His teacher tells him that dish soap is safe and effective in cleaning the oil off of birds. Conrad uses two pans of water to model the ocean. He adds oil to one pan. How can Conrad use dish soap with his model to study how adding dish soap to oil spills would help protect water birds from the oil?

Question

A.
Add dish soap to the second pan, then place them both outside to see which one birds would rather drink from.
B.
Add oil to the second pan, add dish soap to it, then dip one feather in each pan.
C.
Add oil to the second model, add dish soap to it, then wash one dish in each pan.
D.
Mix dish soap into the second pan, then add oil on top of it.

Answer 1

Conrad can use option B: Add oil to the second pan, add dish soap to it, then dip one feather in each pan.

This method allows Conrad to directly compare the effects of oil and dish soap on a feather, which simulates how dish soap can help clean oil off of birds. By examining the differences between the two feathers, he can better understand the effectiveness of dish soap in treating oil spills affecting water birds.
