Scientific Inquiry

Question 9 • FL-2003010-M/J Physical Science

Tyler wants to learn about the types of insects in the soil near his house. Which would be a benefit of carrying out a descriptive investigation?

Answer
A
He could collect a large amount of data for a low cost.
B
He could control most of the variables affecting the insects.
C
He would get results that might change after the investigation.
D
He would be able to study cause-and-effect relationships.

Explanation

A descriptive investigation involves observing and recording what is present, such as the kinds of insects in soil. Tyler could sample many spots and record many observations without needing expensive equipment, so collecting a large amount of data for a low cost is a benefit. Controlling variables and identifying cause-and-effect relationships are goals of other types of investigations, not descriptive ones.
