The universe is made of MATTER and ENERGY. Everything can be classified under matter or
energy.
MATTER is a a SUBSTANCE
with
MASS (has grams) and VOLUME (volumes take up space)
ENERGY can make matter
move. Forms of energy include
KINETIC ENERGY - MOVEMENT
LIGHT ENERGY – photons moving
SOUND E… -
vibrations. Matter moving in a wave.
ELECTRICAL ENERGY – Flow of
electrons
MAGNETIC
IN QUANTITATIVE science, we define things that are measurable. Some things are not measurable
QUALITATIVE science (behavioural science) is difficult to measure but
must be described and characterized in non measurable terms.
MATTER
Is made of subunits called ATOMS.
An atom is the basic unit of
all matter in our universe. Everything
is made of ATOMS. THERE IS NOTHING THAT
IS NOT MADE OF ATOMS.
ANALOGY – USING A STORY TO
HELP UNDERSTAND A CONCEPT
AN ANALOGY OF ATOMS AND MATTER
ATOMS are like lego
-Lego comes in many different shapes and sizes. So do atoms.
- you can use lego to build things and break them apart and re-use the
lego to build different things.
If I have three tubs of lego and
we have three different types of lego, and
each tub has the same type…
ELEMENT – A GROUPING (or a box) of the same type of atom
COMPOUND– when you attach two or more different types of atoms together
MOLECULE – two or more of the same
type of atom attached together.
How IONIC COMPOUNDS form
Atoms of an element can have a tendency to form one of two charges.
Some atoms can form a positive charge
+ they are called
CATIONS
Some atoms can form a negative charge
-
ANIONS
Opposite charges always attract thus CATIONS ALWAYS JOIN ANIONS
Use lego pieces and build the following compounds
