Paper Cup Heads With Grass Hair
If your child still insists that they want to make mud pies, let them. Have them draw a face on a Styrofoam cup or decorate it in some other way. Add small rocks and then let them put potting soil into the cup. Sprinkle grass seeds onto the soil and cover it with another small amount of soil. Let them water their person and then place it in a sunny window. When the grass grows it looks like the person has green hair.
