Examine the properties of materials.

Examine the way things react.



1 mole of a gas is about 22 liters

Combining oxygen and hydrogen we have about 50 liters of material

OVER SIMPLIFYING = 1 mole of water

1 mole of water = 18 grams

Water has a density of 1 gm per cubic cm

1 liter is 1000 cc



These properties and reactions are grealy simplified when we understand.



QUANTUM STRUCTURE (non intuitive, at least at first)



Activity 1 charges, electric force and building atoms


Make each student a particle and build atoms while discussing location, structure, impact of forces, neutrality.


Make a person a single atom and (+ charge is body charge is exended) move through space
