1. Students read introduction
to the history of the idea of the atom.
a.
A brief connection to the concept of "why is it all here?"
b.
Connect to "self knowledge" as knowledge of your world.
4. Introduce basic reading
rules of periodic table. Including a brief history of the table.
5. Ask students to consider
and name the similar qualities of a candle flame, ice cube and wood.
6. Ask students to help
us discover and invent the reasoning for trying to find and define the
existence of the atom.
7. The concept of periodic
cycle will be reviewed and enhanced.
