Extra Activity:

How a Cactus Stores Water

Using paper towels and wax paper, this simple activity shows students how the thick, waxy stems of cactus or the thick leaves of a succulent hold water.

If you have access to any succulents, bring in a few stalks and leaves. Let your students slice the leaves open and see the moist interior.

Extra Activity:

A Plant with a Water Tank

The bromeliad, a plant that lives in the rainforest, avoids the shade of the forest floor by growing on the branches of tall trees. Living high in a tree, the bromeliad can't get its roots into the ground. So it stores water in a bowl made of its waxy leaves. This water tank is home to frogs, as you can see in this video.

The pineapple is a kind of bromeliad that you can grow and experiment with in your classroom. Find out how at this site from the Rain Forest Alliance.

Art Extension: Grassheads With Style

At Mystery Science, we couldn't resist adding a bit of style to our grassheads. If your class would like to do the same, you'll find plenty of inspiration online. Your grasshead could wear pigtails, a mohawk, or a cute little bow. You can add googly eyes, pipe cleaner eyeglasses, and paper clothes. With a simple makeover, you can make your grasshead into a star! The possibilities are endless.

Here are supplies you may need:

  • pipe cleaners (for eye glasses)
  • peel-and-stick googly eyes
  • construction paper for "clothes"
  • ribbons for hair bows
  • scissors for grasshead barbers and stylists
