Grade 4 has been studying Energy in Science. As part of the unit, they have been exploring wave properties. What better way to explore a concept in science than with the use of some kind of candy? So they created a Gummy Bear Wave Machine! It’s just duct tape, wooden skewers, and gummy bears, but it makes some really striking, beautiful effects when set in motion. As the gummy bears move up and down, energy is being sent from one end of the wave machine to the other. The duct tape twists in between each stick and passes it onto the next bit of tape between the sticks. This process continues until it reaches one end and then continues back the same way in which it came from. Once the wave machine was complete, guess who got to eat the leftover gummy bears?
