Unit Standards:
PS3-5 D. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. (MS-PS3-5)
PS1-4 D. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. (MS-PS1-4)
PS4-1 E. 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. (MS-PS4-1)
PS4-2 F. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. (MS-PS4-2)
