2. Structure of Matter
Study Pack #9

3. To be or not to be… What is matter? What is not matter?
Matter is anything that has mass and takes up space

4. To be or not to be… Is it matter? Air Light Heat Water A rainbow

5. What is matter made of?
Atoms are the smallest particles that make up matter
Atoms are so small that it would take 1 million of them lined up in a row to equal the thickness of a human hair

6. Inside of an Atom Atoms are made up of 3 types of particles called:
Protons
Neutrons
Electrons

7. Inside of an Atom In the center is the nucleus
The nucleus is made of protons and neutrons
Outside the nucleus there are electrons

8. Inside of an Atom Electrical Charge Protons are positive
Electrons are negative
Neutrons are neutral

9. Law of Conservation of Mass
Says that we cannot create or destroy matter!
This is because we cannot create or destroy the atoms that make up matter!

10. What did you learn? True or False
Matter is anything that has mass and takes up space.
Matter can be destroyed.
Matter is made up of small particles.
Protons and electrons are found in the nucleus.
Protons have a positive electrical charge.

11. Today’s Target
I understand that matter is composed of parts too small to be seen without magnification.
