Slide 1 - Diapositive
Slide 2 - Diapositive
Introduction
Experimental variables are important factors that can influence the outcome of an experiment. Let's explore the different types of variables.
Slide 3 - Diapositive
What do you already know about experimental variables?
Slide 4 - Carte mentale
Independent Variable
The independent variable is the factor that the researcher intentionally changes or manipulates in an experiment.
Slide 5 - Diapositive
Dependent Variable
The dependent variable is the factor that is being measured or observed. It is the outcome or result of the experiment.
Slide 6 - Diapositive
Control Variable
The control variable is the factor that remains constant or unchanged throughout the experiment. It helps establish a baseline for comparison.
Slide 7 - Diapositive
Identifying Variables
In an experiment, it's important to identify the independent, dependent, and control variables. Let's practice identifying variables.
Slide 8 - Diapositive
What is the purpose of identifying variables in an experiment?
A
To make the experiment more complex.
B
To understand the cause and effect relationship and ensure reliable results.
C
To confuse the participants.
D
To waste time and resources.
Slide 9 - Quiz
Which variable is not important in an experiment?
A
The control variable.
B
The dependent variable.
C
None of the variables are unimportant.
D
The independent variable.
Slide 10 - Quiz
What is the control variable in an experiment?
A
The variable that is measured or observed.
B
The variable that is not important.
C
The variable that stays the same.
D
The variable that is purposely changed or manipulated.
Slide 11 - Quiz
What is the dependent variable in an experiment?
A
The variable that is not important.
B
The variable that stays the same.
C
The variable that is measured or observed.
D
The variable that is purposely changed or manipulated.
Slide 12 - Quiz
What is the independent variable in an experiment?
A
The variable that is measured or observed.
B
The variable that is purposely changed or manipulated.
C
The variable that stays the same.
D
The variable that is not important.

How can the overall energy change of a reaction be determined from a reaction profile?
A
By calculating the difference in energy between the reactants and products
B
By measuring the temperature of the reaction
C
By balancing the chemical equation
D
By counting the number of reactant molecules
Slide 28 - Quiz
Where on a reaction profile is the activation energy located?
A
At the starting point (beginning)
B
At the ending point (completion)
C
At the lowest point (valley)
D
At the highest point (peak)
