The Scientific Method

The Controlled Variables are the elements of the experiments that are constant

For distilled H₂O: Trials # 1-15 = 100.0 C; Trials #16-17 = 99.9 C; Trials 18-29 = 100.1 C; Trials # 30-40 = 100.0 C

If the results of your experiment are repeated often by other scientists they can eventually be accepted as valid.

If 2% milk is boiled, then the temp will exceed 100.0 degrees C because milk fat will raise the boiling point above H₂O.

The Dependent (Responding) Variable is the factor in the experiment we are changing and testing.

For 2% Milk: Trial #1, 3 - 12,= 100.3 C; Trials #2, 13 - 20 = 101.1 C, Trials #20 - 26 = 100.25 C; Trials # 27 - 40 = 10

The Dependent (Responding) Variable is what we measure as a result of our experiment.

In Switzerland, it is illegal to own just one guinea pig.

The oldest known guinea pig was named Snowball and lived for 14 years

7% of American adults believe chocolate milk comes from brown cows.

A Control Group gives the experimenter something to compare results to.

The Independent (Manipulated) Variable is what we measure as the Result of an Experiment.

In 40 trials, 2% milk boiled at an average of 100.2 degrees C. Our hypothesis therefore is confirmed.

Cooking and eating guinea pigs is illegal in Peru.

After publishing the results of your experiment, other scientists should try to prove you wrong.

The Independent (Manipulated) Variable is the factor in the experiment we are changing and testing.

Pternophobia is the fear of guinea pigs.

At what temperature does 2% milk come to a boil?

After publishing the results of your experiment, other scientists should accept your conclusion as fact.
