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

Ratio

 

These properties and reactions are grealy simplified when we understand.

ELECTRIC FORCE

ATOMIC NATURE

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
