This math experiment comes from Growing in 5th Grade! Kids compare the suds created by different dish soaps. They add 1/2 cup water and 2 drops of soap to a water bottle and shake! Then, they measure the height of the suds! Which soap created the most suds?! Is this a physical or chemical change?! Science - Go With The Flow! (laminar flow) Visit Exploratorium to explore water patterns (turbulence) created by shaking dish soap, water, and a drop of food coloring!
