Respiring Plants is an easy gardening activity that teaches kids how plants breathe.What You'll Need:
- Leafy plant
- Petroleum jelly
Step 1: Even though plants don't have nostrils or mouths like people do, they still need to take in air. There's a way to find out how plants breathe. Just take a small plant that has plenty of leaves and place it on an outdoor windowsill.
Step 2: Cover the tops (not the bottoms) of five of the plant's leaves with a thick coating of petroleum jelly. Then, cover the bottom sides only of five other leaves with another thick layer of jelly.
Step 3: Make a chart and keep track of how each leaf looks every day. Watch your plant for a week, and see if you can figure out which side of the leaf needs to be uncoated in order to bring in fresh air.
