- 6-PS4-2 Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials
- 4-PS4-1. Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.
- 4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
