CER
A statement that answers a focus question or problem.
Claim
TRUE or FALSE
You are allowed to eat and drink while doing an experiment.
FALSE
How many centimeters (cm) are in 1 meter (m)?
100 cm
A __________________ ________________________ is a scientific investigation in which there is an independent variable, a dependent variable, and all other factors are kept constant.
Controlled experiment
The variable that is purposefully, or intentionally, changed by the scientist during a controlled experiment.
Independent variable
Support for the claim in the form of data or observations.
Evidence
TRUE or FALSE
Long hair should be tied up during an experiment.
TRUE
Convert 6 hectograms (hg) to grams (g)
6 hectograms (hg) = 600 grams (g)
If one variable increases as the other variable increases, this is known as _______________ correlation.
Positive
The variable that the scientist measures, or thinks might be affected, during an experiment.
Dependent variable
How or why the evidence supports the claim AND a scientific definition or idea that supports the claim.
Reasoning
What technique would we use to determine if a substance has an odor?
Wafting
How many milliliters (mL) are in 1 kiloliter (kL)?
1 kiloliter (kL) = 1,000,000 milliliters (mL)
If there is no obvious relationship between two variables on a graph, this is known as _________________ correlation.
The factors in a controlled experiment that are not changed so that they don't affect the outcome.
Constants
The statement: "As the number of glycerin drops increased from 0 to 30, the average diameter of the bubble increased from 3.3 to 4.3" is an example of claim, evidence, or reasoning?
Evidence
Tell the teacher
How many decimeters (dm) are in 2.57 decameters (dam)?
2.57 decameters (dam) = 257 decimeters (dm)
If one variable increases as the other variable decreases, this is known as _______________________ correlation.
Negative
To make an educated guess about the outcome of a situation.
Predict
The statement "The paper in the cup with no hole did not get wet because the air took up space and blocked the water. Volume is the space occupied by an object." is an example of claim, evidence, or reasoning?
Reasoning

0.0623 kilometers (km) = 62300 millimeters (mm)
