Question

physical science - graphing practice
a. graph the following information in a line graph. label and number the x and y - axis appropriately.

temperature

enzyme activity

|----|

0	0
20	10
30	15
40	20
50	8
60	5
70	0

1. what is the independent variable?
2. what is the dependent variable?
3. what is an appropriate title?

b. graph the following information in a bar graph. label and number the x and y - axis appropriately.

# of hours of study

grade

|----|

0	20
2	60
4	70
6	80
8	90
10	100

Explanation:

Step1: Identify independent variable for first - part

The variable that is being manipulated or changed is the independent variable. In the first table, temperature is being changed to observe enzyme activity.
Temperature

Step2: Identify dependent variable for first - part

The variable that depends on the independent variable is the dependent variable. Here, enzyme activity depends on temperature.
Enzyme Activity

Step3: Suggest an appropriate title for first - part

A title should describe the relationship between the two variables.
"Effect of Temperature on Enzyme Activity"

Step4: Identify independent variable for second - part

In the second table, the number of hours of study is being changed to observe the grade.

of Hours of Study

Step5: Identify dependent variable for second - part

The grade depends on the number of hours of study.
Grade

Step6: Suggest an appropriate title for second - part

A title to show the relationship between study hours and grade.
"Effect of Study Hours on Grade"

Answer:

1. Temperature
2. Enzyme Activity
3. "Effect of Temperature on Enzyme Activity"
4. # of Hours of Study
5. Grade
6. "Effect of Study Hours on Grade"
