Question

Henry is interested in studying the different techniques perching birds use to build their nests.

What type of investigation would best help Henry learn more about this topic?
A. perform a controlled experiment
B. make observations in nature
C. discover a previously unknown perching bird species
D. build a model of a nest

Answer 1

I would presume the answer would be (B)since you cannot control a bird and how they make their nests.

Answer 2

Hello Peppa Pig,

I'd say that the answer is B because you can observe how the perching birds make their nests.

Have a good day
