  • Offer a multidimensional program that provides activity choices reflecting children's interests and abilities. Some children may need to physically, verbally, or artistically express the work that others are doing in paper-and-pencil tasks.

Babies are born with built-in problem-solving tools called reflexes. Less then an hour after birth, a baby will use her rooting and sucking reflexes to feed. As she grows, many of her automatic responses will be replaced by more voluntary actions.

At 2 months, babies become more alert and eager to explore the world around them. By 4 months, the baby has developed the muscle control and hand-eye coordination to bring toys and other objects to her mouth. The joyful exploration and experimentation that leads to problem-solving has begun.

Looking for Results

By 8 months, babies enjoy playing with toys that produce interesting responses to their actions. Grasping, shaking, and banging toys that make unusual sounds and movements are especially popular. These fun experiences help to lay the groundwork for children's later understanding of cause-and-effect relationships.

Intentional Imitation

Children move to a more purposeful level of problem-solving by their first birthday. No longer limited to what's immediately in front of them, they can now push aside a toy in order to reach another, more interesting one.

One-year-olds also begin to solve problems through observation and imitation. Fourteen-month-old Daisy, for example, is puzzled by her new child-care center's stacking toy. She watches closely as her caregiver removes the top ring from the toy. Daisy then takes off the next ring. When her caregiver replaces the first ring, Daisy again follows her lead and replaces the ring she was holding. Her caregiver smiles and claps, and Daisy laughs with pleasure at having discovered how to use this new toy.

Trying It All Out

Once they reach toddlerhood, children use the “What would happen if …” approach to problem-solving. They experiment with a little bit of everything in their persistent search for a solution.

Eighteen-month-old Emma, for instance, is busy trying to make the mechanical dog move. She shakes it, turns it upside down, pushes the key, and pats the puppy's head. Finally, she turns the key - and the puppy moves!

Recalling Solutions

By age 2, children have begun to use an important new problem-solving tool - memory. Now the toddler can observe, think about the problem, and then later on remember what she saw and imitate it.

When 2-year-old Susie wants to open the drawer in a piece of dollhouse furniture, for example, she no longer shakes and bangs it as she would have a few months ago. Instead, she remembers watching her caregiver open the drawer and uses the same technique.

What You Can Do

Young children have so many problems to solve and so little time! You can help by providing opportunities for open-ended exploration and offering help before children become too frustrated.

Offer babies a variety of intriguing items they can grasp and suck. Exploring new materials sets the stage for later problem-solving skills.

Give babies toys that produce responses to their actions. Toys that make funny noises when they're grasped, shaken, and banged are very popular.

Place interesting toys just out of a 1-year-olds reach. This makes her work to get the toy. However, if she loses interest, bounce the toy and push it a little closer.

Help children find solutions to real-life problems. When a ball rolls behind the shelf, for example, ask the toddler how he thinks he can get the ball. Try out his suggestions, and then share your ideas.

Provide a variety of materials at the water table. Exploring which objects sink or float, how much water containers can hold, and which items absorb water are all great problem-solving experiences.

Communicating Through Writing

January 8th, 2010 by willardbeard1964

You can visit professional parental knowledge in HappyTree Early Childhood Development Center.

For many children, the beginnings of literacy appear in activities such as pretend play, drawing, conversations about signs in their environment, and writing. They frequently mix writing and drawing (sometimes we call it anting), creating a “mixed medium” that combines graphic forms, letters, and words. These earliest attempts at writing are especially delightful and visible to the eye because they involve making something-usually marks on paper.

Early Experimentations

In these early experiments, children begin to realize that writing can be useful in their social relationships. They can use writing to make requests, to define and label their world, to express feelings of friendship and anger, and to get attention. Children will create signs, as exemplified by 4-year-old Catherine who writes on her door “Don't Boter Me” to assert her feelings toward a sibling and show her frustration. When children like Catherine play with the activity of writing and the role of writer, they begin to learn how to form letters and write words, often inventing their own spellings along the way.

