Experimental Design Quiz Flashcards
What does C/E/R Stand for?
Claim, Evidence, Reasoning
The claim is…
Answer to question you’re investigating.
The evidence is…
Date: Charts, graphs, tables. (Easy to understand visually)
The reasoning is…
How the evidence supports the claim.
Independent variable:
One thing that’s being changed/manipulated
Dependent variable:
The data we gather
Control Group
Experimental group without the independent variable
Examples:
Yellow suit placed in front of sun flowers, amount of water given to a plant, amount of medicine given to a patient, sleep a person gets
independent Variables
Examples:
Where the Sun flower faces, how much the plant grows, how much a person’s blood pressure increases, how a student does on a test
Dependent variables
Examples:
Normal sunflower, how much a plant normally grows, a person’s blood pressure normally, the average test score of a student.
Control groups
First step of the scientific method:
have a question, idea, problem, and/or notice something
What should you do after you come up with a question?
Do some research and make a hypothesis
What should you do once you have a hypothesis?
Test your hypothesis (Do experiments and gather data)
What do you do after you test your hypothesis/ gather data?
Analyze the data (Compare numbers, make graphs, annotate)
What do you do after you analyze the data?
Make a decision: Did you make a good hypothesis? If you did, submit for peer review. If you didn’t, go back and make a new hypothesis.
