4. 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.” What do you know about the Gulf Oil Spill? Try to come up with at least three facts. Convert 3 grams to kilograms Convert 10 grams to ounces Convert 7 ounces to mL

6. Oil Spill Lab: Set-Up “The Glory is not in never failing, but in rising every time you faLl”

7. 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?

8. 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!

11. 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

12. 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

13. 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

14. 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: • Scientific Question • Hypothesis • Independent Variable • Dependent Variable • 2 Constants, Control

15. 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 elseon the Lab Rubric and ETO lab template hand out

16. 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

17. Oil Spill Lab – Brainstorm (5 min) • Step 1: In your group brainstorm ways you could remove the oil from the water • What 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?

18. 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?

19. 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

20. 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?

21. 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): • Convert 52 L to mL • Convert 3 tsp to mL • Convert 600 mg to g • Convert .6 g to kg • 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”?
