1. What’s the Matter? Matter “Stuff” that Everything Made of is made of!
Atoms
Matter
Has Volume=
Takes Up
Space
Has Mass=
The Amount
of Matter
in an Object

2. Don’t Sweat the Small Stuff!

3. What is the “Small Stuff” anyway?
Atoms
Elements
Molecules
Compounds

4. Atoms Basic unit of matter
The smallest particle of a substance that has all of the properties of that substance.
Example= the element Gold is made of gold atoms

5. Elements A pure substance made of only one kind of atom.
Examples= Gold, Hydrogen, Carbon, etc.
Elements are found on the Periodic Table of Elements.
Here is a song about them…

6. Molecules Made up of two or more atoms joined tightly together.
Small particle of the entire substance or compound
Atoms in a molecule may be of the same element or of different elements.
Examples= 1 molecule of the element oxygen or 1 molecule of water H2O

7. Compounds
A substance whose molecules contain atoms of different elements combined chemically.
Most matter exists as compounds.
Examples= Water, Carbon Dioxide, etc.

8. What is the difference between a Compound and a Molecule?
A molecule is formed when two or more atoms join together chemically.
A compound is a molecule that contains at least two different elements.

9. Compound vs. Molecule
All compounds are molecules but not all molecules are compounds!
Compound = entire substance
Molecule = small particle of entire substance

10. Smallest part of a substance
Atom
Smallest part of a substance
Has all of the properties of that substance
Compound
Molecules
containing
atoms
of different
elements
Element
Pure Substance
Made of 1 kind
of atom
Molecule
2 or more atoms
joined tightly
together
Smallest part
of compound

11. Atom
Smallest part of a substance
Has all of the properties of that substance

12. Element
Pure Substance
Made of 1 kind of atom

13. Molecule
2 or more atoms
joined tightly
together
Smallest part
of compound

14. Compound
Molecules containing atoms of different elements

15. Size of Atoms Tiny! Tinier than the cells and germs.
Too small to be seen with ordinary microscopes
Atoms are so small that it would take 100 million atoms placed side by side to form a row only 1 cm long which is about the width of your pinky finger!
