Big question
• What will be the best sorbent to absorb oil???
I am doing this research to find a better way
to clean up oil spills.
2
3
Hypothesis • I think that the polymer will be the best
sorbent to absorb the oil. I think this because
polymer is a sorbent that absorbs things really
well.

hypothesis

Fun Facts!!!• #1…oil spills happen all the time!
• #2…it can take months to clean up…because
they have to clean the ocean as well as the
animals involved.• #3…if an oil rig blows up many gallons of oil will
flow into the ocean.• #4…when an animal is involved in an oil spill like
a bird that bird won’t be able to go any where
that is because the oil is to heavy on it’s wings. 4

More fun facts!!!!!
• #5…all the oil from an oil spill might sink to the
bottom before the clean up crew can get to it
so that causes clean up to last even longer
because they have to clean it up from the
bottom of the ocean.
• #6…most clean up crews are volunteers but
some are trained people

materials• Large plastic garbage bag• Liquid measuring cup,4-cup size• Four sorbents(3 cups of each)• Newspaper-easy cleanup• Polymer• Cotton balls• oat meal• Shop Towels• Gloves• Eye protection

materials• Scissors, if sorbent needs to be cut into smaller pieces• Paper or glass bowls, 12-oz size (you need 3 bowls for each
sorbent )• Vegetable oil(1 gallon)• Water(1 gallon)• Dry measuring cup, 1-cup size• Single-serving mesh micro-screen coffee filters, should fit
easily inside liquid measuring cup• Stopwatch• Liquid soap• Lab notebook or laptop• Graph paper

procedures
• #1.Spread newspaper onto your work surface• #2.Open your garbage bag and put it close to
the measuring cup.• #3.Prepare and test your sorbents one at a
time so you can keep your work space uncluttered. Large sorbents must be cut into small, thumbnail-sized pieces so that they can fill a measuring cup. wear eye protection and gloves.

procedures
• #4.After you've prepared your first sorbent and placed each sorbent in a glass or paper bowl.
10
procedures
#3 place each pile in a glass or paper bowl. • #5.Make a data table in your lab
notebook for each sorbent, as shown below for Sorbent 1, to record the results.
• Polymer• Total Water and Oil Level
(A)

11
procedures
• Remaining Water Level After Removing Sorbent(B)
• Remaining Oil Level After Removing Sorbent(A-B)
• Ratio = (Remaining Water) / (Remaining Oil)• Polymer bowl #1
11
12
procedures
• Polymer bowl #2 • Polymer bowl #3• #6.Pour 3 cups of water into the liquid
measuring cup.
12
13
procedures
• #7.Slowly add 1 cup of oil. Do the oil and water separate or mix? Note: In some trials, a layer of bubbles may form between the water and oil layers. If this happens, then you must dump out the water and oil mixture and start with fresh ingredients since it will be too difficult to measure where one layer begins and the other ends. Alternatively, you can wait until the bubble layer disappears.
13
14
procedures
• #8.Put 1 cup of your first sorbent into the micro-screen filter. Lower it slowly into the water-oil mixture and gently move it from side to side for a few seconds until the sorbent is completely submerged.
• #9.Start the stopwatch. • #10.After 30 seconds, lift the filter with the contents
of the sorbent inside and hold it just above the surface of the water-oil mixture for 30 more seconds to drain.
14
15
procedures• #11.Dump the contents of the mesh strainer into the plastic garbage bag. • #12.Get down level with the liquid measuring cup and read and record the
total water and oil level.• #13.Measure and record the remaining water level. • #14.Wash out the micro-screen filter with soap and water. • #15.Add water and oil until your measuring cup once again shows 3 cups
of water and 1 cup of oil. Note: It is not necessary to start with fresh water and oil each time (steps 6 and 7) unless a layer of bubbles has formed between the water and oil layers.
• #16.Repeat steps 8–15 for the remaining piles of your first sorbent. • #17.Then proceed with steps 4–15 for the rest of the sorbents you chose.
Again, it is not necessary to perform steps 6 and 7 again, unless a layer of bubbles has formed between the water and oil layers.
15
16
procedures
• #18.Now calculate the remaining oil after removing the sorbent (A - B) for each trial and record it in your data table.
• #19.Calculate the ratio of remaining water to remaining oil for each of the trials and record it in your data table.
• #20.Average the ratios for each sorbent and record them in a new data table, as shown in the table below:
• Sorbent Name• Average Ratio of Water to Oil• No Sorbent• 3• Polymer• Cotton• Straw • Shop Towels
16
17
variables
• #1…oil• #2…polymer• #3…oat meal• #4…cotton balls• #5…shop towels

observations
Before any sorbent had been added.
After oat meal had been added and removed.
After cotton balls had been added and removed.
After shop towels had been added and removed.
After polymer had been added and removed.

Analysis of data
• A…they experiment did test my hypotheses.• B…I know that because not only does polymer
absorb things very well and in most oil spills polymer helps a lot!!!
21
conclusion
• A… my hypothesis was not correct.• B…I would change the amount of oil, water,
the type of oil, and the type of water.• C…my new question is what is polymer made
of???? How does the polymer work???
