History records Isaac Newton as a genius but most toddlers can tell you what will happen if you drop a ball! OK, so gravity wasn't merely the observation that things fall, so much as the reasoning as to why, but introducing such basic concepts to young children genuinely is laying the foundation for a scientific education. Next time you are bathing your little ones, take some time out to look at floating and sinking. Add a number of waterproof toys into the bath and see which ones float, and which ones sink? Can you find objects that float when they are bobbed on the surface but that sink when filled with water?
Bathtime presents a fabulous opportunity for little ones to explore water and its properties. Make sure that as well as experimenting, you talk with your little ones; discuss what they are observing and if you can explain it simply, then do so.
Pumice stones are items that you naturally expect to find in a bathroom. Pumice is extraordinary - it is volcanic in origin, created when superheated rock is spewed from a volcano that then cools very rapidly - usually because the volcano errupted underwater. Although it is a rock, it floats in water, so it's a wonderfully confusing item to play with at bathtime, and when you've had enough fun watching it float, you can use it to scrub your little ones clean...good, practical fun!
