Vocabulary
The amount of space an object or substance takes up
Volume
True or False: Carbon Dioxide (CO2) is an element.
False-- It is a molecule
What makes up all matter?
Atoms
What are two examples of detectors?
1. Smoke Detector
2. Metal Detector
When particles come closer together taking up less space
Compression
Describe what happens to air molecules when a syringe is pulled back (expanded).
Air molecules move away from each other and take up more space.
Describe why a block of gold is an element
A block of gold is made of only gold atoms.
What made the indicator paper turn to a dark color?
According to our experiment, the liquid chemical in the flask went under a phase change, and turned in to a gas. The gas filled the space of the flask, turning the indicator paper into a dark color.
A pure substance that only has one type of atom in it.
Element
Describe what happens to air molecules when the syringe is pushed in, (compressed).
The air molecules move closer together and take up less space.
What makes one element different from another element? For example, what makes silver different from gold?
They have different properties and are made of different types of atoms.
What evidence do you have that gases are different?
They give off different light using C-Spectra paper.
A small part of matter with two or more atoms combined. Can be the same or different type of atom.
Molecule
Based on your investigation (data table), can you determine what a substance is by looking at one property?
You can tell what a substance is by looking at a combination of properties like hardness and malleability.
Why is odor a property? (2 Reasons)
1. Odors smell differently
2. The same smell whether there is a little or a lot of a substance.
Is air a pure substance? Why or why not? Choose the best answer.
Air is not a pure substance. It is made of different kinds of molecules like carbon dioxide, nitrogen, oxygen and water.
The ability of an object to bend or twist
Malleability
Do elements have similar properties? What is your evidence from experiments or videos?
1. Some metals were malleable, but others were harder than another using the scratch test
Explain how Mrs. Piatek can smell her coffee.
1. The particles in my coffee mix with air and travel to my nose
2. My nose is a detector and detects the particles when they get into the air.
How were we able to identify different gases using light?
According to a video we watched, the gas gives off different colors of light because they are made up of different particles/molecules.
