This is a website designed to be a resource to students and teachers for learning/teaching direct and inverse variation through the application of buoyancy and density principles. Density and buoyancy have many practical applications, especially in fluid mechanics, which I was able to research as part of a team in the UNC applied math fluids lab. If you would like to learn more about that, you can click here or "About the UNC Applied Math Fluids Lab" above. "Helpful Links" contains sources and other external resources to learn more about density and fluids. Teachers can click on "For Teachers" for lesson plans and other activities you can use in your classroom. Students, you can click "Start" below to get started on a lesson and game you can play to learn more about direct and inverse variation through density and buoyancy! As a note, this site has trouble with Internet Explorer. If possible, I would suggest using Firefox or Safari instead.
