What You Child Will Learn By Doing This STEM art activity

  • Basic Science Concepts: Explain to your child how everything is made up of small molecules and that the wax molecules of the crayon resist or “push away” the water molecules.
  • Cause and Effect: Teach your child the concept of cause and effect as they see the crayon’s effect on the watercolor paint soaking into the paper.

Materials Needed: 

  • Paper 
  • Watercolors 
  • A Paintbrush 
  • White crayon


  1. Have your child draw a scarecrow or other Fall image on the paper using the white crayon. You can also draw images on the paper beforehand so the revealed image will be a surprise.
  2. Dip your paintbrush in water and watercolors and paint over the entire page.
  3. Watch how the watercolors resist where the white crayon is but show up brightly everywhere else on the paper.
