Overview

Children are introduced to the physics of sound. Energy causes air molecules to move slightly back and forth. The energy is passed from molecule to molecule, causing a longitudinal sound wave. The more energy used, the bigger the longitudinal wave and the louder the sound. The ear contains a thin flexible part, the tympanic membrane, that picks up the motion of the molecules in the sound wave. Sound waves can travel through other materials in addition to air. Sound travels faster through materials with tightly packed molecules. Some examples are given. Atoms, molecules, energy, and longitudinal waves are defined. Students are invited to try a simple experiment. 24 full-color, illustrated pages. Reading Level 1-3, Interest Level 2-5. Includes a pronunciation guide for scientific terms.

Author Information

"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 curriculum, with its engaging, kid-friendly Student Textbooks; Laboratory Notebooks full of real science experiments; and easy to use Teacher's Manuals, provides kids with 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, including leveled readers and mini books, at the Real Science-4-Kids Albuquerque headquarters."
