In this science/math activity, you do serial dilutions using breakfast cereal! Each time you dilute the milk/cereal mixture, you end up with fewer and fewer pieces of cereal in the cups, lowering the cereal concentration in each ½ cup of milk as you go. (Concentration refers to how many pieces of a certain substance are contained in a certain amount of something, like liquid or air.) Serial dilutions are often used by scientists to quickly and accurately lower the concentration of a liquid. Do serial dilutions with another color, like blue, to test how color mixing works with different dilutions. Instead of adding plain water to the cups, add water containing yellow food coloring to each cup. Congratulate him - he's made a series of serial dilutions: Step 12: Ask your child to compare the color in the cups.
