Eighth grade science students are applying the laws of motion by building a mousetrap car. For the STEM activity, students were given choices of different materials to build their cars and then built them in class. As part of the lab, students will measure force, speed, and calculate work. The goal is to build a car that will travel at least 5 meters. Bonus points are given for the longest distance, fastest, best design and using the most recycled materials.
