Decode the words in the list.
After decoding them, make a
statement that will include all the
words you have revealed.

A hypothesis is a tentative
statement that proposes a possible
explanation to some phenomenon or
event. A useful hypothesis is a
testable statement which may
include a prediction.
Hypotheses:
How are
They
Written?
Hypothesis
Plant growth may be
affected by the color
of the light.
Hypothesis
Trees will change color
when it gets cold.
Hypothesis
If I play the lottery, then
I will get rich.
Hypothesis
Ultraviolet light causes
skin cancer.
Hypothesis
Temperature may cause leaves to
change color.
or
If leaf color change is related to
temperature , then exposing plants
to varied temperatures will result in
changes in leaf color.
Hypothesis
Ultra violet light may cause skin cancer.
or
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.
Hypotheses:
How are
They
Written?
And the
Answers
are….

of the light.

Hypothesis

changes in leaf color.
Hypothesis
Ultra violet light may cause skin cancer.
or
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.
Hypothesis
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.
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.
Hypothesis
Notice that
these statements
contain the
words, if and
then. They are
necessary in a
formalized
hypothesis.
If leaf color
change is
related to
temperature,
then
exposing
plants to low
temperatures
will result in
changes in
leaf color.
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.
Hypothesis
1. Rewrite the hypotheses using the
formalized.
2. Single underline the dependent variable
and double underline the independent.
3. When you are done, write one more
original hypothesis of your own using
this form.
Hypothesis
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.
Hypothesis
The ultimate value of a
formalized hypothesis is…
Hypothesis
…it forces us to think about
what results we should look
for in an experiment.
