How I Use It
I've used many of the physics simulations on this site back in high school, as well as in preparation for this review.
This site is a great source of basic math and science simulations. There's a wide variety of simulations to pick from which make testing different aspects of testing things fun. For example, the buoyancy simulation has a lot of fun options to find the relationship between volume, mass, density, and an object's ability to float. The ability to change all these variables make the simulations both fun and a great learning tool.
