Catalyst Take out your lab notebook with completed Oil Spill Lab set-up. Review your procedures and make sure that you have a plan for each of the following:  How you will test your technique including: how your cleaning device will move, where it will be in the oil, and how long you intend to use it for  Measurement of the amount of oil extracted (or how long it took to extract the oil—whatever your dependent variable is)  I will need to see Problem Statement, Hypothesis, Variables, Materials and Procedures before you can begin your experiment

“THE GLORY IS NOT IN NEVER FAILING, BUT IN RISING EVERY TIME YOU FAIL” Oil Spill Lab: Experiment

Objective and EQ Objective:  SWBAT explain the process of scientific inquiry and apply this thinking to solve a real-world problem. (1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.2.1).  SWBAT design and perform an experiment (1.6.1, 1.4.2, 1.4.3) Essential Question:  How can we apply the scientific method to clean up a real-life Oil Spill?

Lab Procedures, Set-Up, and Expectations Safety Precautions Acquiring Materials Measurements Recording Data Disposing of Materials

Pre-Lab Discussion Do you foresee any problems in measuring oil, using your technique, or disposing of materials? Assign Lab Roles. Every group must have:  Project Manager  Materials Manager  Technical Director  Safety Director Record these at the top of your lab

Catalyst – Make sure you have the following: Problem Statement – must explain what you are testing, NOT a yes or no question  Ex, what is the most effective material to clean up an oil spill? Hypothesis – If…then…because…  Ex, If I use and sponge and a paper towel to clean up the oil spill, then the sponge will clean up more oil because it is porous Variables – IV, DV, Control, Constants  IV – what are you manipulating or changing?  DV – what are you measuring? Changes because of the IV  Control – baseline for comparison, what if you did nothing?  Constants – type of sponge, amount of oil/water, etc Materials – What supplies will you use? Procedures – List the steps you will take to test your hypothesis

Performing the Experiment Complete your procedure as listed. Please remember to record any changes or problems with procedures and record all data in a table! Questions to consider while you work:  Are you encountering any problems with your procedure? If so, write them down!  Do you think you are recording reliable data? What might make your data unreliable?  If I wanted to repeat your test using your procedures and nothing else, could I do so?  Would you trust your data if it came from another group?

Compiling and Analyzing Data Clean-up any oil-soaked materials and dispose of any excess water and oil as directed. Return to your seats. Add Class Data to the data you acquired. Record only the data that measures the same Dependent Variable you studied. Do you see any trends in the data? Did any techniques work particularly well? Did any techniques have particular problems?

Data Analysis: Sample Data Method of CleanupAmount of Oil Recovered (mL) Sponge with Filter13mL Sponge with String9mL Filter Only (5 seconds on bottom)6mL Scrap Paper with Filter8mL Notes:  If you don’t have the same units, you can’t compare data.  Don’t compare a first trial to a second trial.  Offer a small description of the method Do you see any trends in the data? Did any techniques work particularly well? Did any techniques have particular problems?

Sample Chart

Conclusion Writing In your groups, review the ETO Conclusion Writing Format as Ms. Hagan models it at the board. Key Points: Minimum 3 paragraphs First: Intro– Describe problem. Was your hypothesis supported? Middle: Discuss findings and compare results to other student data. Final: Explanations for your findings, recommendations for future study, possible applications.

Lab Wrap-Up How can we apply the scientific method to clean up a real-life Oil Spill? Successes? Problems? Next Lab: Density Check out the class website under the ‘Labs’ tab to see the grading rubric, ETO template and oil spill documents
