Weather: Fill the cup with water. Put shaving cream on top for a cloud. Explain that when clouds get really heavy with water, it rains! Then put blue food coloring on top of the cloud, and watch it rain.
Boats [Science] Children drop a ball of clay into a small tub of water to see if it will float or sink. Next, they form a boat from the clay and try to make a boat that will float. They try putting animal counters in the boat to see how many the boat will hold without sinking. You can also try making boats with aluminum foil. (Children are exploring density.)
