Support your STEM program with this DIY Roller Coaster Marble Slide. With this activity for smarter learning, you can literally make a mash-up of two fun games! Introduce users to motion, momentum transfer, gravity, and centrifugal force. Or play the slider game: use the wheel to raise marbles and release them - aim with levers on both sides. Play marble-pool: strategically place marbles so the striker marble coming from the slide track sends them into corner or side pockets.
