An oil spill is when sea water is contaminated with oil. This can be an accident or human error. Oil spills can be massively damaging to marine wildlife and also humans if the oil gets into the food chain. This hand-on oil spill science experiment is not only great for helping children visualise the effects of an oil spill, but also demonstrates how water and oil don’t mix and why oil floats on water.

Oil Spill Experiment for Kids

Oil dropped onto the surface of water with toy fish #scienceforkids #oilspillexperiment

You’ll need

Clear plastic container

Tray

Vegetable oil

Spoon or pipette

Water

Cotton wool

Cotton buds

Paper towel

Sponge

Oil Spill Investigation Instructions

Step 1 – Add Oil to Water

Half fill the clear container with water. Drop a small amount of
oil onto the water.

The oil will float on top of the water. Even if you shake the
container ( cover it first ) the oil and water will separate again.

Use a cotton bud to move the oil around surface of the water.

Step 2 – Oil Clean Up

Pour enough water into the tray so the surface is completely
covered and the tray is about half full.

Carefully drop two tablespoons of oil onto the surface of the
water.

Experiment with the absorbent materials to discover which cleans
up the oil spill the best.

Oil Spill Challenges

Try to build something to contain oil to one area of the tray.

Try the experiment again, but this time use the same amount of
each absorbing material and collect the oil for the same amount of time. Which
material absorbs the oil the most effectively?

Another idea is to dip a feather in the oily water and watch as it starts to feel heavier. Imagine being a bird with oil covered feathers.  This activity can be further extended by exploring different methods of cleaning oil covered feathers. Water and water with washing up liquid are great things to try first.
