Science Experiment

Reduce Friction

In this easy experiment, we are going to observe leaves creating oxygen

What You Will Need

• Wide mouth glass jar
• Water
• A freshly picked green leaf
• Magnifying glass

Instructions

1. Fill the jar with water.
2. Put the leaf in the jar.
3. Place the jar in a sunny area.
4. Wait until the jar begins to get warm and then look at the leaf with a magnifying glass.
5. Thousands of tiny bubbles will form on the leaf and inside the jar. This is the oxygen being given off by the leaf.

What Is Happening

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 observe on the leaf
