# Simulations Library

This library is a collection of prebuilt simulations together with classroom tested curriculum materials. The simulations can typically be used in many ways, in many different classes, and at many different levels. As one example, the screenshot above is from a simulation that can help students understand the seasons, solar energy, and climate science. It can be used for simple demonstrations in class, for a set of laboratory experiments, or as a modeling project in multivariable calculus classes, linear algebra classes, or modeling classes. Students can use the simulation as is or they can build it from scratch.
