Anything that has mass and takes up space is known as what?
Matter
What is matter made up of?
Smaller particles
Cutting a piece of paper is an example of __________ change.
Physical
When two or more different substances are mixed together, 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 physical change, the total __________ of matter is conserved.
Weight or mass
When chemical change occurs, the total weight of matter does what?
Stays the same, is conserved, or no matter is gained or lost
Matter is made up of particles to 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, element, molecule, etc.
What are the three states of matter?
Solid, liquid, and gas
What is an example of chemical change?
Cooking or baking, rusting, burning, rotting, etc.
Matter made up of a single type of atom is called what?
Element
Name three properties of matter.
Color, hardness, reflectivity, electrical conductivity, thermal conductivity, magnetism, solubility, etc.
Blowing up a balloon can be used as a __________ to show that particles exist.
Model
In your own words, describe a physical change.
ie: 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 a gas, change in color, change in odor, change in temperature, emission of light, or formation of a precipitate
All atoms of an element are what?
Identical or the same
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.
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
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.
Change in temperature or emission of light
Describe a molecule.
Molecules form when atoms join together with other atoms.
