What do you learn:
The use of elastic potential energy began way back in medieval times. To attack other castles, massive catapults were created to exert a huge amount of elastic potential energy and kinetic energy! Build your very own catapult and launch a projectile at your “enemies”! Control the range of your projectile by varying the amount of force used to load the catapult. Identify where elastic potential energy and kinetic energy are stored in the different parts of the catapult. Ready, set, launch!

For the HOT! (Hands-on-Time) segment, explore elastic and non-elastic objects. Construct a DIY launcher with cups and balloons. These activities allow you to explore how elastic potential energy is converted into kinetic energy. Have fun!
