Kinetic Potential Energy This STEM project is an engineering project that incorporates both math and science (kinetic and potential energy) concepts. It will span over a four day period. My students completed this project after a mini-unit on potential energy and kinetic energy. Students also changed one variable on their catapult at a time and took data on that change to see which change was the best for their catapult. For example, the angle that the catapult was pulled back was a variable. Students changed the angle to 110 degrees, 140 degrees, and 170 degrees. Students then tested each angle ten times to determine which one gave the catapult the best accuracy. Then, students determined the probability of each of the angles.
1st Day - I explained the project. Students met with their partner and brainstormed a catapult idea. They each had to come up with an idea. They also were allowed to research trebuchets and catapults on the internet.
2nd Day - Students finished brainstorming and started building their catapult. They had to stay within budget! Students built their catapults.
3rd Day - Students started running tests on their catapult.
4th Day - Students completed tests on their catapult. Students received three tries to launch their marble in the center .
