In technology class this week we have been experimenting with wheels and axels, and we built cams, a oddly shaped wheel pushing a load up when you turn a crank. We made it out of paper, and it actually works pretty well. I still don’t know what the load is going to be, I am thinking a jack-in-the-box, and the puppet comes out when you turn the wheel. But I’m not the most crafty person, so we will se how that goes. Overall, I think the project was a good way to teach us about wheel and axles, and I look forward to more projects in the future.
