**Next Generation Science Standards covered in this unit: **

**MS.PS2.1:** Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.

**MS.PS.2:** Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

**MS.PS4.1:** Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
