This is by far my favorite project that I have done with my students! Please see the preview and product video for explanations and examples.
Note: You will have to provide your students with materials to build a catapult. (I ask families to donate items) You can have your class create any type of catapult you would like from very basic to more complicated. I gave my students free range to design and build whatever they wanted.
This product gives you step by step directions to complete the product and test the catapults. I have included the Google Sheets I used for testing days as well as the grading rubric. They are given to you as a Google Doc and a Google Sheet so they are 100% Editable!!!!!
