Mary is conducting her experiment using the scientific method. She is currently planning how she will carry out the experiment and which tools she will use. Which steps did she complete before this step?

Question

A
Asking a scientific question

B
Developing a hypothesis

C
Form a conclusion

D
Both a and b

Answer 1

The correct answer is D: Both A and B.

Before Mary starts planning how she will carry out her experiment and which tools to use, she would have first asked a scientific question and then developed a hypothesis based on that question. The conclusion comes after conducting the experiment, so it would not be a step completed before this stage.
