Activating Strategy
Let’s See What you Know…
In our previous lesson we learned that the pencil is
made of ______?If you look closely at the tip of a sharpened pencil, you will see that it is made of a
specific type of matter called graphite.
The image shows a close up picture of the graphite. The graphite is made up of even
smaller particles called _____.
These particles contain even smaller particles
called _____________________
atoms
protons, neutrons, electrons
matter

A Chemical Formula is a representation of a substance using symbols for its essential
elements.

A Chemical Formula represents in symbols and numbers the amount of atoms in a specific type of
matter.
Look at Part III of your Atoms and Molecules Notes Sheet. Let’s examine a few Chemical
Formulas.
H2O = Water
How many atoms are there in H2O?There are 2 Hydrogen Atoms and 1 Oxygen Atom

Review: What is the Law of Conservation of
Matter?The Law of Conservation of
Matter [Mass] states that matter cannot be created or destroyed.
It changes form.A Chemical Equation can
illustrate the Law of Conservation of Matter.
