Roller Coaster Mayhem!!

In the Omega Unit we are building roller coasters for a physical science project. We have to use "Omega Money", fake money given to us by our teachers, to "buy" all of our materials. These materials are common household items such toilet paper rolls, rolls, cardboard, and tape. My group has basically finished our roller coaster. It's pretty cool and surprisingly demonstrates physical science well. The roller coaster shows potential energy, kinetic energy, and Newton's laws of motion. All in all, it's turning out to be a fun project and I hope my group well get a good grade. mayhem
