What is capacity/volume?
A conclusion based on observations.

What is Data?
What is control variable/control group?
This is how you write a hypothesis.
What is If, Then, Because?
What is share your results?
A step-by-step instructions for completing a task.
What are procedures?

What are the students that don't get Sparkens.
A valid experiment must be able to be this.
What is replicated?
When doing an experiment, we only want to test this amount of variables at a time.
What is one variable?
