The hydrosphere is made up of all the water on Earth. Water exists in three forms-liquid, solid, and water vapor-and changes from one form to another. Water moves around Earth in the water cycle in which some of the water in oceans and rivers turns into water vapor that goes into the air to form clouds. The water is then returned to the surface of Earth as rain or snow. This cycle repeats over and over. Water is necessary for life on Earth to exist. Some people are not careful about keeping our water clean, and others help clean it up. Scientists are working to find new ways to keep Earth's…mehr

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.
