Question

Ben bought two identical plants and placed them on opposite ends of his garden. After several days, he noticed that one grew taller than the other. Ben wants to conduct an experiment to see why one would grow more than another.

observation

hypothesis

scientific question

experimentation

Answer 1

Ben is in the observation phase. Noticed something unusual, that he would like to know more about.

He has not yet formed a hypothesis to explain why one plant grew taller than the other. Ben needs to do some more observation of the conditions around the plants and their history, to see if he can something that might be the reason for the difference.

Then he can form a hypothesis.
