  9. How Would YOU Clean-up an Oil Spill? Photo by EPA

  10. Methods of Clean-up • Biological • Chemical • Physical (or Mechanical) Photo by EPA

  15. Why Not Use…NATURAL RESOURCES! • Occur naturally or are natural by-products • Are readily available • Do not harm the environment • Are they effective? Which is best?

  16. Your Task for Today • Conduct an experiment using a Physical/Mechanical Method of oil clean-up! • Determine which natural resource works the best for absorbing an oil spill!

  17. Scientists Use MODELS toTest Their Hypotheses Photo by N. Hamm

  18. Natural Resources: • Cotton • Chicken Feathers! • Sawdust • Peat Moss and Spanish Moss • Perlite What is your HYPOTHESIS?

  19. Rating the Different Materials We will Rate TWO QUALITIES of the different materials: • Their ability to absorb oil • Their ease of use

  20. Our Rating Scale • We will rate the absorbency and the ease of use of each material by this scale: 1 = Good 2 = Fair 3 = Poor

  21. One Team’s Results Photo by A.C. Lundberg

  22. Clean-up Procedure • Dump out pan into strainer in sink. Rinse out pan. • Wipe off utensils (fork, forceps…) and return to kit. • Close all materials bags and return to kit. • Throw away newspaper and material testing sheet. • Wipe off lab table.

  23. Experimental Design • Title • Which natural resource will clean-up oil best? • Hypothesis • I hypothesize that the _______ will absorb oil the best.

  24. Experimental Design • Independent Variable • Type of natural resource • Methods • Trials (#) • # per group or # per class

  25. Experimental Design • Dependent Variable • Amount of oil absorbed • Ease of use • Constants • Amount of oil, Time to absorb oil, amount of material, type of oil, boom materials…
