Anything that has mass and takes up space is known as what?

Matter

100

What is matter made up of?

Smaller particles

100

Cutting a piece of paper is an example of __________ change.

Physical

100

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

Chemical

100

The scientific study of what matter is made of and how it changes is known as what?

Chemistry

200

People can use __________ to describe and identify matter.

Properties

200

What is a characteristic of particles?

They are too small to be seen.

200

During physical change, the total __________ of matter is conserved.

Weight or mass

200

When chemical change occurs, the total weight of matter does what?

Stays the same, is conserved, or no matter is gained or lost

200

Matter is made up of particles to small to be seen. These are called what?

Atoms

300

Describe solubility.

The ability of a substance to dissolve.

300

What is an example of a particle that makes up matter?

Air, element, molecule, etc.

300

What are the three states of matter?

Solid, liquid, and gas

300

What is an example of chemical change?

Cooking or baking, rusting, burning, rotting, etc.

300

Matter made up of a single type of atom is called what?

Element

400

Name three properties of matter.

Color, hardness, reflectivity, electrical conductivity, thermal conductivity, magnetism, solubility, etc.

400

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

Model

400

In your own words, describe a physical change.

ie: A type of matter can change physically while remaining the same type of matter.

400

How do you know a chemical change has occurred?

Formation of a gas, change in color, change in odor, change in temperature, emission of light, or formation of a precipitate

400

All atoms of an element are what?

Identical or the same

500

Explain how evidence can be used to describe matter.

Observations or quantitative physical properties of matter can be used as evidence to describe types of matter.

500

What is an example of evidence that can be used to explain that matter is made up of particles too small to be seen?

Inflating a balloon, evaporating liquids, and dissolving a substance

500

How can you prove that the total weight of matter is conserved during a physical change?

Measure the matter before and after the change occurs.

500
What kind of evidence of a chemical change would you expect to find when you burn a match?

Change in temperature or emission of light

500

Describe a molecule.

Molecules form when atoms join together with other atoms.
