LIKE OIL AND WATER
Make a rainbow of colours on a patch of oil
RN: 11021703 - CHEMISTRY > ELEMENTS AND COMPOUNDS
1 & 2
Oil and water do not mix because oil has a much lower density compared to water and hence it lies on the top of the water's surface. Use a patch of oil on top of the surface of water to make a rainbow of colours in the following science experiment:
STUFF YOU NEED [MATERIALS]
- VEGETABLE OIL
- NON-STICK PAN
- TAP WATER
- EYE DROPPER
HOW TO PROCEED [PROCEDURE]
- Pour a non-stick pan about 15mm full of tap water from its base.
- Place the pan on a table or flat surface next to a bright sun lit window in your home, but make sure that the pan is not in direct sunlight.
- Hold the pan so that you look into the water at an angle so that the light from the light rays of the sky is reflected in your eyes.
