Can you see in the dark?

In science first class are learning about light. They discussed sources of light and the type of energy these sources used such as, light bulbs energy coming from electricity. The boys and girls agreed that we need light to survive. As part of science week and using resources from SEAI (Sustainable Energy Authority of Ireland) the class investigated in the absense of light, can you see objects in the dark? The class made predictions and then tested each object in a dark box with a viewing tube and recorded their results. Finally they drew conclusion from their experiment. .
