Boost Their Learning Trajectory
Build your own authentic catapult with planks, a little glue and the help of easy, step-by-step instructions. Then let the fun and experimentation begin! What shoots farther, a marshmallow or a piece of macaroni? How does the object’s course change when you pull the arm back to different points? If you make the flight deck higher, how does it affect the hurl? Includes pre-drilled planks, wood glue, leather strap, ruler, rubber bands, cup, 2 balls, target mat, fasteners and instructions.
