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. Just in time or my weather unit this week! I thought this was a really cool experiment that I must do with my students to introduce a weather topic or even the water cycle!
Really fun activity to show why it rains. 5th graders would enjoy the hands on aspect, and it also does a great job of explaining a concept we can't see standing on the ground. Ties into our weather lesson (TEKS)
