4.PS3.B.1

Provide evidence to construct an explanation of an energy transformation(e.g. temperature change, light, sound, motion, and magnetic effects

4.PS4.A.1

Develop a model of waves to describe patterns in terms of amplitude or wavelength and that waves can cause objects to move.  

[Clarification Statement: Examples of models could include diagrams, analogies, and physical models using wire to illustrate wavelength and amplitude of waves.]
