I am wrapping up my high school level marine science class. I have really enjoyed all the lessons and projects. Today I worked on an experiment about oil spills and different processes to clean them up. 
I had 100ml of oil. I was able to skim off only 30 ml.
The oil soaked into the dirt, feathers and all the water.
I was able to use a dispersant (dish soap) to break up the oil in the water.
Back to class. I should finish this week with the entire class. This is my second high school credit. Not bad for a 6th grader.
