Why not use natural resources l.jpg
Why Not Use… US!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 l.jpg
Your Task for Today US!

  • Conduct an experiment using a Physical/Mechanical Method of oil clean-up!

  • Determine which natural resource works the best for absorbing an oil spill!


Scientists use models to test their hypotheses l.jpg

Natural resources l.jpg
Natural Resources: US!

  • Cotton

  • Chicken Feathers!

  • Sawdust

  • Peat Moss and Spanish Moss

  • Perlite

What is your HYPOTHESIS?


Rating the different materials l.jpg
Rating the Different Materials US!

We will Rate TWO QUALITIES of the different materials:

  • Their ability to absorb oil

  • Their ease of use


Our rating scale l.jpg
Our Rating Scale US!

  • 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 l.jpg
Clean-up Procedure US!

  • 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 l.jpg
Experimental Design US!

  • Title

    • Which natural resource will clean-up oil best?

  • Hypothesis

    • I hypothesize that the _______ will absorb oil the best.


  • Experimental design24 l.jpg
    Experimental Design US!

    • Independent Variable

      • Type of natural resource

  • Methods

  • Trials (#)

    • # per group or # per class


  • Experimental design25 l.jpg
    Experimental Design US!

    • 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…
