We are learning to understand that all matter is made up of small particles called atoms. (PS-6-1)
We are looking for a group of substances made up of only one kind of atom: ELEMENT
We are looking for two or more atoms that are joined together chemically: MOLECULE
We are looking for two or more different elements that are joined together chemically: COMPOUND
 We are looking for compounds to have properties that are different from the properties of the elements that form
them.
ESSENTIAL VOCABULARY:
Atom – smallest part of an element, too tiny to see
Element – pure substance that cannot be broken down – 118 on Periodic Table
Molecule – smallest part of a compound, 2 or more atoms combined, too tiny to see
Compound – 2 or more elements chemically combined

Animal Names
Organized in rows and columns based on the properties
they have in common
Songs about the
Periodic Table
Example of groups are: metals vs nonmetals
Examples of groups are: solids vs gases
Each element has a symbol (one or two letters)
Some symbols are based on the Latin name (Plumbum = Lead)

We are learning to understand that changes of state can be explained by a model of matter composed of atoms and/or molecules that
are in motion. (PS-6-2)
We are looking for the mass and weight of a substance, in a closed system, to be conserved (stay the same) when it has a change
of state.
ESSENTIAL VOCABULARY:
Open System – the mass would change, since it is able to escape
Closed System - the mass would stay the same, since it is closed with a lid, cap or balloon

Burning Sugar
Plop Plop Fizz Fizz
WE HAVE CONCLUDED THAT…
When a chemical reaction occurs in a closed system,
matter is not lost or gained.
When a chemical reaction occurs in an open system,
matter is able to escape into the air.
In the burning sugar lab, CO2 escaped
and the mass went down.
In the Plop Plop Fizz Fizz lab, the balloon acted as a lid
and the mass stayed the same.

We are looking for molecules to change structure, often through collision, which creates a new
substance (a chemical change).
