changes in leaf color.

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.
If leaf color change is related to temperature, then exposing plants to
low temperatures will result in changes in leaf color.
Hypothesis
![Page 24: Hypotheses: How are They Written? Plant growth may be affected by the color of the light. Hypothesis](https://reader036.vdocuments.us/reader036/viewer/2022062713/56649f575503460f94c7bedb/html5/thumbnails/24.jpg)
Notice that these statements contain the words, if and then. They are necessary in a formalized hypothesis.
Ifskin cancer is
related to ultraviolet light,
then people with a
high exposure to UV light will have
a higher frequency of skin
cancer.
Hypothesis
![Page 25: Hypotheses: How are They Written? Plant growth may be affected by the color of the light. Hypothesis](https://reader036.vdocuments.us/reader036/viewer/2022062713/56649f575503460f94c7bedb/html5/thumbnails/25.jpg)
Formalized hypotheses contain two variables. One is "independent" and the other is "dependent." The independent variable is the one you, the "scientist" control and the dependent variable is the one that you observe and/or measure the results.
If leaf color change is related to
temperature, then exposing
plants to low temperatures
will result in changes in leaf color.

Rewrite the hypotheses using the formalized. Single underline the dependent
variable and double underline the independent. When you are done, write
one more original hypothesis of your own using this form.

1. Salt in soil may affect plant growth.
2. Plant growth may be affected by the color of the light.
3. Bacterial growth may be affected by temperature.

The ultimate value of a formalized hypothesis is…

…it forces us to think about what results we should look
for in an experiment.
