Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

Develop models to describe the atomic composition of simple molecules and extended structures.

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.

Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.

Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.

Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

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.
