Matter
Define Explain
To describe how something works or why something happens.
What is a Substance?
A group of the same Molecules joined together.

B: 5 trillion trillion water molecules
What is a Molecule made of?
Atoms
Define Property
What you can observe or measure about something that helps you identify or describe it.
What is a Mixture?
More than one substance combined.
What model did we use that demonstrated how different molecules have different sizes and shapes using food.
The Pasta model
What are called the building blocks of matter?
atoms
What is a an Atom?
The smallest unit of matter that can be measured.
Define Observation
To use any of the 5 senses to get her information about something.
Will a substance have the same properties as the molecules that make it?
Yes, because the properties of molecules will be the same as the substance since the substance is just made of those molecules.
What model demonstrated how different molecules had different properties by seeing which ones would be blown away by wind?
The Fan Model
When molecules hold together that means they are ____ each other.
attracted to
Order from smallest to largest.
Substance, Mixture, Atoms, Molecules
Atoms
Molecules
Substance
Mixture
Define Inference
Something you figure out based on observations and what you already know
They separated blood with a "Centrifuge test". Using this test the blood separated into solid parts and liquid plasma. How did the test separate the mixtures?
They spun the test tubes at a very fast speed. until the solids and liquids were separated.
What model did we use to see the dyes separate on a piece of special paper?
Chromatography model
In which state of matter will you find particles that are free to move around, bounce all over, and are the farthest distance away from each other?
gas
What is it called when Molecules and Atoms move without being touched?
Attraction
Define Attraction
To pull on an object without touching it.
How did they separate the gasses in the book modeling matter?
Shot the gasses through a looping tube and the lightest ones came out first because they traveled the fastest.
What model did we draw how the dye molecules separated on chromatography paper?
Nano vision chromatography model
What happens to the particles in matter when they warm up?
the particles speed up
