Year 5 Oil on water investigation

11 June 2014

As part of our topic work we have been looking at coastlines and beaches. We found out that a significant amount of damage is caused to beaches and sea life because of oil spills at sea.
We set up an investigation to find out the best way of dealing with an oil spill. We made a saline solution and used a pipette full with oil to create an ‘oil spill’. We looked at 3 methods for removing the oil: dispersal (detergent), absorption (sawdust) and sinking (flour). The 4th cup was our constant so we could monitor what happens to oil if it is just left. We made predictions about which method would be best for removing the oil and tested our predictions. We found out that absorption is the best way to clean up an oil spill and is also best for the environment.
