A direct relationship looks like this.
What is an increasing (upward slope) line?
100
This type of physics deals with motion
What is mechanics?
200
This group is normal or untreated - used for comparison
What is the control group?

A coach has his players record all the food they ate then compares the amount of carbs in their diet to their 200m run times. What is the independent variable?
What is the amount of carbs in their diet?
200
For data with categories, you should do this type of graph
What is a bar graph?
200
An inverse relationship looks like this
What is a decreasing (downward slope) line
200
This type of physics deals with sound and earthquakes
What is vibrations and waves?
300
This part of the experiment is controlled or chosen by the experimenter.
What is the independent variable?
300
A farmer applies chemical pesticide to one field, ladybugs (which eat other bugs) to another field, and no pesticide to a third field. Then he measures the amount of holes in his leaves. This is the independent variable in this experiment.
What is chemical pesticide vs ladybugs vs no pesticide?
300
When should you use a line graph?
When both of the variables are numbers
300
This variable is the cause in an experiment
What is the independent variable?
300
This type of physics deals with light
What is optics?
400
This group receives a special treatment or is different from the norm.
What is the experimental group?
400
A person uses Olive hair relaxer and Just For Me hair relaxer then records how long until their curls come back. What is the dependent variable?
What is the time until the curls come back
400
On a table, where does the independent variable go?
What is the left side?
400
This variable is the effect in an experiment
What is the dependent variable?
400
This type of physics deals with electricity
What is electromagnetism?
500
This part of the experiment is measured during the experiment.
What is the dependent variable?
500
You tell two groups of people that they received a certain grade on a test (either a 62% or a 95% regardless of their real score) then you have them deliver a speech and measure how many times they say "um" or "uh". This is the independent variable.
What is the fake test score they received
500
On a graph, where does the dependent variable go?
What is the y axis (side) (vertical)
500
The conclusion for this graph is this.
What is :speed is directly related to time?
