Click on the demo to launch the simulation.
1) Click on Radiation. What happens to the house when sunlight is added? Why?
2) Click on Conduction. Why does conduction work well in solids, but not in liquids or gases? Turn on the burner. Why does the metal handle get hot?
3) Click on Convection. What happens in the stove when the fire is lit? Why?

a. ________________________________________
b. ________________________________________
c. ________________________________________
d. ________________________________________
e. ________________________________________ (some scientist consider this layer to be part of space)
5) Click on the words “atmosphere” and then click on each layer of the atmosphere to fill in the blanks below:
a. What are the two main gases found in the atmosphere?
1. ________________________________________
2. ________________________________________
b. The troposphere is the ____________ region of the Earth's atmosphere and is where _____________ occurs.
c. The stratosphere contains the ____________________________________ which absorbs __________________. Look at the diagram: ____________________________ and ____________________________ can fly in the stratosphere.
d. As you go higher in the mesosphere, the temperature becomes ____________________. Scientists do not know much about the mesosphere, but they do know that _________________________ burn up in this layer.
e. Much of the _______ and ________________ from the Sun is absorbed in the thermosphere. It is home to the __________________ (Northern Lights). This is created by charged particles that shed excess energy by emitting photons of __________.
f. In the exosphere the atmosphere is very _______________ as it begins to fade into space.
