Make a hypothesis about what will happen when you mix food coloring and milk with a cotton bud covered with dish washing liquid. Test your hypothesis by conducting the experiment. Remember to read the procedure carefully before you begin. Take photos as you conduct the experiment to use as a part of your learning reflection. Materials Full cream milk Food coloring Dishwashing liquid Cotton swab Plate Instructions Pour enough milk onto a plate to cover the bottom. Drop food coloring into the milk. Dip a cotton swab in dish washing detergent liquid. Touch the coated swab to the milk in the center of the plate. Don't stir the milk; it isn't necessary. The colors will swirl on their own as soon as the detergent contacts the liquid.
