What is the definition of matter?

Everything that has weight and takes up space. 
100

The state of matter that is rigid and has a fixed shape and volume. 

solid

100

This process happens when a liquid turns into a gas, like a wet shirt drying. 

evaporation

100

Cutting a piece of wood into smaller pieces is this type of change. 

physical change

100

These are materials found in our environment that are used to make other things, like wood from a tree. 

raw materials

200

Matter is made up of these tiny constantly moving particles. 

atoms

200

This state of matter has a fixed volume but takes the shape of its container. 

liquid

200

This state of matter has no fixed shape or volume and can be easily compressed. 

gas

200
This type of change results in a brand-new material being formed. 

chemical change

200

This property describes a material's ability to let water in, like a sponge or a towel. 

being absorbent

300

These are the three common states of matter found on Earth. 

solid, liquid, gas

300

In this state particles are held tightly together and only vibrate instead of moving around. 

solid

300

This is the process of a has turning back into a liquid, often seen as droplets on a cold glass. 

condensation

300

Name two of the five signs that a chemical change has occurred. 

There is a change in color, a new smell, gas bubbles, temperature change, or the formation of a new solid. 

300

This is the opposite of absorbing, it is the ability of a material, like a rain jacket or rubber boots, to keep water away. 

repelling

400

These two things are mistaken for matter, but they are actually energy. 

light (sunlight) and sound (noise) 
400

Materials like sponges have this property, while wood and stone generally do not. 

Being absorbent (or the ability to absorb) 

400

This rare process occurs when a solid turns directly into a gas without melting first. 

sublimation

400
Burning toast or a wax candle are examples of this type of change. 

chemical change

400
These are the three main types of raw materials. 

plant, animal or mined materials

500

Are the particles further apart in a solid or gas. 

gas

500

This term describes the ability of an object to float in fluid. 

buoyancy

500

Air is considered matter because it has these two properties, which can be proven by blowing up a balloon. 

It has weight (mass) and takes up space (volume). 

500

Freezing water into ice is what kind of change? 

physical change 

500

What is a raw resource that is commonly used for building? 

wood
