The variable that the scientist changes is called:
Independent Variable
100
To know the velocity of an object you must know the direction and ______________.
Speed
100
If speed is measured in kilometers per hour and time is measured in hours, the unit of acceleration is
kilometers per hour per hour
or
(km/hr)/hr
or
km/hr*hr
or
km/hr^2
100
In a graph of distance vs. time, what does the slope represent?
Speed
200
The metric system is based on the number:
10
200
The variable that the scientist measures is called:
Dependent Variable
200
If you know the distance an object has travelled in a certain amount of time you can find the _____________ of the object.
Speed.
200
Acceleration is a change in _________ and ___________.
Velocity (speed) and Direction
200
What conclusion can you make for the data shown on this graph?
As temperature increases the ice cube melts in a shorter amount of time.
300
The amount of space an object takes up is called:
Volume
300
What is the Independent Variable and on which axis is it graphed?
Temperature (*C), X-Axis
300
What is the equation for Speed?
Distance divided by Time
300
What color is Mrs. Reed's car?

What is the Dependent Variable and on which axis is it graphed?
Time (seconds), Y-Axis
400
If you are travelling 60 kilometers in 3 hours, what is your average speed?
20 km/hr
400
What is the equation for acceleration?
(Final Speed - Initial Speed) / Time
or
(Final Speed - Initial Speed) divided by Time
400
To show a linear trend on a scatter plot you could draw a ___________________.
Line of Best Fit
500
The measure of the force of gravity on you is called:
Weight

Create a data table that shows 5 trials of 3 variations of this question's Independent Variable.
Question: In what color of light will plants grow faster?
Color 1 - Color 2 - Color 3
Plant A
Plant B
Plant C
Plant D
Plant E
500
At what time is the speed constant?
From 3-5 seconds
500
At what time does the ball accelerate?
From 0 to 3 seconds.
500
At what time does the ball decelerate (slow down)?
The ball does not decelerate according to this graph. Deceleration would look like a downward slope on this graph.
