Teachers, save “STEM 2: Marble run” to assign it to your class.

I always loved playing with marbles when I was younger. I also loved using whatever i had around the house to make marble runs. Use whatever you can to make a marble run. Experiment using cards in different ways as well as anything that can be used for tubes. Take a photo or video and add tell me about your marble run. Challenge: Take it vertical! Is there anyway you can make a marble run that runs down the wall? 🤔
