Materials: Plastic plate, whole milk, food coloring, q-tip, liquid dish soap
Activity: Pour whole milk on a plate. Add a few drops of food coloring. Dip a q-tip in liquid soap. Poke the food coloring with the soapy q-tip. Keep the q-tip still, and watch what happens to the food coloring!
Research Questions: What happens to the food coloring in the milk? How do different liquids affect color behavior? Whole milk, 2% milk, fat-free milk, cream, water? How does amount of soap on q-tip affect color behavior?
