Students observe the ways of water. They play with sinking and floating items, and they fill and empty containers. To learn about the power of water, they make and watch waves and get to see a paddle wheel at work. They also work at a 'water table' where they can use sponges, wood and metal in their aquatic experiments. Teachers discuss activities they have devised for their own students, such as letting the children paint with brushes and water, take walks in the rain, and visit beaches to play in water and sand. And sand makes an appearance too as children work at the 'sand table', where they toy with dry sand and wet sand, and its close cousin, mud.
