Classroom Ideas

Students could play around with infinity reflections in the classroom. Face two large mirrors in front of each other and ask students to take turns by standing in-between the mirrors. Students could take photos of each other’s multiple reflections and discuss the number of images they see and how their sizes relate to each other. Now encourage students to investigate optical illusions. The comparison between light and snooker could be extended by using a laser and mirrors to line up various snooker shots.
