Observations
●The fish is red●The fish is made of a soft, thin
material●The fish moves when put on
hand ●The fish doesn't move the
same every time.

Hypothesis
● Hypothesis- An assumption of the outcome of an experiment following an “If_____Then____Because___” format.
● The independent variable should be in the “If” statement, and the dependent variable should follow the “Then” statement.
● Independent Variable- The variable in an experiment that is being changed.
● Dependant Variable- The variable in an experiment that is affected by the change of the Independent Variable.
● Control Group- The group in the experiment that is not changed for comparison.
● Controlled Variables- Variables that don’t change.
Hypothesis (cont.)
● Independent variable- Amount of moisture on our hands
● Dependent variable - The fish’s scale of movement from 1-10
● Control group - No moisture on our hands
● Controlled Variables - Same amount of water, same temperature, rubbed hands the same amount of time, same environment, same person each time
Hypothesis (cont.)
Hypothesis (cont.)
● If we change the level of moisture on our hands, then the fish’s level of movement will vary because the fish reacts to moisture.
Conclusion● The fish increases in movement when it comes
in contact with water● Supported our hypothesis ● Normal hand; 7 & 5 on scale of movement● Drop of water; 9 & 8 on scale of movement● Chalk; 2 & 4 on scale of movement
