Then, answer the question

2. Scientific Method GOAL:
I will identify the Independent (IV) and Dependent (DV) Variable in various lab investigations.
This is part of the research and preparation part of the scientific method.

3. IV vs. DV
Independent Variable: The variable that is changed by the scientist; the ‘I control’ variable
Dependent Variable: The variable that might change because of what the scientist changes – what is being measured IV
If temperature increases,
then there will be more evaporation. DV

4. At the bottom of your half sheet, write:
Dependent
Responding
Y-axis
Manipulated (changed)
Independent
X-axis DV IV X Y

5. A ball was dropped at different heights. The bounce height was measured.IV DV DV IV
Bounce Height
Different heights

6. One tank of gold fish is fed the normal amount of food once a day
One tank of gold fish is fed the normal amount of food once a day. A second tank is fed twice a day. A third tank is fed four times a day during a six week study. The fish’s weight is recorded daily. IV DV DV IV
Weight of fish
Amount of food

7. Weight of fish
Amount of food DV IV
TRUE or FALSE?
A table is used when collecting data. A graph then displays that data in an easy-to-read format. So, they should show the same information. A B
Number of Fish
Amount of Food
Number of days
Amount of Food C
Amount of Food
Weight of Fish D
Number of fish
Weight of fish

8. August 28th “Identifying Independent and Dependent Variables”
Circle and label the IV and DV in each question below. Then write the variable on its correct location on a graph. You do not need to graph any data.
On-Level: Pick and answer any 5.
Pre-AP: Pick and answer any 6. Create 1 of your own and identify the IV and DV in it.
Due tomorrow: 8/29
