What is the amount of energy needed to change water in liquid form to a gas (without a temperature change)

Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.

Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each

Control Group: 20 seeds stored at room temperature

Manipulated Variable (IV): TEMPERATURE

Responding Variable (DV): GERMINATION RATE

Constants: Amount of water, same amount of time (2 weeks)

Explanation:

- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.

- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.

- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE

- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.

- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.

- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)
