The Sun is a star, an object in space that makes its own light and heat energy. Energy gives something the ability to do work. Light energy does the work of making things visible, and heat energy does the work of making things warm. The Sun is so huge that a million Earths would fit inside, and instead of being made of rocks and soil like Earth, the Sun is made of helium gas and hydrogen gas. The Sun is very hot and produces its light energy and heat energy when hydrogen and helium atoms rearrange in a nuclear reaction. (Atoms are defined.) The Sun's energy makes life possible on Earth, which…mehr

Produktbeschreibung
The Sun is a star, an object in space that makes its own light and heat energy. Energy gives something the ability to do work. Light energy does the work of making things visible, and heat energy does the work of making things warm. The Sun is so huge that a million Earths would fit inside, and instead of being made of rocks and soil like Earth, the Sun is made of helium gas and hydrogen gas. The Sun is very hot and produces its light energy and heat energy when hydrogen and helium atoms rearrange in a nuclear reaction. (Atoms are defined.) The Sun's energy makes life possible on Earth, which is the right distance from the Sun to have the right temperatures for living things to exist. Plants use the Sun's light energy to grow and make sugar for food, and the sugar made by plants also feeds all the animals. Astronomers continue to study the Sun and how it works. Pronunciation guide included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5, Word count 322, Lexile measure 540L.
Autorenporträt
Dr. Rebecca Woodbury received her Ph.D. in biophysical chemistry from the University of New Mexico in 1992. She was awarded a National Science Foundation postdoctoral fellowship in the Department of Molecular Biology at the University of New Mexico, followed by a Burroughs Wellcome Fund Postdoctoral Fellowship in the Department of Molecular Biology at the University of California, Berkeley.While home schooling her three children, Dr. Woodbury was unable to find a curriculum that provided a solid foundation in science. She left academia, and using her scientific background coupled with her love of learning, she developed a series of science books for kids.The Real Science-4-Kids curriculum provides students with a solid foundation in science and gives them the tools to evaluate scientific data on their own. "We should not rely on the 'experts' but instead learn how to critically evaluate every scientific claim," states Dr. Woodbury."In these uncertain times with so many social, scientific, and economic problems, it is not enough to teach our kids what to learn. We must also teach them how to learn, and we must encourage our kids to learn from others. Part of learning from others is to know how to engage in productive debate."The Real Science-4-Kids engaging, kid-friendly curriculum provides a solid science education in chemistry, biology, physics, geology, and astronomy. This curriculum is used in all 50 states in the US and many other countries. Dr. Woodbury and her publishing team continue to develop and test new products for both home school and public school students.
