Spooky goings-on today in school as we had a day devoted to Halloween. The children pulled out the stops with some sensational costumes (and make-up). We did pumpkin carving, STEM activities with flapping bats and made our own jam jar lanterns using cotton wool and glow sticks (ideal for guising later on this evening). We even looked at the science behind objects which glow in the dark. A common misconception is that light sources need heat but this is not true, as we proved by looking at bioluminescence and even chemiluminescence (an amazing word, we thought).
