Oil spill clean up lab
To prepare the fresh liquid:
- Fill baking meal with cool tap water within one cm of rim.
- Include five-six drops of meals dye.
- Combine dye and liquid with a stirring pole. Let option settle.
To simulate the sea liquid:
- Fill cooking meal with cold-water within 1 cm of rim.
- Add 8 teaspoons of salt slowly and stir until dissolved.
(If you have a hygrometer, keep including salt until you get to a salinity of 1.024 – 1.026.)
- Add five to six falls of food dye.
- Mix dye and “ocean liquid” with a stirring pole.
To simulate crude oil:
- Place 3 Tbsp. of vegetable oil in mug.
- Add 2 Tbsp. of cocoa powder.
- Mix cocoa dust and oil completely with a paddle pop music stick.
To contaminate each fresh-water and sea water container:
- Extremely gradually pour simulated crude oil from a height of just one cm onto the the surface of the fresh-water meal. If you afin de the oil too quickly, the test won’t work.
- What occurred to the oil once you dropped it in the fresh-water? Made it happen sink? Float? Combine in?
- Perform actions 1-3 with ocean water.
To check the sorbents:
- Spot a tiny sorbent sample in to the center the surface of the contaminated fresh-water.
- Record your findings in dining table 1. Consist of all the following information:
a. Simply how much oil performed the sorbent tidy up? Exactly how quickly?
b. Does the sorbent pick up liquid also? In that case, how can you tell?
c. Does the sorbent sink or float?
d. What is the condition associated with the polluted sorbent?
- Remove sorbent with tweezers or tongs.
- Remove polluted fresh-water.
- Create brand-new polluted fresh-water following same treatment as prior to.
- Include detergent toward oil-contaminated fresh water.
- Just what happened as soon as the detergent was added to the polluted liquid?
- In which would the oil go in “real” fresh-water after a dispersant (like dishwashing detergent) is used?
- How clean could be the fresh water now that this has dishwashing liquid inside it?
- Perform measures 1-7 with sea water and compare the outcomes with those for fresh water.
To ascertain how oil affects feathers:
- Dip feather into oil-contaminated fresh water.
a. What are the results when a feather gets oil onto it?
b. Just how might an oiled feather affect a bird?
- Repeat the actions above, substituting sea water for fresh-water.
To determine exactly how oil affects soil:
- Make use of five plastic petri dishes.
- Fill one petri dish with fine-grained sand.
- Fill one petri meal with medium-grained sand.
- Fill one petri meal with coarse-grained sand.
- Fill one petri dish with “mud” created by adding enough water to potting soil to create a paste.
- Fill one petri dish with dry potting soil.
