1 Create a trifold Conduction Convection Radiation
Include notes and 2 pictures for each

2 Warm Up Think about: don’t write down
1. What is heat? 2. How does the heat from the sun reach us on Earth? 3. How does the heater in our classroom heat up the air in the room?

3 How does the Earth heat up?
Heat can be transferred in 3 different ways

4 Conduction The transfer of heat from one material to another by direct contact (touch)

5 EXAMPLE OF CONDUCTION A piece of cheese melts as heat is transferred from the meat to the cheese (Contact)

6 Radiation The transfer of heat as waves and can travel through outer space how the sun’s heat reaches Earth microwaves use radiation Fire

7 Examples of RADIATION Fire Heat Lamps Sun

8 Convection The transfer of heat by the movement of a liquid or gas
Hot air rises, cold air sinks A hot air balloon Lava lamps The wind is caused by convection currents

9 Explaining Convection
Convection currents cause the cooler breezes you experience by a large body of water. These currents also cause the movement of magma within the earth.

10 Examples of Convection:
Have you ever noticed that the air near the ceiling is warmer than the air near the floor? Or that water in a pool is cooler at the deep end? Examples: air movement in a home, pot of heating water. Pick one of these examples and draw the circular pattern in your notes. When the water at the bottom of a pot is heated, its particles move faster, and they also move farther apart. As a result, the heated water becomes less dense. A less dense fluid will float on top of a more dense one. Therefore, the heated water rises in the pot. The surrounding cooler water flows into its place. This flow creates the circular motion as seen on the next page, which is known as convection currents.

14 Heat Transfer Conduction, Convection and Radiation

15 Which type of heat transfer?
Sitting by a warm fire A room warmed by a radiator Frying a piece of fish A spoon sitting in a cup of hot coffee A heating lamp Ironing a shirt

16 Which type of heat transfer?
Sitting by a warm fire radiation A room warmed by a radiator convection Frying a piece of fish conduction A spoon sitting in a cup of hot coffee conduction A heating lamp radiation Ironing a shirt conduction

17 What are Insulators? Insulators are materials that do not allow heat to move easily through them.

18 What are Conductors? Conductors are materials that allow heat to move easily through them.

19 Create a T chart Insulators Conductors
Research 5 examples of good insulators and conductors and include a picture for each.

20 Reflect on the many uses we have for insulators and conductors in our everyday life.
