Naturalists recognise animals by their footprints in the ground! Let's become trackers for a day, learn to observe fingerprints, make our own tracks, and compare them!

A black and white picture of three animal tracks.

Bath Bombs (CC 1, 2, 5)

Chemical reactions can be visual, calorific, auditory, or even explosive. So? What does it all mean? It means we are going to create a reaction that will make FIZZ: we are going to create bath bombs!
