This is the temperature at which a solid changes state into a liquid.
What is melting point?
100
These materials do not readily permit energy to flow through them.
What are conductors?
100
This is a measure of how much space a sample of matter takes up.
What is volume?
100

A student places 4 objects in water. Only one sinks. What does tthis tell you about that object?

It is more dense than water. 

100
Opposite poles on a magnet do this to one another.
What is attract?
200
In this state of matter, the molecules are moving very rapidly.
What is a gas?
200
Wood would be an example of this.
What is insulator?
200
This is a measure of the foce of gravity between Earth and the object.
What is weight.
200

A wooden block and a metal bolt are the same size. The bolt sinks, but the block floats. Why?

The block is less dense than water.

A student tests several objects with a magnet. Only the paper clip is attracted.

What does this tell the student?

A.     The paper clip is made of plastic

B.     The paper clip contains iron or steel

C.     The paper clip has a strong electric charge

D.     The paper clip is heavier than the other objects

B.     The paper clip contains iron or steel

This occurs when materials are spreading out as they get hotter.
What is expand?
300
Metals like copper would be a good example of this.
What is conductor?
300
This measures mass.
What is a balance?
300

A teacher gives students four liquids that form layers in a beaker.

What is true about the top layer?

It has the least density. 

300
On a compass, this is the direction the arrow will always point.
What is north?
400
Cooling causes particles to get closer together and materials do this.
What is contract?
400
This material conducts electricity and heat very well.
What are metals?
400
On the Moon, an object would do this as compared to on the Earth.
What is weigh less?
400

A student predicts that a plastic bead will float.

Which observation supports this prediction?

A.     The bead is smooth and round

B.     The bead is the same size as a marble

C.     The bead is less dense than water

D.     The bead is heavier than a rock

C.     The bead is less dense than water

This describes what would happen if two north poles of magnets were near each other.
What is repel?
