21. OIL SPILL CLEAN-UP

How can we clean up after an environmental disaster?

You will need

A 1-litre container

Water

Vegetable oil

A teaspoon of cocoa powder

Feathers

Cotton wool balls

A plastic cup

A sponge

A plastic spoon

A timer

How to do it

Note: To minimise mess, wear appropriate clothing and conduct this activity outside.

Mix the water and oil in the container in a ratio of around 4:1. Mix in the cocoa powder and add the feathers.

There has been an environmental disaster! Imagine this container represents the sea after an oil spill and use the equipment provided to remove as much of the oil as possible into the plastic cup. You have 15 minutes. Each feather represents a marine animal that must be cleaned up.

Time is up! Measure how much oil is in the plastic cup, and how many feathers have been cleaned. How successful was the clean-up challenge?
