1. Hypothesis a testable educated guess
2. Experiment how we test hypotheses
3. Variable Idea to be tested (only one)
4. Control Something the variable is
tested against
5. Experimental protocol How do you do the test?
6. Results Data generated comparing
variable to controls. Includes
statistics to show results are
meaningful
7. Conclusion Interpretation of results
8. independent variable The experimental factor that
is manipulated; the variable
whose effect is being studied.
9. dependent variable The variable that depends on
the independent variable
10. Protons Positively charged particles
11. Neutrons the particles of the nucleus
that have no charge
12. Electrons Negatively charged particles
13. Isotopes same atomic #
different mass #
14. Ions The number of electrons is ei-
ther greater than, or less than,
the number of protons
15. atomic mass
