Catalyst
“The Gulf of Mexico Oil Spill (aka the Deepwater Horizon Oil Spill) flowed unabated for three months in 2010, and may be continuing to leak. It is the largest accidental marine oil spill in the history of the oil industry.”
1. What do you know about the Gulf Oil Spill? Try to come up with at least three facts.
2. Convert 3 grams to kilograms3. Convert 10 grams to ounces4. Convert 7 ounces to mL

Oil Spill Lab: Set-Up
Objective and EQ
Objective: SWBAT explain the process of scientific inquiry and apply this thinking to solve a real-world problem.
EQ: How can we apply the scientific method to clean up a real-life Oil Spill? What are the expectations for Essential Lab Reports?
The Gulf Oil Spill
Background Information: http://www.nytimes.com/interactive/2010/05/01/us/20100501-oil-spill-tracker.html
Scientists have come up with many strategies to help combat the spill.
These attempts all rely on the scientific method!
Gulf Oil Spill Cleanup
Problem: How can we best clean up the oil protect the environment?
Hypothesis: If we use a plug, then we can keep the oil from harming the environment, because the oil won’t be able to keep leaking out.
Experiment: Try it. Record Data.
Data Analysis: Did it work?
Conclusion: Using a plug was not very effective. We need to try something else.
Parts of an Experiment
Scientific question – cannot be a yes or no question, includes the independent and dependent variables
Hypothesis – If…then…because… If I do this…then I predict this will happen…because…give scientific reason why you think your prediction will happen
Independent variable – What are you manipulating in the experiment? What are you changing from trial to trial?
Dependent Variable – What are you measuring in this experiment?
Constants – What doesn’t change in the experiment? What factors are you keeping the same?
Control – the baseline, what you compare your results to
We Do
Another example: Shontae put a water bottle filled with water into the freezer and left it overnight. The next morning, she discovered a crack in the bottle. Design an experiment to investigate why this happened. Identify the following: Scientific Question Possible Hypothesis Experiment:
Independent Variable Dependent Variable 2 Constants, Control
We Do
Another example: Ed watered his grass with salt water. When he woke up the next day, he saw that all of his grass was dead. Design an experiment to investigate why this happened. Identify the following: Scientific Question Possible Hypothesis Experiment:
Independent Variable Dependent Variable 2 Constants, Control
We Do
Another example: Two groups of rats were used for an experiment. Group A was kept in a cage that had a running wheel. Group B was kept in a cage with nothing in it. The rats in Group A did better on memory tests (like running through a maze) than the rats in Group B. Identify the following:

Lab Notebooks!
What I must see for every lab: Cover page Title Group Members and Roles Introduction (5 sentence) Problem Statement and Hypothesis Materials and Procedures Data and Data Analysis Conclusion (3 paragraph) Anything else on the Lab Rubric and ETO lab template
hand out
Oil Spill Lab
You need to remove the oil from the water (and measure and plot how much oil you removed) using the materials at the front of the room
By the end of class you will need to have a problem statement, hypothesis (includes IV and DV), materials list, procedure and identify the variables bad hypothesis – If I use a sponge to clean up the oil,
then the sponge will be able to absorb oil because it is absorbent
GOOD hypothesis – If I use different sized sponges to clean the oil spill, then the larger sponge will absorb more oil because it has a greater surface area
Oil Spill Lab – Brainstorm (5 min)
Step 1: In your group brainstorm ways you could remove the oil from the waterWhat materials will you use?How will you use the materials?What is your comparison? What are you testing or trying to prove with this experiment?
Oil Spill Lab – Form Experiment (10 minutes)
Formulate a Scientific Question/Problem Statement.
Formulate a hypothesis This must have an IV and DV. If I do this….Then I
predict this will happen…because (give scientific explanation)
Identify your variables Independent Variable – What are you changing? Dependent variable – what are you measuring? Control – 20 mL of oil initially in the water, point of
comparison Constant – what is NOT being changed?
Oil Spill Lab – 15 min
List your procedures and materials. Be as specific as possible.
Finish first page of the ETO lab template in your lab notebook. Include: Cover page Title (with IV and DV) Introduction (background info, 5 sentences) Problem Statement Hypothesis Materials Procedures Variables
Recap Questions
What role does science play in solving real-world problems?
How does the scientific method relate to efforts to clean up the Gulf Oil Spill?
What are some solutions we came up with?
Extension Question: Do you think scientists deserve acclaim for their efforts? Why or why not?
Home Learning
If you did not finish either the Problem Statement, Hypothesis, or Procedures section, complete this for homework.
Regular Problems (all students must complete):1. Convert 52 L to mL2. Convert 3 tsp to mL3. Convert 600 mg to g4. Convert .6 g to kg5. The conversion factor “1 g = 1000 kg” can be
written as: or . What are the two ways you could write the conversion factor “1 mL = .035 oz”?
