A student teacher produced a worksheet a drawings of various objects, such as a teddy, a mirror, a hat, silver foil etc. and the children were asked to circle all the objects that reflect light. The student expected the children only to circle the mirror, and foil and the other shiny objects. Would this be correct? Why or why not?
