Step 1: Make observationsStep 2: Ask a questionStep 3: Make a hypothesisStep 4: Set up an experimentStep 5: Analyze the dataStep 6: Repeat experimentStep 7: Draw conclusion
THE PROCESS

constants
all factors which are NOT allowed to change during the
experiment

A variable is something that changes.
There are 2 types of variables:
Independent variableDependent variable

independent independent variablevariable
the variable that is changed on purpose by the
experimenteraka cause, stimulus, reason, manipulated variable, etc.
This is the ‘’if” part of a hypothesis.

repeated trials
the number of times the experiment is repeated
The more times you repeat the The more times you repeat the experiment, the more VALID your experiment, the more VALID your
results are.results are.

Hypotheses are tentative and testable statements Hypotheses are supported or not supported by observational evidencetheories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers
THEORIES VS. HYPOTHESES
