GORP
100
Anything that takes up space and has mass
What is matter?
100
Saltwater, GORP, air, or a Dairy Queen blizzard.
What are mixtures? (some of these are homogeneous and some are heterogenous)
100
The smallest particle of matter that maintains its properties
What is an atom?
100
A combination of two or more substances whose abundance varies throughout.
What is a heterogeneous mixture?
100
The smallest unit of a compound
What is a molecule?
200

What is mass?
200
The temperature at which a liquid changes to a solid
What is: freezing point?
200
The dense, central core of an atom containing the heaviest particles of the atom
What is a nucleus?
200
A mixture in which one substance dissolves in another

This happens to molecules when the temperature increases.
What is: the molecules speed up?
300
The part of the atom whose mass is almost equal to that of a proton.
What is a neutron? (remember, electrons are much, much smaller)
300
Elements and Compounds are both classified as these.
