Classroom Ideas

After watching the clip, children could be asked to investigate the real world applications of lenses (such as magnifying glasses or reading glasses). Alternatively children could create a maze inside a shoe box, and be challenged to reflect a beam of light, using mirrors, around the maze. This could be linked to Mathematics and children could be asked to measure the angles of the light as they are reflecting from the mirrors.
