Invisible Skin

Have you ever wondered how polar bears are able to survive when they are swimming in the freezing cold waters of the Arctic? We are going to explore the simple fact that water and oil do not mix in a fun and easy science experiment called invisible skin.

Little Passports

Check it out in action!

 

What you will need:

Simple Science Experiment for Kids- Invisible Skin

4 to 6 drops of vegetable oil

water

liquid or bar soap for hand washing

journal

pens and crayons

 

Result Timing:

10 minutes

 

What to do:

  1. First holding your hands over a sink put about 4-6 drops of oil into one hand and then rub your hands together.
  2. Next, turn on the cold water and let the water run over your hands. What happens when the water touches the coating of oil on your hands?
  3. Write down your answers in your journal, draw a picture of what your hands look like.
  4. Next, rub some soap into your hands and put them back in the water. What happens when the water touches your clean hands?
  5. Write down your answer in your journal, draw a picture of what your hands look like now.

How it works

Water is made of extremely tiny pieces called molecules. The molecules of water stick together very tightly. The molecules that make up oil are arranged differently from water molecules, so when they’re put together, the oil molecules won’t easily dissolve into the water. You probably noticed that the water rolled off your oily hands (the oil being the “invisible skin”) rather than washing the oil off with it, the water molecules stick to other water molecules rather than grabbing onto the oil molecules. So that is why polar bears don’t mind swimming in the freezing water. Their fur is very oily and so it acts as a kind of waterproof coat to keep the water away from their skin.
