What does thermal energy measure?
What is thermal energy measures the total energy of moving particles?

What are you feeling when you feel the warmth from a light bulb on your skin?
What is radiation?

What is one difference between an insulator and a conductor?
What is an insulator limits the amount of heat that passes through it, and a conductor readily allows heat tp move through it?

Give an example of an insulator and a conductor?
What is something metal, such as a spoon, is a conductor and a piece of marble, the stone, is an insulator?

What is the measure of the average amount of motion in particles of matter?
What is temperature?

How does a radiator heat a room?
What is a radiator uses convection to heat a room? Water is heated and sent through pipes in a room. The pipes lead to radiators that are made of metal. As the hot water moves, some of the heat energy moves through the walls of the radiator to the air of the room. Convection currents then move the air through the room.

What is the substance is cooling down?

What is an insulator?
What is a material that limits the amount of heat that passes through it?

What happens to the motion of particles of particles when an object becomes hotter?
What is as an object becomes hotter, its particles move more quickly?

When particles are packed closely together, what type of substance is it?
What is a solid?

What forms when heated air expands and cooler air sinks below the warmer air?
What is a convection current?

How does radiation, conduction, and convection all work together on Earth's surface? How do they work together on Earth's surface to warm the surface and the air and to cause win and rain patterns?
What is the Sun's energy reaches the Earth through radiation? This causes the surface of the Earth to heat up. Then, the Earth's surface transfers heat into the air. This is conduction. As the air is heated by Earth's surface, convection currents form. As the rising air cools, the water vapor condenses and then falls as precipitation. These convection currents cause Earth's win and rain patterns.
