This week in technology we learned about wheels, axels, and cams. It was really fun because it was a lot of simple machines! WE got to build a catapult with a game to go along with it. I made a very simple catapult made out of popsicle sticks and rubber bands. My game was that you have to try and knock down cups while using the catapult, this was a very hard game. Overall this was a great week for technology!
