I'm currently engaged in a force and motion unit with my own students. Our theme is roller coasters. In my research for this unit, I came across an interactive website where students can manipulate various aspects of the rollercoaster and then see the outcome of the changes. The website is Funderstanding's Rollercoaster. http://www.funderstanding.com/k12/coaster/
