experimentation
3. What is a hypothesis: A tentative explanation of observations
(Must be able to be tested)
4. What do the laws of science summarize?: A vast number of

,6. T/F A theory does not turn into a law: T
some processes are too old or impossible to be 100% on so 99.999 is
closest.

2. Microscopic domain
3. Symbolic domain
8. Define Macroscopic domain: realm of everyday things that are
large enough to sense directly by human sight and touch
9. Define Microscopic Domain: realm of things that are much too
small to be sensed directly
Almost always visited in the imagination (someone coughing on
doorknob)
10. Define symbolic domain: the specialized language used to
represent components of the macroscopic and microscopic
domains, such as chemical symbols.
