Matter
What is matter made up of?
smaller particles)
Cutting a piece of paper is an example of a _______change
Physical
When two or more different substances are mixed, a new substance may be formed. This is called a __________ change.
Chemical
The scientific study of what matter is made of and how it changes is known as what?
(chemistry)
People can use (________) to describe and identify matter.
Properties
What is a characteristic of particles?
They are too small to be seen
During a physical change, the total _______ of matter is conserved.
Weight or Mass
When a chemical change occurs, the total weight of matter does what?
(stays the same/is conserved/no matter is gained or lost)
Matter is made up of particles too small to be seen. These are called what?
atoms
Describe solubility
The Ability of a substance to dissolve
What is an example of a particle that makes up matter?
air
What are the three states of matter?
(liquid, gas, solid)
—What is an example of a chemical change?
cooking or baking, rusting, burning paper, rotting a banana
Matter made up of a single type of atom is called a what?
eelement
Name three properties of matter.
color, hardness, reflectivity, electrical conductivity, thermal conductivity, magnetism, and solubility
Blowing up a balloon can be used as a _______to show that particles exist.
Model
In your own words, describe a physical change.
A type of matter can change physically while remaining the same type of matter.)
How do you know when a chemical change has occurred?
formation of gas, change in color, change in odor, change in temperature, emission of light, and formation of a precipitate
All of the atoms of an element are what?
Identical
Explain how evidence can be used to describe matter.
Scientists collect evidence through observations, measurements, and experiments to build a complete description of matter.
—What is an example of evidence that can be used to explain that matter is made of particles too small to be seen?
inflating a balloon, evaporating liquids, and dissolving a substance.
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
—What kind of evidence of a chemical change would you expect to find when you burn a match?
(Accept either change in temperature or emission of light.
Describe a molecule
Molecules form when atoms join together with other atoms
