How to clean up an oil spill
Recently an exciting day was had by all the 'scientists' in Year 5.
We recreated the Exxon Valdez disaster, which happened in Alasksa in 1989. It was one of the largest oil spills ever - an estimated 30-41 million litres of oil spilled. An aea of coastline 2,100 km long was affected. The disaster damaged animals and plants for a very long time.
We poured oil mixed with food colouring in to a container of water, so it looked like an oil spill in the sea.
Then we used different materials to try and seperate the oil from the water.
Our results showed that we couldn't completely clean up an oil spill. Some of the chemicals were left.
