100

This is anything you can change in an experiment that might affect the outcome.

What is a variable?

100
This is a mass hanging from a fixed point that is free to swing back and forth.
What is a pendulum?
100

These are four parts of the pendulum system.

What is... -penny (bob) -paper clip -string (arm) -pencil

100
Used to make a prediction of how many passengers a boat with a capacity of 65 ml would hold.
What is a two coordinate graph?
200

This is an activity or motion that repeats itself over and over.

What is a cycle?

200
This is a set of objects that is working together.
What is a system?
200

This was the only variable we tested that affected the number of swings the pendulum made in 10 seconds.

What is length of pendulum?

200
The independent variable goes on this axis when making a two-coordinate graph.
What is the x-axis (across the bottom)?
300
An investigation where you only change one variable at a time in order to see if there is an effect is called this.
What is a controlled experiment?
300
The greatest amount of fluid a container can hold is called this.
What is capacity?
300

This is the number of variables you can change at a time in a controlled experiment.

What is one?

300
The dependent variable goes on this axis when making a two-coordinate graph.
What is the y-axis (going up and down)?
400
This is the one variable you change in an experiment.
What is an independent variable?
400
This type of graph shows the outcome of a series of experiments when you change a variable by steps.
What is a two-coordinate graph?
400

This is how you can tell that something is a system. (What makes something a system?)

What is all the parts work together?

400

What relationship exists between the length of a pendulum and the number of swings it makes in 10 seconds.

The longer the string the less cycles the shorter the swing the more cycles,

500
This is the variable that you find out by doing the experiment. It is what you measure.
What is a dependent variable?
500
The basic procedure used in a controlled experiment, before changing any of the variables is called this.
What is a standard?
500

Tell four variables that might affect how many passengers a lifeboat can hold.

What is ... -passenger size -penny placement -capacity of boat (size) -boat material -water condition,

500

What is the relationship between the capacity of a lifeboat and the number of passengers it held.

The greater the capacity, the greater the passenger count.
