These are the main methods we used to separate coffee grounds in the mini-lab.
What are decantation and filtration?
Density, Boiling Point, Color, Reactivity, pH...Hmmm how could I describe these?
What are intensive properties?
The rutherford gold-foil experiment proved that the nucleus exists when this happened to the alpha particles.

Dalton's Atomic Theory--you must give the five main principles without aide from your notes!
Use your notes (I do not want to type this all out).
