Oil Spill Experimental Organizer: Design your Oil Spill Experiment!!!
You will be learning lots of new words during this activity. Don’t worry; this is just an introduction.
You will have a lot more practice with these words this year. It’s OK if you don’t understand them yet.
The effect of __________________________ on cleaning an oil spill.
Independent Variable: (The thing you test/change)
I chose to test the effectiveness of _________________________________ on cleaning my oil spill.
Dependent Variable: (The thing you measure/ the result) We will all be testing the effectiveness of a different substance on ___________________________.
Control Group: (The set-up that is kept constant/ what you compare your results to) The teacher will be showing the effectiveness of ________________________________ on cleaning an oil spill.
Controlled Variables: (All the variables that must be the SAME in all our set-ups)
How will we know that it is our substance that is absorbing the most oil, and not some other factor?
What needs to be kept the same?
Gathering and organizing data:
Dependent Variable: How will you measure the amount of oil absorbed by your substance? 1. Take the mass of your substance before adding it to the oil. __________g 2. Take the mass of your substance after adding it to the oil. ___________g 3. The amount of oil your substance absorbed = _____g (after) - ______ g (before)
Test Set-up: You will test only YOUR variable. Your teacher will do the control demonstration.
Control = school paper towel Your independent Variable =
Number of Trials 4 4
What you will measure The average amount of oil
absorbed over the four trials
Conclusions: (How will we determine which Independent Variable is the best?) The best independent variable will be the substance that absorbs ____________________________
How will we determine which is the best independent variable for cleaning oil spills in nature?
The best independent variable for cleaning oil spills in nature is ______________________________ _____________________________________________, because ________________________________ _____________________________________________________________________________________
