During the field trip to Camp Trivera we created catapults. Describe what you did in the stem lab creating and testing out the catapults to what we have learned in class concerning energy? If you did not get to attend the field trip I want you to Google what a catapult is then describe how it is used to what we are learning in this energy lesson.