How It Happens

It turns out that there are developmental patterns in children's early mastery of writing, although there is considerable individual variation among children. Although there are no reliable developmental milestones tied to age, as there are with physical development, you can expect children to begin to master writing through several phases. For example, at around 18 months, children become fascinated with pencils and paper and will begin to scribble. Early scribbles often look rather disorganized. However, children are actually exploring the sheer effort it takes to control and coordinate these wonderful writing implements. As they gain better control of their fine motor coordination, you'll begin to see recognizable shapes and patterns-lines, dots, circles-as drawings and writings begin to emerge. From these scribbles, children begin to incorporate features of writing. They'll notice the visual features of letters, and soon they will generate a variety of letters. Marie clay, a pioneer in studying children's early writing, called this point in children's development me sign concept. Children may understand that marks on paper have some kind of meaning without necessarily understanding what that meaning is. For example, 4-year-old Nathan might show you many, many letters, and then ask, “What did I write?”

Moving On

Between the ages of 4 and 7, children may become more and more intrigued with the idea of communicating through writing. They'll begin to “invent” spellings of words, like elpt for elephant, or tkt for ticket. Sometimes, they'll even write a phrase, such as I lv u (I love you). With these efforts to communicate, children will construct their own spelling rules. As they write their own stories, children may be trying to recreate the kind of imaginative experience they know from pretend play and from being read to. This is one reason why they become so attracted to writing-to enter the world of play and communicate with friends and loved ones in this exciting new form.

What You Can Do

There are many ways children's writing can be supported in the classroom and at home. Here are a few suggestions: Help children start by learning the first letter of their name and go from there. Not surprisingly, the first word many children want to write and spell correcdy is their own name. Since they're likely to encounter their name again and again at school, this is a good place to begin introducing a more formalized writing process. I recommend using all capital letters, since this is a bit easier for children's fine motor coordination. Support children's writing by encouraging parents to write to them. Children's writing will develop more quickly if they are given many opportunities to practice. Suggest that parents have paper, pencils, large markers, and large crayons on their trips to the doctor's office or other appointments. It will make the time go faster and give them lots of fun moments to share in writing to one another. Also suggest that they model some of the common purposes for writing. For example, we all make lists for shopping at the grocery store and take telephone messages when someone's away from home. Helping children understand the purposes of writing-what writing can do and, in particular, what they can do with writing-will help them understand its function as a part of other activities in their lives, such as speaking, drawing, and playing. By encouraging children to experiment with writing materials, they'll begin to master each of these demonstrations of writing long before they're able to produce messages that are generally readable and interpretable by others. These informal lessons will ensure that children enjoy writing and see it as an important form of communication.

Make a Picture Dictionary

January 6th, 2010 by willardbeard1964

One of the most important skills for children to develop in the kindergarten year is the recognition that letters and sounds are related. We often call this “the alphabetic principle,” which is the notion that speech sounds can be connected to letters in a predictable way. To grasp the alphabetic principal, children need to understand that:

  • letters represent speech sounds
  • letters go together to make words
  • changing the letters changes the sounds and the words

This is not an easy concept for many young learners to absorb. As opposed to many other languages, English has many more sounds (what we traditionally call “phonemes”) than letters. This means that many of our letters make more than one sound. The letter E, for example, can stand for as many as eight different sounds in English. Just try this sentence: “The smell of the fern reeked despite our efforts.”

Because the roots of English come from different languages, we also have many sounds that can be spelled in more than one way. For example: ow, ou, and f for gh. There are also many words that sound alike but are spelled differently, such as bear and bare.

Our vowel sounds alone can produce lots of confusion for young children. In fact, many teachers stay away from teaching vowel sounds until later on in first grade. At last count we have about 19 different vowel sounds, and only five or six letters to spell them with (A,E,I,O,U, and sometimes Y). We have long A as in cake, short A as in bat, and R controlled A as in bark. No wonder it takes children two to three years to learn how to match sounds to their letter names!

There are plenty of specific activities you can engage children in to help them learn to make letter-sound correspondences. Try to stay away from workbook-like tasks, as they can make the joys of learning the alphabetic principle seem deadly dull. Here are some activities to try in your own classroom:

BEGIN WITH BOOKS

Reading to children is often the best way to reinforce letter-sound connections. You can help by pointing to the print as you share picture books. Alphabet books are especially useful, since they often include pictures of words that begin with the letter name.

LABEL IT

Provide labels, captions, and other print wherever they serve a purpose. Enriching your environment with labels and signs helps children begin to see the connection between words and their corresponding sounds. seeing a menu at snack or lunchtime gives children a meaningful experience with letters and words.

