Grassy monsters are fun to grow!

Fall or Spring? In many preschool classrooms, plants and growing are typical springtime activities. Here’s an activity that can add a new perspective by teaching this in the fall—and it  adds a fun twist!

Plastic Cup Monsters
(If the children don’t want monsters, let them draw any character or even themselves on the cup instead.)

What you need:

  • Small plastic cups
  • Markers
  • Cotton balls
  • Small container of water
  • Potting soil
  • Grass seed or radish seeds
  • Eyedroppers
  • Plastic bags

What you do:

Give your child a plastic cup. Supervise carefully while she uses markers to draw a monster (or any other face) on her cup.

Ask your child to dip a cotton ball in the water and place it in the bottom of the cup. Then, put potting soil on top of the balls, stopping 1/4 inch below the cup’s rim.

Help your child sprinkle seeds on top and lightly pat them into the soil. Show her how to use eyedroppers to gently add water to the cup. (Soil should be damp, not wet, or seeds will rot.)

Ask the children to put their cups near a window and put a plastic bag loosely over each cup, like a little greenhouse. Watch carefully as you grow… Monster’s Hair!
