Kids Science Experiments - Can Water Bend a Pencil?
Bending Light Experiment
Bending Pencil
Materials you will need:
• Pencil
• Water
• Clear Glass or JarLight can play tricks on your eyes!
This is a very fast and easy experiment.
Steps:1. Fill the glass or jar half way with water.
2. Place the pencil in the water.
3. Look at the pencil from the top.
4. Look at the pencil from the bottom
5. Look at the pencil from the sides.Straight or bent? What happens when you look at the pencil through the side of the glass? Light play tricks on your eyes. The pencil looks bent. This is because light travels slower through water than through air. As the light enters the glass of water it slows down(changes direction) and as it leaves the glass it speeds up again – therefore making the pencil look bent!
