Science Experiment Oil and Water

In this science experiment, oil and water are studied and their ability to mix together is tested.

Theory of science experiment - oil and water

Oil and water do not mix. Ducks keep their feathers waterproof by spreading oil from a special gland onto their feathers.

In this science experiment, oil and water are mixed together and observed.

What you need to conduct a science experiment of oil and water?

For this science experiment of oil and water, very little is needed. You need:

• a little cooking oil
• water
• a jar
• a few drops of dish washing liquid

The science experiment of oil and water

• Put a little cooking oil and water in a jar.
• fix the lid on firmly.
• Shake the jar hard
• Put the jar down.

Result of the science experiment of oil and water

You will see that oil and water will separate into two layers. This indicates that oil and water do not mix.

Now, for the second par of science experiment of oil and water:

• Add a few drops of dish washing liquid.
• Shake the jar again

Result of the science experiment of oil and water

This time, a cloudy mix is formed. How did it happen? The soap in the dish washing liquid breaks up the oil into small drops which hang in the water and make it look cloudy. This is how dish washing liquid removes grease from plates, pots and pans.
