Question

question 21 of 25
a scientist is planning an investigation to better
understand how bumblebees fly. the scientist plans to
record slow - motion videos of bumblebees in flight to
better observe the motions of the wings.
which type of scientific investigation does this plan describe?
a. comparative investigation
b. descriptive investigation
c. experimental investigation
d. theoretical investigation

Explanation:

To determine the type of scientific investigation, we analyze each option:

• Comparative investigation involves comparing two or more groups/conditions, but here there's no comparison.
• Descriptive investigation aims to observe and describe a phenomenon (like recording bumblebee flight to observe wing motions), which matches the scientist's plan.
• Experimental investigation requires manipulating variables, which isn't done here (no variable is changed).
• Theoretical investigation uses models/theories, not direct observation of the phenomenon.

Answer:

B. Descriptive investigation
