The dependent variable
Variable that is graphed on the Y axis
Dependent variable
The factor that is measured; experimental outcome

The amount of time it takes for the glassware to air dry.
A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes. The dependent variable is_____
The amount of pressure on her feet
In an experiment to see how far footballs go when the type of gas used to fill them is changed, the independent variable is____
The type of gas used to inflate the footballs

Your testable question. (How does the IV effect the DV?)
Factor kept the same throughout the experiment
Constant or controlled variable
Billy wants to see how the temperature of the water used to clean glassware affects the amount of time it takes for the glassware to air dry. Name two possible constants.
The type of water, the type of glassware, the type of soap, the amount of soap, the amount of scrubbing, the temperature of the surrounding room, the amount of air flow, the surface on which the glassware is set
A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes. The independent variable is_____
The type of material in the shoe
An experiment is done to test what home treatment keeps trees healthier longer. All of the trees get the same amount of water. The amount of water is the _________.
controlled variable
In our paper towel experiment what was the label of our x axis?
The brand/type of paper towel (the independent variable).
Cutting the paper towels to make them the SAME size is an example of a
Controlled variable
Billy wants to see how the temperature of the water used to clean glassware affects the amount of time it takes for the glassware to air dry. What would a reasonable hypothesis to this experiment be?
The warmer the water, the faster it will dry
A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes. Name two controlled variables or constants.
The size of the shoe, the surface on which they're worn, the amount of time en pointe, the area on which weight is applied, the weight of the dancer
In a CER report the C stands for claim. The claim is the...
Answer to the question.
For example: We claim the singer with lots of cats is Taylor Swift.
In our paper towel experiment what was the label of our y axis?
The amount of water absorbed (our dependent variable)
Why does an experiment need controlled variables?
To make the data reliable by keeping the experiment fair.
Billy wants to see how the temperature of the water used to clean glassware affects the amount of time it takes for the glassware to air dry. What information should go on each axis of the graph of the data?
The temperature of the water should be on the X axis, the amount of time it takes for the glassware to air dry should go on the Y axis.
A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes. What should be graphed on the Y axis?
The amount of pressure on her feet.
In a CER (Claim Evidence Reasoning) this the the part where we share our data.
