This experiment is a hands-on, cooperative learning experience. It was created as part of a force and motion unit. Students work together to apply what they have learned about force and motion, acceleration, gravity, momentum, speed, etc. and apply it by designing and building a rollercoaster. This can be used to assess students' mastery of the concepts in how they apply them to make their rollercoaster successful. The format of the experiment includes creating a proposal before beginning construction. The purpose of this is to help the students pause and think critically before jumping to the fun of building. Also, it allows for intervention from the teacher in case students need a push in the right direction. This is designed as a trial and error experiment for students to problem solve and engage in productive struggle... while also having fun!
