People can use ________ to describe and identify matter?
Properties
During a physical change, the total _________ matter is conserved.
Weight or mass
When in a chemical change, the total weight of matter does what?

Matter is made up of particles too small to be seen. These are called what?
What is an example of a particle that makes up matter?
Air, water…
Describe solubility
The ability of a substance to dissolve
What are the 3 states of matter?
gas, liquid, solid
What is an example of a chemical changes type?
Cooking or baking, rusting metal, burning paper or wood, rotting fruit or food…
Matter made up of a single type of atom is called what?
Element
Blowing up a balloon can be used as a _________ to show that particles exist.
Model
Name three properties of matter
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 a chemical change has occurred?
Formation of gas, change in color, change in odor, change in temperature, emission of light, precipitate formation
All of the atoms in an element are what?
Identical
What is an example of evidence that can be used to explain that matter is particles too small to be seen?
Inflating a balloon, evaporating liquids, dissolving a substance
Explain how evidence can be used to describe matter
Physical properties (color, shape, texture…)
Chemical properties (reactivity, color change, bubble formation, precipitate, temperature changes)
How can you prove the total weight of matter is conserved during a physical change?
Measure matter before and after the change
What kind of evidence of a chemical change would you expect to find when you watch a match burn?
Change in temperature or emission of light
Describe a molecule
Molecules form when atoms join together with other atoms.
