3. Models
In the case of atoms, scientists use large models to explain something that is very small . Atoms are so small, it would take about 1,000,000 lined up in a row to equal the thickness of a human hair.
Models of the atom were used to explain data or facts that were gathered experimentally.

Protons and neutrons are in the nucleus of the atom. Protons have a positive charge and neutrons have no charge.
Electrons travel on rings around the nucleus. They have a negative charge.

Atoms of the same element are all alike, but are different from atoms of other elements.

7. Molecule 2 or more atoms join together chemically
Molecules are groups of atoms

8. Water is a molecule. It’s chemical formula is H2O
Water is a molecule. It’s chemical formula is H2O. That means that one water molecule is made up of 2 hydrogen atoms and one oxygen atom.

Atoms are the building blocks of matter.
Cells are the building blocks of life.

11. Heat
When molecules of any kind of atoms get more energy in them than they had before, they move faster, and we call that "heat". When the molecules move faster, they hit against each other and bounce apart, and so they end up further apart from each other than they were before.
Things are hot if their molecules are moving quickly, and cold if their molecules are moving more slowly. Temperature is a way of measuring how fast the molecules are moving.

12. Melting
To melt means to change a substance from a solid to a liquid state by heating it to the melting point. Different substances melt at different temperatures. Water melts at 0°C or 32°F.

13. Rock melts at about 625 degrees Celsius
Chocolate melts at about 34 degrees Celsius

14. Freezing
To freeze means to change a substance from a liquid to a solid state by cooling it to the freezing point.

15. Boiling Point
The boiling point is the temperature at which a liquid changes to a vapor or gas. Again this is a different temperature for different substances. For water the boiling point is 100°C or 212°F.

16. What is the boiling point of rubbing alcohol?
Pour 100 mL of isopropyl alcohol (C3H8O) into a beaker.
Put in a thermometer
Heat until boiling and read the temperature
It should be about 84o

The Atoms Family was created by Kathleen Crawford, Presentation developed by Tracy Trimpe, 2006,

19. The Atoms Family Story
In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. Perky Patty Proton, like her sisters, is quite large with a huge smile and eyes that sparkle (+). Patty is always happy and has a very positive personality. Nerdy Nelda Neutron is large like Patty, but she has a boring, flat mouth and eyes with zero expression (o). Her family is very apathetic and neutral about everything. Patty, Nelda, and their sisters spend all their time at the arcade.

20. Around the Nucleus Arcade, you will find a series of roadways that are used by another member of the Atoms Family, Enraged Elliott Electron. Elliott races madly around the Arcade on his bright red chrome-plated Harley-Davidson. He rides so fast that no one can be sure where he is at any time. Elliott is much smaller than Patty and Nelda and he is always angry because these bigger relatives will not let him in the Arcade. He has a frown on his face, eyes that are squinted with anger, and a very negative (-) attitude.

21. The first energy street can only hold only two Electron brothers
The first energy street can only hold only two Electron brothers. The second energy street, called the Energy Freeway, can hold 8 brothers. The third energy street, called the Energy Superhighway, can hold 18 of the brothers.
Matterville
Energy Superhighway Can hold 18 electrons
Energy Freeway Can hold 8 electrons
Nucleus Arcade Contains protons & neutrons
Energy Street Can hold 2 electrons

22. The morale of Matterville is stable as long as each negative Electron brother is balanced out by one positive Proton sister. The number of residents in Matterville depends on the Proton and Neutron families.
Challenge: What would happen to the morale of Matterville if one Elliott Electron was kidnapped?

23. Challenge 2: What would happen to the morale of Matterville if one Elliott Electron moved to Matterville?
