The students tested their device twice using the bowl of water with oil. They modified their design between the first and second tests. The procedure and results of each test are described in the table.

Identify at least two problems with the device and the procedure. How should the students modify their solution to correct these issues?

Do you think scientists could use the students' device on a larger scale to effectively clean up oil spills? Explain your answer.

Research two methods commonly used to clean up large oil spills. Based on the results of the students' experiments, what are the strengths and weakness of each approach?
