José is making toast. He puts the bread into the toaster and pushes down on the knob of the toaster. The wires in the toaster glow red, and José can feel the heat from them. With a metallic sound, the toast pops up. José uses a knife to spread jam on the toast. Name at least two things in this situation that are matter and at least two things that are not matter.

Identify each element; H, O, C,
Hydrogen, oxygen, carbon
What is the molecular make up of water.
H 2 O
What is carbon dioxide?
CO2
What is salts molecular make up?
NaCl
What are three states of matter? What two things happen to the molecules of a substance when matter changes state?
Mr. T will verify answer
Suppose that you cut a sugar cube into smaller and smaller parts. If you could separate out one molecule, which of these describes what you have?
A molecule of sugar
Which one of the container(s) contains a molecule?
Container A and B
Which container(s) contains a pure substance?
A and C
Which container(s) contains a mixture?
Container B
Which container(s) are the particles moving? Explain.
All three because all matter has moving particles.
Name a solid, liquid and gas
Ex: ice, water, water vapor
A drop of melted wax falls onto a table. It cools and becomes solid. How is it different now that it is solid?
It now has a fixed shape
Describe the movement of the particles.
The particles that make up a liquid are close together but usually farther apart than the particles in a solid are. They can slide freely past one another.
Explain what happens when you compress the gas with in this cylinder.
By compressing the gas you are increasing pressure and the temperature of the gas.
Explain why your teeth are considered to be frozen, but your mouth is not cold.
My teeth are a solid and objects that are in a solid state are considered to be frozen, they don t have to be cold to be frozen.
How do you know that a sugar molecule still exists in a glass of lemonade?
Even though you can not see it you can taste the sweet sugar molecule with your tongue.
How many atoms make up the water molecule?
Three total two Hydrogen and one Oxygen
Approximately how many atoms are in a teaspoon of water, H 2 O?
There are approximately 500,000,000,000,000,000,000,000 Atoms, pronounced five hundred sextillion.
What is the above picture showing?
That air molecules are in constant motion.
Even though each of these molecules are made up of only Oxygen atoms what makes them different?
Even though each of these are made of the Oxygen atoms the chemical bonds between each atom makes the molecule consist of unique molecular makeup.
Which container has the greatest Volume?
None they all have the same volume just different masses.
What is the above picture showing, boiling or evaporation, explain?
Evaporation, liquid water slowly changing to water vapor on the surface. NO bubbles.
Iron is an element, that means it contains
Iron only contains a single type of atom
What is the difference between a Heterogeneous Mixture and a Homogenous Mixture?
In a Heterogeneous mixture there is no set composition and you can see the individual substances. In a Homogeneous mixture there is a fixed composition and you can NOT see the individual substances.
Apply each of the following terms to the substances on the next slide as either a pure substance, heterogeneous mixture, homogeneous mixture, element.
Tap water copper Salt Sand colored water air pure substance, heterogeneous mixture, homogeneous mixture, element
