M’s top request for summer activities was “science where you mix up things with water and make stuff”. So I ordered Super Science Concoctions, and last week we had fun with food coloring and water. First, we placed a few drops of color in a jar of hot water (blue), room temperature water (green) and ice water (red). We let them sit and watched how the food coloring was distributed throughout the jar by nothing other than molecular motion. We had to wait a long time for all three jars to be uniform, but we managed to be patient and resist the urge to stir. We enjoyed comparing the speed of mixing at different temperatures.
As we watched our jars, we mixed food coloring with a small amount of water and made our own watercolors. The girls had a blast experimenting with the vivid colors.
