Getting Started: List 2 things that scientists could do to learn more about a disease and its cause or causes?

Challenge: What are the common elements of all scientific problem-solving methods?

Key Words: ethics, evidence, inference, observation

Results: See Worksheets Fill in “Notes on the Pellagra Story” sheet Complete “Observation and Inference” sheet Compare “Dr. Goldberger and the Traditional Scientific Method’

Analysis: Answer Analysis Questions 1a, 1b, 2a, (homework)

Hypothesis: An educated guess

Scientific Method: Steps that scientists use to complete their work.

Ethics: Looking at what is right and wrong

Evidence: Info that is collected to see if something is true.

Inference: A conclusion based on evidence

Observation: Looking at something carefully.

Key Words:

Should a prisoner who participated in Dr. Goldberger’s experiment on Pallegra be allowed to be released

from prison?
