There were certain things we learned. Cams/mechanics and the electric board, the automaton, and a catapult. I learned that the triangle is the strongest shape because aside cannot change unless the other side changes. I learned about automaton and the functions it could do. I learned its history and learned some of the most famous ones such as the boy writing a letter. I learned how to make a catapult out of popsicle sticks and to launch them. I learned how to cut off the outer layer of the wire to just leave the middle in there for the electric boards.  I learned that the fulcrum is the point where you move something and the point does not move. Finally, I learned about the cams and cranks that could create a function for the automatons and could make something look real. I learned so much in technology.
