3) List the FIVE traditional areas of study in chemistry. Give an EXAMPLE of what each area would
look at:
A. Organic Chemistry – Understand how plants undergo photosynthesis.
4) Give an example of PURE and APPLIED chemistry.
5) Using ONE word, describe macroscopic and microscopic. List an example of each.
6) Scientific Method – You notice that American Godzilla is smaller and weaker than Japanese

explanation for a set of observations.
Theories are subject to
