◉ Observation.
Answer: asking questions
◉ Hypothesis.
Answer: Educated guess or prediction
◉ Experimental Steps.
Answer: Methods or steps done to test the hypothesis
◉ Theory.
Answer: Explanation based inn scientific study and reasoning; if
results from repeated experiments support the hypothesis, a ______
can be developed
◉ Epidemiology.
,Answer: Observation of relationships between diet, health, and
disease patterns in different populations; focuses on patterns rather
than cause-and-effect scenarios
Example: Comparing % calories from saturated fat with coronary
heart disease incidence
◉ Observational studies.
