Have students get in groups of three to four people and make a ring with tape on a flat surface, the goal is to use light to direct your robot and push everyone else's robot out of the ring but keeping their own in. Decorate or label your robot to keep track of whose is whose. Have students discuss what they learned from playing the game and journaling on the page given.
