How Can Substances Be Identified?
How Do Scientists Know when Substances Change?
What Causes Substances to Change?
Substances Changes and Weight
100

Particles in this state of matter are closely packed together and vibrate in place

What is "solid"?

100

This is created when one substance is dissolved into another

What is a "mixture"?
100

This process is when one or more substance are changed into a new substance

What is a "reaction"?

100

Most substances do this when heated

What is "expand"?

100

This cannot be created or destroyed

What is "matter"?

(Will also accept What is "energy"?)

200

All matter is made up of these smaller "pieces" of matter

What are "particles"?

200

This term describes the characters of a substance

What are "properties"?

200

This term describes when a substance changes from one state of matter to another, but remains the same substance

What is a "state change"?

200

Most substances do this when cooled

What is "contract"?

200

True or False?

When a new substance is created following a reaction, some of the matter is gone forever

What is "false"?

300

This state change happens when matter moves from solid to a liquid

What is "melting"?

300

This property describes how easily a substance can be shaped or manipulated without breaking/shattering

What is "brittleness"?

300

When you add baking soda to vinegar in an open container, you lose some of the weight of the substances because of this

What is "gas formation"?

300

This type of reaction causes a glowstick to glow when "snapped"

What is a "chemical reaction"?

300

This term describes matter being kept at the same total amount before and after a reaction

What is "conserved"?

400

Particles in this state of matter are moving faster and spread out in all directions

What is "gas"?

400

This property describes how well light can bounce off of a substance

What is "reflectivity"?

400

What is one piece of evidence that a reaction has taken place in this picture? 

Light, color change, sound (energy released), gas formation (smoke)

400

Some metals have chemical reactions with oxygen over time causing this new substance to form

What is "rust"?

400

If you can contain the gas created by this reaction in a balloon, the law of conservation tells us that the weight of the substances after the reaction will do this


What is "stay the same"?

500

This state change happens when matter changes from a gas to a liquid

What is "condensation"?

500

This property describes how well a substance can dissolve into another substance

What is "solubility"? 

500

Two of these properties change during the reaction of wood burning

What is "color", "solid formation (ash)", "gas formation", "energy change (light, heat, sound)"?

500

The temperature of a substance will increase when you shrink the space it is being contained in because you are increasing this 

What is "pressure"?

500

Scientists no longer spend time testing whether matter is conserved or not because it has been proven enough times that it is now considered a "scientific ______"

What is "law"?
