1
In the experiment to answer: Does the battery brand affect the running time of a toy car? The independent variable is
Temperature of battery
Running time of toy car
Brand of battery
Brand of toy car
2
In the investigation: Does the water temperature change as you dive deeper in an ocean? The dependent variable is
The brand of thermometer used to measure the temperature
The different ocean depths that water temperature is measured
The temperature data collected
The time of day that the experiment is conducted
3
The variable that is changed or manipulated by the scientist in an experiment
Dependent Variable
Responding Variable
Constant Variable
Independent Variable
4
The experiment to answer: Does the length of study time affect test scores? The length of study time is the
constant factor
responding variable
independent variable
dependent variable
5
In the experiment to answer: Does the battery brand affect the running time of a toy car? A constant could be
Running time of toy car
Brand of battery
Temperature of battery
Brand of toy car
6
Factors that can change in an experiment
Hypothesis
Variables
Constants
Conclusion
7
What is NOT TRUE about a hypothesis?
It is an educated prediction of what will happen in the experiment
It is based on research
It is always proven correct.
It is addresses the scientific question being investigated.

10
In an experiment, when the independent variable is manipulated, it causes a change in the
constant variable
independent variable
manipulated variable
dependent variable
11
Giving 3 types of trees different amounts of fertilizer and water to see which grows fastest. What statement is true?
This experiment kept all factors constant
This experiment changed too many variables
This is a valid experiment
This experiment changed only one variable
12
In making a bar graph on which fertilizer helped trees produce more fruits, the number of fruits will be plotted on the
z-axis
x-axis
y-axis
a-axis
13
This is critical to ensure that your conclusions are valid.
Ensure that your results are repeatable
Only do the experiment once, if you already got the results you want.
Change as many variables as you need
Discard data that did not fit your hypothesis
14
Also called the responding variable, as this factor responds to the change in the manipulated variable.
Independent Variable
Constant Variable
Manipulated Variable
Dependent Variable

z-axis
a-axis
y-axis
x-axis
16
In the experiment: Does the brand of fertilizer affect how much fruit a tree produces? The responding variable is
Amount of fertilizer
Number of fruits produced
Type of fruit tree
Brand of fertilizer
17
In the experiment: Does chewing gum help students focus and answer math problems faster? The manipulated variable is
Age of students
Time it took for students to solve math problems
Student math test score.
Whether students chew gum or not chew gum
18
An experiment in which only one variable is manipulated at a time
Scientific Guess
Controlled Experiment
Scientific Theory
Random Experiment
19
When graphing the data in a controlled experiment, the independent variable is usually plotted along the
a-axis
z-axis
x-axis
