Question

practice it!
a wild duck lays her eggs in the bushes of your front yard. you wonder what effect the temperature outside during spring versus summer has on the mama duck sitting on her eggs until they hatch.
which of the following types of investigations should be performed?
descriptive investigation
experimental investigation
comparative investigation
scientific method

Explanation:

To determine the correct investigation type, we analyze each option:

• Descriptive investigation: Focuses on describing a phenomenon, not comparing groups. This is not suitable here as we are comparing spring and summer temperatures.
• Experimental investigation: Involves manipulating variables (e.g., controlling temperature), but in this case, we can't easily manipulate outdoor temperatures across seasons.
• Comparative investigation: Involves comparing two or more groups (spring vs. summer temperatures) to see their effect on a dependent variable (mama duck's behavior). This fits as we are comparing the effect of different seasonal temperatures.
• Scientific method: Is a general approach, not a specific investigation type for this comparison.

Answer:

comparative investigation
