II. Introduction of new topic:
• Heat transfer
Everything is made of molecules.
When molecules gain energy they move faster and create more heat.
(The faster the molecules move the hotter they are)
Solid
Molecules move very slowly! They are close together.
liquid
Molecules move faster and are more spread apart.
Gas
Molecules move very fast! They are very spread apart.
Pair/Share 1 (3 min)
Answer the questions:
1 What happens to molecules as you add heat?
They move faster
2. Are the molecules of water moving faster or slower in cold water?
Why? Slower. Because of temperature.
3. Evaporation is when a Liquid turns into a gas.
4. Freezing is when a liquid turns into a solid.
Heat Is the transfer of thermal energy from a hotter object to a cooler
one until both objects are the same temperature.
(You can not transfer cold or give someone cold)
Pair/Share 2 (3 min)
1 Which direction does heat transfer? From warmer to cooler
2 When you touch something cold which direction is heat being
transferred? Why? From object to hand, because the object is cooler.
3 Explain why you feel cold when you touch something that is cold.
Because of heat transfer.
3 ways that heat is transferred within the atmosphere
• Radiation
• Conduction
• Convection
The first method of heat transfer. How does heat energy get from the
Sun to the Earth?
RADIATION The direct transfer of energy by infrared electromagnetic
Waves.
What creates electromagnetic waves? Sun, fire, light bulbs.

What are three different things that create electromagnetic
radiation?
Sun, fire, light bulbs.
Conduction The direct transfer of heat from one substance to another
substance that is touching.
Convection The transfer of heat by movement of a fluid (liquids and
gases).
III. Review.
Heat transfer from a hotter object to a cooler object until both objects
are the same temperature.
3 types of heat transfer
• Radiation – electromagnetic waves
• Conduction – touching
• Convection through a fluid (liquid or gas)
• All 3 work together to heat the troposphere but Convection
causes most of the heating.
