arise from infection
Robert Koch - Established Koch's postulates, a series of proofs that verified the
germ theory of disease, linked a specific microorganism with a specific disease
(Anthrax- Bacillus anthracis). Also developed numerous lab techniques

3. Experiment - Test the question with an experiment
4. Observe outcome - Observe what is seen from the experiment
5. Analyze data and draw conclusions - Explain what was seen and whether or not
the hypothesis was corrrect
