100
The point when a solid changes its state to a liquid.
What is melting point?
100
The movement of energy from warmer to cooler objects and can change the physical state of matter. An example is water to steam.
What is heat?
100
A push or a pull.
What is a force?
100
Unlike electrical charges (positive and negative)___________ each other.
What is attract?
100
The path along which electrical current flows.
What is a circuit?
200
The point when a liquid changes its state to a solid.
What is freezing point?
200
A form of energy that allows you to see objects and can travel long distances through an empty space.
What is light?
200
A force that works against motion by slowing or stopping the object.
What is friction?
200
Does not allow electrical charges to flow through easily. Wood, rubber, and plastic are examples.
What is an insulator?
200
A complete, unbroken path that allows electricity to flow.
What is a closed circuit?
300
The point when a liquid changes its state to a gas and creates steam.
What is boiling point?
300
The bending of light as it passes from one material to another. (Pencil in a glass of water)
What is refraction?
300
The tendency of an object in motion to stay in motion, and an object at rest to stay at rest.
What is inertia?
300
Transfers heat and allows electrical currents to pass through easily. Copper, silver, aluminum, and glass are examples.
What is a conductor?
300
When all charges flow in the same direction, along a single path.
What is a series circuit?
400
How much space a substance take up, and can be measured using a graduated cylinder, cup, or beaker.
What is volume?
400
1. _____________ objects block light from passing through them. 2. ______________ objects allow some light to pass through, but scatters the light so that it is not clear. 3.____________ objects allow all light to pass through.
1.What is opaque? 2. What is translucent? 3. What is transparent?
400
1. The location of an object. 2. The surrounding objects used for comparing.
1. What is position? 2. What is frame of reference?
400
The buildup of electrical charges on an object. It can be caused by rubbing objects together.
What is static electricity?
400
When electrical current flows through more than one path. I is used in building and in your home.
What is a parallel circuit?
500
The amount of matter that makes up an object, and is measured in grams. It can be measured using a pan balance.
What is mass?
500
1. A color that absorbs all light. 2. A color that reflects all light.
1. What is black? 2. What is white?
500
The measure of the distance an object travels in a certain amount of time.
What is speed?
500
When negative charges move fast from your body, and create a small shock.
What is discharge?
500
The north pole of one magnet and the north pole of another magnet will ____________ each other.
What is repel or push away?
