I developed this project when I was tired of the typical PE/Work lab where students climb the stairs. It's my best selling item for a reason. It's fun for students, the only real cost is for masking tape and or hot glue, and it's easy to grade. :) Depending on your schedule, it can fill 3-5 class periods. Students calculate gravitational potential energy, expected exit velocity, actual exit velocity, kinetic energy on exit and energy "lost" due to friction and sound.
Students use paper book covers, paper bags, paper plates, cereal boxes, etc. to build a working roller coaster that will keep a car (marble) inside for at least 8.0 s. My longest time was 22.3 seconds and it was only 1.15 m high. There are photos of finished projects in the power point presentation.
The bundled materials include a teacher lesson, an online simulation activity, a Kahoot quiz to be sure they know what they are doing (it will save you answering a lot of dumb questions that are in the power point and on the rubric), a grading rubric, and a follow up quiz with a key.
