why not use natural resources
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?
your task for today
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!
natural resources
Natural Resources:
  • Cotton
  • Chicken Feathers!
  • Sawdust
  • Peat Moss and Spanish Moss
  • Perlite

What is your HYPOTHESIS?

rating the different materials
Rating the Different Materials

We will Rate TWO QUALITIES of the different materials:

  • Their ability to absorb oil
  • Their ease of use
our rating scale
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

clean up procedure
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.
experimental design
Experimental Design
  • Title
      • Which natural resource will clean-up oil best?
  • Hypothesis
      • I hypothesize that the _______ will absorb oil the best.
experimental design24
Experimental Design
  • Independent Variable
      • Type of natural resource
  • Methods
  • Trials (#)
      • # per group or # per class
experimental design25
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…
