 Playing with water can be fun for a child and can also be used for learning. You can give the child a small cup and a larger bowl and say, how many cups do you think will it take to fill the bowl? The child can make a guess and then test it by filling the cup with water and pouring it into the bowl. Talk about what they find. How many cups did it take to fill the bowl? Was it more or less than what you guessed? By making a prediction about what is going to happen, testing it, and talking about it, the child is learning to think like a scientist.
