Annabelle loves to learn about plants. for a class project, she thought of the following question:
do plants enjoy it when people sing to them?
this question is
a. a valid scientific question because it is about plants.
b. not a valid scientific question because it is not testable.
c. not a valid scientific question because it is about plants.

THE ANSWER IS: not a valid scientific question because it is not testable.

Good scientific questions must be testable, and they can be answered using data and facts obtained from research, observations, or experiments. Good scientific questions do not ask about opinions or emotions.

"Do plants enjoy when people sing to them?" is not testable because it is not possible to ask a plant whether it enjoys something or not. Therefore, Annabelle's question is not a valid scientific question.

A possible, valid scientific question on this topic is "Do plants grow faster when people sing to them?" This question is valid because it is testable, and it does not ask about emotions.
