WS Hypotheses
Scientists pose questions after observing natural phenomena as part of the scientific method.
Develop the following questions into hypotheses and identify the each independent and dependent
variable.
* Note: Some of these questions may not convert into hypotheses with independent and
dependent variables ... Be sure to identify these questions!!!!
Example: How much water flows through a faucet?
Independent variable: Diameter of the pipe
Dependent variable: Amount of water
Hypothesis: The larger the diameter of the pipe the more water that comes out.
