Factor that is graphed on the Y axis

Dependent variable

### 200

The factor that is measured; experimental outcome

Dependent variable

### 200

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.  The DV is____

The amount of time it takes for the glassware to air dry.

### 200

The amount of pressure on her feet

### 200

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

### 300

the way to write a proper graph title

"The effect of IV on DV"

### 300

Factor kept the same throughout the experiment

Constant

### 300

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

### 300

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

### 300

An experiment is done to test what home treatment keeps trees healthier longer. One tree just gets water, so it is the _____

control

### 400

Minimum amount of data

5 changes to the IV, 3 trials per change

### 400

Experiment run without the IV, or with the IV set to some baseline value, often zero

Control

### 400

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

### 400

A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes.  Name two 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

### 400

In an experiment to determine how gas pressure is affected by temperature, the IV is_____.

Temperature

### 500

What must be done for a graph to be complete?

The axes must be labeled correctly, including units

### 500

Why does an experiment need constants?

When factors are kept constant, it ensures that the outcome is only affected by the IV, not something else.

### 500

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.

### 500

A dancer wants to see how different materials affect the amount of pressure on her feet in toe shoes.  A reasonable hypothesis is___

The more flexible the material, the less pressure she will feel on her feet

### 500

In the episode Hidden Nasties, the Mythbusters swab different surfaces to see if they are dirtier than a toilet seat. They perform each swabbing for the same amount of time.  This is an example of a(n)_____

constant
