Waves are disturbances that transfer energy from place to place. All waves have amplitude, wavelength and frequency regardless of whether they are mechanical waves, electromagnetic waves or waves in the ocean! Students will learn more about the role waves play in everyday life and why understanding them is so important. With fun demonstrations and a hands-on activity, these concepts are more easily understood. One of the 16 volumes in the Physical Science in Action series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Physical Science--properties and changes of properties in matter, motions and forces, and transfer of energy. This program includes a teacher's guide. (MM)
