Which was the best reflective material we could see in the dark?

Our second light and dark investigation had us looking at different materials to see which was reflective and which wasn't. This was quite tricky as we first had learn what reflection meant. We did this using a mirror and trying it out with torches on the whiteboard. We were able to see the light on the whiteboard as well as on the mirror. We tested lots of different material to decide which would be best to make a reflective hat out of. Children made their hats out of different materials. We then tried out the hats in our Little Bears Dark Cave with our torches to decide which hats were the best reflective hats. Mostly we decided that the shiny paper and the cellophane hats were the best reflective hats to see in the dark.
