Making Oxygen Botany And Biology Science Experiment
In this fun and easy botany and biology science experiment for kids, we’re going to observe leaves creating oxygen.
- Wide mouth glass jar
- A freshly picked green leaf
- Magnifying glass
- Fill the jar with water.
- Put the leaf in the jar.
- Sit the jar in a sunny location.
- Wait until the jar begins to get warm and then look at the leaf with a magnifying glass.
- Thousands of tiny bubbles will form on the leaf and inside the jar. This is the oxygen being given off by the leaf.
How it Works:
Photosynthesis is the process by which our freshly picked green leaf uses sunlight to make its own food. The leaf used energy from the sunlight to change water and carbon dioxide into oxygen and nutrients called sugars. The leaf can use some of the sugars and store the rest. The oxygen is released into the water as the tiny bubbles we can observe on the leaf.
Make This A Science Project:
Try different types of leaves. Try adding salt to the water. Try blowing into the water with a straw for several seconds before adding the leaf. Try green vegetables like broccoli.
