Separating
Environmental Mixture of Oil & Water
Purpose:
In this experiment I will investigate different methods
of removing oil from water.
Hypothesis:
If I use cotton balls to soak up the oil, then I think…
If I use a medicine dropper to suck up the oil, then I
think…
If I use a straw to move the oil to one corner, then I
think…
If I use drops of detergent to the oil, then I think…

Conclusion:
What did you learn about separating oil from water?
What environmental impact would an oil spill in the ocean have?
How accurate was your hypothesis?
I will bring in all the necessary materials for the above mini lab

Paul’s first 5 tosses were (-1) + (-1) + 1 + 1 + 1 with
a total score of 1 since the dotted line on his graph begins at (-1) and ends at +1
after 5 tosses.
My first 5 tosses were ________________________ with a
total score of _____ since the dotted line on my graph begins at ____ and ends
at ____ after 5 tosses.
After 20 tosses, Paul’s final score is ______.
After 20 tosses, my final score is _______.
Our results are similar because…
Our results are different because…
I noticed that when the value of the toss is +1 the
total score…
I noticed that when the value of the toss was -1 the
total score…
If I repeated the experiment with 50 coin tosses then I
think the greatest possible total score would be…
If I repeated the experiment with 50 coin tosses then I
think the least possible total score would be…
