Anything that has mass and takes up space

What is matter?

100

Matter is made up of this

What are smaller particles?

100

Cutting a piece of paper is an example of a __________change.

What is physial?

100

When two or more different substances are mixed, a new substance may be formed. This is called a _________change.

What is chemical?

100

The scientific study of what matter is made of andhow it changes

What is chemistry?
200

People can use this to describe and identify matter

What are properties?

200

Name a characteristic of particles

What is they are too small to be seen?

200

During a physical change, the total _________of matter is conserved.

What is weight or mass?

200

When a chemical change occurs, the total weight of matter does this

What is stays the same/ is conserved/ no matter is gained or lost? (any of these three)

200

Matter is made up of particles too small to be seen

What are atoms?

300

Describe solubility

What is the ability of a substance to dissolve?

300

Give an example of a particle that makes up matter

What is air? (this is just one example)

300
Name the three states of matter.

What are solid, liquid, gas?

300

Give an example of a chemical change

Answer may be cooking/baking, rusting, burning a paper, rotting good, etc

300

Matter made up of a single type of atom

What is an element?
400

Name three properties of matter

Acceptable answers: color, hardness, reflectivity, electrical conductivity, thermal conductivity, magnetism, solubility

400

Blowing up a balloon can be used as a _________to show that particles exist.

What is a model?

400

Describe a physical change in your own words.

Acceptable answer: What is a type of matter that changes physically while remaining the same type of matter?
400
How do you know when a chemical change has occurred?
Acceptable answers: formation of gas, change in color, change in odor, change in temperature, emission of light, formation of a precipitate
400

All of the atoms of an element are _____

What is identical?

500

Explain how evidence can be used to describe matter

Observations or quantative measurements of physical properties of matter can be used as evidence to describe types of matter

500
Name an example of evidence that can be used to explain that matter is made of particles too small to be seen

Acceptable answers: Inflating a balloon, evaporating liquids, dissolving a substance

500

Describe how you can prove that the total weight of matter is conserved during a physical change

What is you can measure the matter before and after the change occurs?

500

Give evidence of a chemical change that you would expect to find when  you burn a match

What is change in temperature or emission of light?

500

Describe a molecule.

What is when atoms join together with other atoms?
