Being scientists to explore light

We have been exploring light. Yesterday we used black cardboard to make a telescope. We put a sticker on another piece of cardboard and had to explore how many holes were needed to be able to see the sticker. This lead to great discussions about the size of holes letting in different amounts of light, the angle of the sticker and the angle of the light coming into the telescope, where people were standing in the room-close to a window/far from a window. We also came up with interesting wonderings about light including does the colour of our eyes make a difference to how we see? What if there was no sun, moon or stars to give us light? How is one light brighter than another light? Where does the light in light bulbs come from?  Plus many more! The children have been showing great scientific thinking throughout these explorations and discussions about light.
