Challenging Kids

My students are so creative and productive - who could ask for more? Today one group put three motors together to make something that looked like an arm with two elbows. I saw at least three catapults, and one group made a machine that stood three feet tall (and did not fall when it ran). I tried to stump them with a nested loop and recorded action in Logo (Mindstorms' programming language) AND seeing who could make the tallest machine. Next we will learn about the wait and switch buttons. The week will culminate with a robot dance contest on Friday.
