Responses to fire may vary
depending on how the student thinks of fire.
Fire may be considered matter or energy—the
vaporized gases in the flame are matter but the
light and heat emitted are energy. All matter is
made up of particles (e.g., atoms or molecules);
has weight and mass; takes up space (has vol-
ume); and exists in the forms of solid, liquid,
gas, or plasma. In order to be considered mat-
ter, an object, material, or substance must meet
these characteristics.

3. Items on the list considered to be matter are: rocks, baby powder, milk, air, dust, cells, atoms, smoke, salt, Mars, Jupiter, steam, rotten apples, water, bacteria, oxygen, stars, and dissolved sugar.
What about fire?
Responses to fire may vary depending on how the student thinks of fire.
Fire may be considered matter or energy—the vaporized gases in the flame are matter but the light and heat emitted are energy.

4. is made up of particles (e.g., atoms or molecules);
All Matter:
is made up of particles (e.g., atoms or molecules);
has weight and mass;
takes up space (has volume);
exists in the forms of solid, liquid, gas, or plasma.

5. What makes up the larger picture?
What makes up the larger picture?
What do the smaller pictures have in common?
How is this an example of the relationship between matter and elements?
Pick a smaller picture, describe it.
What might make up an element?

6. Matter is composed of extremely small particles called atoms.
These particles are too small to be seen with a microscope.
Atoms have all the properties of matter: mass and volume
mass: How much stuff is in something
volume: How much space something takes up

7. • a human hair is about 1 million carbon atoms wide.
How small are atoms?
Atoms are so small that...
• if you could enlarge a penny until it was as wide as the US, each of its atoms
would be only about 3 cm in diameter – about the size of a ping-pong ball
• a human hair is about 1 million carbon atoms wide.
• a typical human cell contains roughly 1 trillion atoms.
• a speck of dust might contain 3x10^12 (3 trillion) atoms.

8. element - a basic substance that can't be simplified (hydrogen, oxygen, gold, etc...)
atom - the smallest amount of an element
A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds. (ex: C6H12O6 - Sugar)

9. All atoms of the same element have the same properties (qualities or characteristics).
Iron atoms have the same mass and occupy the same amount of space, so all matter made of iron has the same properties because of the iron atoms

10. Matter is made of elements.
There are more than 100 elements that combine to make up all living and nonliving things.
Elements are shown on a Periodic Table.

11. drive home the point that all matter is made up of some combination of these elements.

12. Matter and Elements Examples

13. Water is matter. It is made of the elements hydrogen and oxygen.

14. A diamond is matter. One element makes it up – carbon.

15. Another example of matter is sugar (glucose)
Another example of matter is sugar (glucose). It is composed of the elements carbon, hydrogen and oxygen.

16. Zinc oxide is matter. The elements that are in it are zinc and oxygen.

17. A pencil lead is matter. It is also made of the element carbon.

28. Carbon=found in charcoal Oxygen/hydrogen=colorless gases
When elements are combined to make a compound, the new substance has properties different from those of the original elements.
Example: table sugar is made up of 3 elements- Carbon, Oxygen and Hydrogen.
Carbon=found in charcoal
Oxygen/hydrogen=colorless gases
Do sugar crystals resemble them?

29. Most matter occurs in mixtures.
A mixture is made from two or more substances (elements or compounds) that are in the same place but are NOT chemically combined.

30. Mixtures differ from compounds in 2 ways:
The substances in a mixture keep their individual properties.
The parts of a mixture are not necessarily present in set ratios.
Example: soil has particles of sand, tiny bits of clay, and pieces of decaying plants.
If you were to grab 2 handfuls of soil would they be made up of the same amount of clay, sand, and decaying plant matter?

31. Mixture, Element, or Compound?
Iron
Chex Mix
Air
Salt
Water
Gold
Sugar
How are atoms and molecules related?

32. get out the notes from yesterday -the half sheet and the notebook paper Review what a mixture is with your neighbor And how it is different from a compound. What do mixtures look like?

33. Reminder: Mixtures Mixtures are not chemically combined
Can be separated by physical means (dissolution, centrifuge, gravimetric filtering, etc.).

34. Indicators of Homogenous Mixtures
Have the same composition throughout (look the same)
Components are indistinguishable
Examples: milk, yogurt, etc.
Brainstorm more examples of homogenous mixtures.

35. What are solutions? Solutions are homogenous mixtures
created when something is completely dissolved in water
they are easily separated by distillation or evaporation
Examples: sugar water, salt water

36. Indicators of Heterogenous Mixtures
Do not have same composition throughout
Components are distinguishable
Examples: fruit salad, vegetable soup, etc.
Brainstorm more examples of heterogenous mixtures.

37. What are colloids?
Colloids are solutions. They can be described as a substance trapped inside another substance.
For example: air trapped inside the fat molecules in whipped cream.
Brainstorm more ideas of colloids: fog, egg merangue, jello, smoke, etc.
