Classifying Matter
Who is Empedocles?
What are "air, Earth, fire, and water"
Explain why when an ice cube freezes it floats, using the term density and the specific density of water...
When ice freezes it changes state to a solid and expands. This expansion lowers its density to less than that of water (1g/cm3) and causes it to float

Combustion (coal or gas combing with oxygen)
Electrolysis (apply electricity to water to separate the oxygen and hydrogen atoms)
Oxidation (the combination of iron with oxygen to form rust or iron oxide)
Tarnishing (Silver reacting with the sulfur in the air to form tarnsih)
