What is a fair test?
Where we test variables that are fair.
An investigation where only one thing changes.
An experiment where we see what is happening.
An investigation that involves materials
What is an independent variable (I.V.) of an investigation?
What we are testing.
The things we are measuring.
The one thing that is changing in the investigation.
The things that are staying the same.
What is a CONTROL variable of an investigation?
What we are testing.
The things we are measuring.

The thing(s) that are staying the same.
In an experiment, one chicken is injected with growth hormone while another chicken is not injected.
This continues for one year.
After one year the chickens are weighed.
Choose the correct combination.
(Hint:
INDEPENDENT VARIABLE IS WHAT YOU CHANGE
DEPENDENT VARIABLE IS WHAT YOU MEASURE
independent = growth hormone; dependent = weight of chicken
independent = weight of chicken; dependent = growth hormone

The other arm is not sprayed.
The number of bites on each arm is recorded after 2 hours.
Choose the correct combination.
(Hint:
INDEPENDENT VARIABLE IS WHAT YOU CHANGE
DEPENDENT VARIABLE IS WHAT YOU MEASURE
independent = mosquito bites; dependent = mosquito repellent
independent = mosquito repellent; dependent = mosquito bites
Group A exercises every day for one month.
Group B does NO exercise for one month.
Everyone's weight is measured at the end of the month.

(Hint:
INDEPENDENT VARIABLE IS WHAT YOU CHANGE
DEPENDENT VARIABLE IS WHAT YOU MEASURE
independent = exercise; dependent = weight of people
independent = weight of people; dependent = exercise
Class A reviews for the Science exam.
Class B does not.
Their results are recorded the next day.
Choose the correct combination.
(Hint:
INDEPENDENT VARIABLE IS WHAT YOU CHANGE
DEPENDENT VARIABLE IS WHAT YOU MEASURE
independent = exam results; dependent = studying
independent = studying; dependent = exam results

What makes an experiment fair?
It is fun and exciting
It proves your prediction correct
Only one variable is changed at a time and a control is present
Many variables are changed and only one factor is kept constant.
In a fair test, how will you decide which factor should be the variable?
It depends on what we are trying to find out.
It depends on the constant factors.
Any factor can be the variable.
None of the above.
