Today we did a feather and oil experiment.
We had cold water, hot water, soapy water and room temputure water.
I had one of the three types of feathers.
We dunked them in oil and tried to rinse it out in the waters but the oil didn't come out.
After a while it came out I put it some water and it separated the individual parts of the feather.
Then I put it in some hot water and it went back to normal.
It was fun predicting how it would work.
The picture below, shows the effects of oil on seabirds. Oil kills!
