Teacher Resources for Instructional Planning


Grade 8, Science Std 12.1: Describe how earthquake waves, sound waves, water waves and electromagnetic waves can be destructive or beneficial due to the transfer of energy. • Describing longitudinal and transverse waves • Describing how waves travel through different media. • Describing the destructive nature of primary, secondary and surface waves.

Lesson Plans: The Halls Are Alive With the Sound of Music In this lesson, students examine the relationship between the physics of sound and concert hall acoustics. Students perform a lab experiment in which they determine the speed of sound, a key variable in concert hall acoustics. From Vibration To Sound To distinguish between a transverse wave and a compressional wave. Understanding Waves Students will gain an understanding of the properties that all waves have in common. Wave Properties In this lesson, students will learn the components of a wave, then discuss the effects of wave height, wavelength, and wave period in determining the overall size of a wave. Earthquake Waves And Their Destructions Students will learn characteristics of primary waves and secondary waves. Waves Students will be able to state the properties that a medium must possess in order that waves may be transmitted through it. Students will be able to tell the essential difference between a longitudinal and a transverse wave. Wave Motion Identify and explain the difference between a transverse and longitudinal wave.
