This is the tree that I'm going to do in my preschool. The colors are fun in here, but mine are different. @Kate Olsen and I are going to put batting over the cardboard circles, and velcro on the back. We will be able to change out the circles for seasons, holidays and for whatever we're discussing in preschool (i.e. colors, food, camping, bugs, or whatever)!!!
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.
