Plants have amazing power, as this garden activity for kids shows. You might think that rocks would be stronger than plants, but plants are strong enough to break through rock. This experiment will show you how strong plant power can be.
What You'll Need:
- Plaster of Paris
- Aluminum-foil baking pan
Step 1: Soak a handful of beans in water overnight.
Step 2: Pour plaster of Paris into the aluminum foil baking pan. The plaster of Paris should be a couple of inches deep.
Step 3: Sprinkle the soaked beans on top.
Step 4: Cover the beans with another layer of plaster of Paris about an inch thick.
Step 5: Watch what happens. When the beans sprout, they will break right through the rock-like plaster of Paris.
You can see examples of this in nature. When you go for a walk, look for plants and trees growing up through rock, or tree roots breaking up a concrete sidewalk.Imagine playing in a leafy fort topped by big yellow flowers. Keep reading to learn how you can make a sunflower fort in your backyard.
