During our science lesson, the children learned that we are able to see because light reflects off non luminous objects and this is then sent to our eyes. When light reflects off an object, it bounces off at the exact same angle. To further develop learning, the crew made periscopes. They were able to explain how light enters the top wndow and hits the first mirror, this light is then reflected at a 45 degree angle down the periscope to the second mirror. The light bounces off this mirror into the eye.
