Make A Rainbow Water Science Experiment
In this fun and easy water science experiment, we’re going to make a rainbow.
- Baking pan
- White piece of paper
- Fill the baking pan three quarters of the way full with water.
- Find a sunny spot.
- Place the mirror in the water and lean it against the edge of the baking dish.
- Now direct the mirror’s reflection onto the white piece of paper.
- You will see a rainbow of colors.
How it Works:
When the white sunlight shines into the water it bends. White light is a combination of all the visible colors. So when white light bends, all of its parts also bend. These parts or colors (red, orange, yellow, green, blue, indigo, and violet) all bend at a different angle because each of the colors travel at different speeds in the water. When the mirror reflects the light back out of the water it has been broken up from refraction into the full rainbow of colors that you can see on the piece of white paper.
Make This A Science Project:
Try this experiment using a flashlight. Try this experiment with colored light. Try using crumpled aluminum foil instead of a mirror. Try coloring the water.
