All you need is a container, some water and some things to play with. Half fill a plastic tub, the bathroom sink or even a baby bath with water. Choose a few different containers and sit with your child and play together. Talk about what is happening as you measure, pour and gently splash.How many of those cups does it take to fill the teapot? What about these little bottles?Can you squeeze all the water out of the sponge?Oh, no - we got wet!
