9. Water Cycle
We are continuing our list of quick and easy STEM activities for elementary school students with the activity that is very easy and does not require any special materials. You will need a plastic sandwich bag, blue food coloring, and some water. Pour a few drops of food coloring into the small measuring cup with ¼ of water. Pour the water in the bag and seal it. Use the tape to attach the bag to the window and observe. Water will evaporate, then turn liquid again once it is cooled.
