Learning Objectives. Explain how energy travels with a pulse or wave. Describe, using a mathematical expression, how the energy in a wave depends on the amplitude of the wave. All waves carry energy, and sometimes this can be directly observed.

Calculate the intensity and the power of rays and waves. All waves carry energy. The energy of some waves can be directly observed. Earthquakes can shake whole cities to the ground, performing the work of thousands of wrecking balls. Loud sounds pulverize nerve cells in the inner ear, causing permanent hearing loss.
Energy, not matter, travels by waves. Although it appears that water is moving in one direction when it is wavy, in fact, individual water molecules actually move up and down, not in a sideways direction.
Investigate alternative energy sources, efficiency, and sustainability in this collection of unique energy science experiments. Investigate the world around you with science experiments developed specifically for third grade.
Key points. Waves contain kinetic energy. By using turbines, the kinetic energy of waves can be transferred into electrical energy. Wave power does not use up any fuels and so it is a great...
GRADES 3-5. SUMMARY. Students will understand how energy travels through transverse and longitudinal waves. CORRELATION. 4-PS4-1. cause objects to move. Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can. Science & Engineering Practices.
