Independent versus Dependent Variable Worksheet.
An
independent variable
is the one thing you intend to vary in an experiment.
A
dependent variable
is the thing that will change that you intend to measure as a quantitative assessment
of the effect.
In the following examples identify the independent and dependent variables and then also list several
potential confounding variables that the experimenters would have to consider.
Sample Hypotheses
1. If
skin cancer is related to ultraviolet light,
then
people with a high exposure to UV light will have a
higher frequency of skin cancer. What will you do to test this proposal? What will you vary or change?
What will you measure?

2. If
leaf color change is related to temperature,
then
exposing plants to low temperatures will result in
changes in leaf color.

3. If
the speed of plant germination is related to the hardness of the hull of its seed,
then
softening the seed
with water or a weakly acidic solution prior to planting will hasten germination. Blah, Blah, Blah…

4. If
photosynthesis is related to light energy,
then
the portions of a leaf shaded from light will test negative
for starch, since starch is a product of photosynthesis.

5. If
animal metabolism is related to temperature,
then
increasing resting room temperature will increase
animal metabolism (as measured by carbon dioxide gas production which is one of the waste products of
animal metabolism).

6. If
root growth is related to gravity,
then
roots will always turn toward the earth regardless of a seed's
orientation.

7. If
hatching of brine shrimp is related to salinity (or temperature),
then
the greater the salt concentration,
the higher the hatching rate.

9. If
the thickness of annual growth rings in trees is related to annual rainfall,
then
examining wood
samples will reveal correlations in the growth rings to the historical records for rainfall in its environment.
