The size of an object is a good example of this kind of property.
What is physical?
100
Boiling water is this kind of change.
What is physical?

This state of matter best describes ice.
What is solid?
200
This is the tool used to measure mass.
What is a balance (or triple beam balance)?
200
This is the point at which a liquid will turn into a gas.
What is the boiling point?
200
Copper's ability to oxidize (and usually turn green) is a good example of this type of property.
What is chemical?
200
When your body creates energy from the food you eat, you complete this kind of change.
What is a chemical change?
200
This is the formula for density.
What is mass/volume?
300
This is the "force of gravity on an object."
What is weight?
300
This is any characteristic of matter you can observe without changing it.
What is a physical property?
300
Flammability, state of matter and temperature. This is the only chemical property in the list.
What is flammability?
300
Melting an ice cube on a hot pan, cooking scrambled eggs, and lighting paper on fire. This is the only physical change from the list.
What is melting ice on a hot pan?

This is the term that describes a gas (like steam) changing into a liquid (like water).
What is condensation?
400
This is the unit for density.
What is grams/centimeter cubed?
400
This is the law that states that the total mass before a chemical reaction is the same as the total mass after a chemical reaction.
What is the law of conservation of mass?
400
Aluminum can be hammered into a thin sheet. This term describes this type of physical property.
What is malleability?
400
You cut your sandwich in half. You take a bite and chew your delicious lunch. Your saliva begins to digest your mouthful of food. This is the one chemical change in the story.
What is "saliva digests the food"?

What is magnetism?
500
In the Pacific Ocean, hot liquid rock (or magma) churns below the earth's crust. The liquid rock erupts from an underwater volcano. The lava is cooled by the water of the ocean, and changes into solid rock. Describe the change.
