What is color change, heat, bubbles, and odor?
300
This type of mixture is one where the combined substances can be seen in the mixture. Example: Salad
What is heterogeneous mixture?
400
Matter that is made up of molecules that are not as tightly packed as solids. This state of matter takes the shape of whatever container it is in.
What is a liquid?
400
Ice being solid enough to ice skate on is an example of this state of matter
What is a freezing?
400
A science tool used to measure the volume of liquids.
What is a graduated cylinder?
400
Changes that can go back to the original form.
What is reversible change or physical change?
400
What is this measurement?
What is 38.5mL?
500
Matter that is made up of molecules that are loosely packed that move around. This type of matter also takes up the shape of whatever container they are in. This type of matter is often invisible.
What is a gas?
500
Dew is a result of water vapor making this change from a gas to a liquid
What is a condensing?
500
The relationship between mass and volume of an object. (mathematically calculated V= M/V)
What is density?
500
Which are the chemical changes:
1-Baking a cake 2-Butter melting
3-A log burning 4-Film canister rockets
5-Paper being torn 6-fireworks exploding
What is 1, 3, 4, and 6?
500

DOUBLE JEOPARDY
What is an atom?
600
Matter that is made up of tightly packed molecules that have a definite shape.
What is a solid?
600
Boiling is a an example of state of matter change from liquid to gas
What is vaporization?
600
A characteristics of matter that can be measured and helps describe it. (Shape, size, color, hardness, density, volume, mass, texture)
DOUBLE JEOPARDY
What is property?
600
Changes that can not go back to the original form.
What is a irreversible change?
600
What is the chemical formula for carbon dioxide?

700
This means the amount of matter stays the same, even when matter changes form.
What is a conservation of matter?
700
A substance's state of matter is most directly affected by this
What is temperature?
700
transforming something from one substance to another, like the burning of paper or rusting of metal
What is a chemical change?
700
When chemical changes take place, no new matter is produced or destroyed; molecules are just moved around to create new substances.
DOUBLE JEOPARDY
What is Law of Conservation of Matter?
700
DOUBLE JEOPARDY
What is the name of this table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.
