Q

What does the experimental group receive?

A

The independent variable.

17
Q

What is the experimental group?

A

20
Q

What are constants?

A

The variables that are kept the same for each trial.

21
Q

What do constants ensure?

A

23
Q

25
When something is accurate, it is what?
Its close to the value.
26
When something is precise, it is what?
Its close together.
27
When refining, the scientific method is what?
Cyclic.
28
What does cyclic mean?
When steps need to be revisited at any time.
