Bath time is a great time for playing with soap and exploring its physical properties. Before your child gets in the tub or shower, offer a new, dry bar of soap and invite her to explore what it looks, smells, and feels like. Is it hard or soft? Rough or smooth? Together, make predictions about how the soap might change after it’s been in the water awhile.
Then encourage her to immerse the soap and see what happens as she rubs it on her skin, a washcloth, or even the side of the wet tub. What does she notice? Can she tell you what happened to the soap and how it changed in size, shape, and texture? Is it smaller? Softer? Slipperier? And where did all those bubbles come from?
