1. By Nate and Ammanuel Catapult Make 2014

2. OUR GOAL Our goal throughout this project was to successfully create a catapult with popsicle sticks.

3. MATIERALS The materials used to make the catapult are….. Popsicle Sticks A Screw A Rubber Band A bottle cap Masking tape Penny roles Hot Glue

4. STEPS IN MAKING THE CATAPULT Obtain the materials Start building the structure/base with popsicle sticks and hot glue After finishing the base, we made the arm Glue the head on the arm Taped on a roll of pennies Drill holes so we could put the arm on the base/structure Attach the arm by putting a screw through the holes We then tested it We noticed that it didn’t go so far So we put on a rubber band to see if it shoots farther We then tested it, it went farther

5. DIFFERENT CHALLENGES ENCOUNTERED THROUGHOUT PROJECT AND HOW WE OVERCAME THEM We couldn’t find the right screw size to attach the arm on the base – We went to hope depo to find the right screws It wouldn’t shoot long enough – So we put a rubber band around the arm of the catapult.

6. LEARNING AND HOW IT WAS APPLIED We learned that we need to do double layers popsicle sticks – So we did a new catapult after our original one and did double popsicle sticks That pennies was the best for weight – So we used pennies for the weight on the bottom of our catapult.

7. FAILURES AND HOW WE LEARNED FROM THEM Our first model did not have enough support – So we learned that we should do a double-popsicle stick structure for support, that’s why we needed to make a new one The base of our first prototype was uneven – So we learned that we need to be more careful when hot gluying.
