The Catapult Challenge Project is a great way to kick off a Forces and Motion Unit. With this project, students will conduct research about the first catapults. Once the research is complete, the construct a catapult using the criteria set then complete the challenge launch.
This is a fun way to get kids excited about motion! A rubric is included with the research and task components. This could be completed in 3-5 days depending on modifications for your students.
