What you need

Three shallow unbreakable dishes, a little water, blue and yellow food coloring, and a spoon.

Age: 3–5 years; choose for the individual child.

Let's make it happen

  1. Adult places a little water in two dishes and adds a drop of blue coloring to one and yellow to the other.
  2. Guess what will happen when the colors meet. Adult pours a little from each dish into the third and stirs.
  3. Notice and describe the result; shades can vary with the dyes and amounts. Empty the dishes and clean the surface.

Adult checks for sensitivities, handles the coloring and water, stays within arm's reach, prevents tasting, and empties dishes and dries spills immediately afterward.
