Adjust frequency, amplitude, and perturbation in this simulation to graph the trajectory of a mass at the end of each pendulum.

Adjust the rotation in this simulation to see how particles of fluids move.

Explore what happens when a force is exerted on a ceramic material. The molecular structure of the material affects how it responds to an applied force at the macroscopic level.

Explore what happens when a force is exerted on a rubber tire. The molecular structure of each material affects how it responds to an applied force at the macroscopic level.

Explore what happens when a force is exerted on a metallic material. The molecular structure of the material affects how it responds to an applied force at the macroscopic level.

Explore what happens when a force is exerted on a polymeric plastic material. The molecular structure of a material affects how it responds to an applied force at the macroscopic level.

In this activity, students explore phase change at a molecular level. (Requires Java)

Discover the concept that energy transfer and molecular motion cause the change in state from a solid to a liquid. Also compare state changes of water to the state changes of other substances.
