What's the "Matter?"
The Heat is On!
Crazy Characteristics
Particle Behavior
Atoms Combine to Make Something New
100
All matter is made up of this.
What are particles (atoms)?
100
To grow in size, amount, or volume; to get bigger.
What is expand?
100
Name 3 characteristics of an apple.
What is (ex: red, soft, edible, shiny, smooth...)
100

Particles move this way when they are heated (faster/slower).

What is faster?

100
2 Hydrogen atoms combined with 1 Oxygen atom makes this.
What is water (H2O)?
200
The particles in matter are always doing this.
What is moving?
200
To shrink down in size; to get smaller.
What is contract?
200
The reason water and glue have different characteristics:
What is they are made up of different particles (atoms)?
200

Particles move this way when they are cooled (faster/slower).

What is the slower?

200
Sodium combines with Chlorine to make this.
What is salt (NaCl)?
300
The smallest part of an element is called this.
What is an atom?
300

This is how particles move when they are heated. (closer together or farther apart)

What is further apart?

300
This is why the brass plaque popped out of the wooden frame in the Science Court video.
What is... the brass expanded faster and more than the wood frame when they were heated by the hot spotlights.
300

Particles in this state are moving the fastest.

What is a gas?

300

A special kind of molecule made up of different kinds of atoms is called this.

What is a compound?

400
Two or more atoms that are tightly joined together are called this.
What is a molecule?
400
This is an example of two materials that expand different amounts or at different rates when heated.
What is (Mrs. Wade will accept many examples...) ex: -brass expands more than wood - the metal lid on a jar expands more than the glass jar
400
This strip is made of 2 or more metals that have been fused together. (Mrs. Wade demonstrated how when heated, the metal bends because one metal expands more than the other.)
What is a bimetal (bimetallic) strip?
400

Particles in this state are moving the slowest.

What is a solid?

400
2 Hydrogen atoms combine with 2 Oxygen atoms to make this.
What is hydrogen peroxide (H2O2)?
500
This substance is made up of only one type of atom.
What is an element?
500
This drawing shows particles in cooler matter and then matter that has been heated:
(Drawing should show particles stay the same size. The particles move further apart, so the matter expands.)
500
In what device might you find a bimetallic strip?
What is in a thermostat?
500

Particles in all states are always doing this.

What is moving?

500
1 Carbon atom combines with 2 Oxygen atoms to make this.
What is carbon dioxide (CO2)?