BUILD A WORD WALL

There are lots of ways to reinforce letter-sound correspondences throughout your day. Create a word wall that emphasizes common sounds children hear.

PROVIDE LOTS OF LETTERS

Children notice the shapes of letters when they do alphabet puzzles or use letter-shaped cookie cutters in damp sand or play dough. Magnetic letters and alphabet blocks allow children to explore letter-sound connections, arrange and rearrange letters to form words, and become more aware of the sequences of sounds within words.

DISPLAY LABELED PHOTOS

Young children love to look at photographs of themselves and their friends. Dispky snapshots of every child in your class, then ask them to match up faces to names. This provides experience in letter recognition, naming, and noticing the initial sound (or phoneme) in a name.

Once children start to make connections between letters and sounds, they'll be able to begin to read some very simple texts. First, they'll sound out the words very, very slowly, as if they're “glued to the print.” Soon they'll begin to polish their newfound skills, recognizing letters and sounds very quickly, while connecting them to smooth, meaningful reading.

The alphabetic principle is definitely one of the more important skills for children to develop. But don't try to rush it. Lots of experiences with print will put them on the right track toward learning - and loving - to read.

Child care (0-5 years)

January 5th, 2010 by willardbeard1964

The number of women participating in the Canadian labour market has increased substantially over the past 25 years. According to Statistics Canada, the labour force participation rate of women with children under three rose from 28% in 1976 to 63% in 2003. Similarly, the number of women with children between the ages of three and five increased dramatically, from 37% in 1976 to 69% in 2003.1

The need for non-parental care, or child care, has risen alongside the ever increasing number of women joining and returning to the workforce. In 1996-97, almost 2 million children under 12 years of age were participating in some type of non-parental care. Approximately 25% of infants under one and 46% of children between the ages of one and five were involved in some form of non parental care.2

Non-parental care or child care can be defined as the care of children in their home, someone else’s home or in a centre, where care and education are provided by a person other than an immediate family member. As child care programs vary in location and design, so do the levels of quality.

The provision of quality in child care centres is mainly determined by three factors:

*
low child-adult ratios;
*
highly educated providers with specialized training; and
*
stimulating environments.

Activity Plan 5-6: Frosty Fun

January 4th, 2010 by willardbeard1964

Ready-To-Use Teaching Ideas: Math/Science

Materials:

  • jar of small pebbles
  • pie tins-one for each child
  • tiny twigs for arms
  • large toy clock

Developing Skills:

  • observation
  • recording data
  • investigating
  • prediction
  • basic math and science concepts

ACTIVITY

With the coldest two months of winter ahead of us, it's a good time to play with snow. Let children experiment and predict how long it will take for a snowman to melt inside the classroom.

Tell children that they are each going to build a small snowman. This snowman will have only two sections, a body and a head. Show children what the first ball looks like and build a snowman with them watching. Explain that they need to be able to bring their snowman into the classroom in a pie tin.

Once children make their snowmen, allow them to decorate the snowmen with the small pebbles and the tiny twigs.

Have a designated area set up to display the snowmen in their pie tins.

Hold a discussion about the length of time it will take before the snowmen completely melt. Time is a difficult concept for children to grasp at this age. Accept all predictions and make no judgment statements. The purpose of the lesson is for children to observe, record data, predict, and think in a scientific manner.

Record children's predictions on a large chart and write down each hour that passes. Show children how each hour passes on the toy clock. Make references to what they have already done in your daily routine. This will help children make sense of the passage of an hour or three hours. Ask questions, such as: “Which snowman will melt the fastest?” “Will they all take the same amount of time?” “What will happen to the pebbles and twigs as the snowmen melt?”

Remember: Time is a difficult concept for children to grasp and younger students' predictions may be way off. You might give them a time limit on the number of hours they can guess.

Curriculum Connection: SCIENCE

On a day when it is snowing, take children outside to catch snowflakes on pieces of black construction paper. Observe the snowflakes through a magnifying glass. Invite children to count the points on each snowflake and discover that, despite being shaped differently, each one has six sides or points. Using white tempera paint or a white crayon on blue paper, suggest children draw and record a snowflake they observed. If it doesn't snow, show children enlarged photographic reproductions of snowflakes.
