1
Create your foldable like this one: 1.Grab TWO pieces of paper 2. Fold in half, with one inch between 3. Use TWO staples only 4. Cut the two bottom flaps in half 5. Label like this picture:
2
AKA: Conduction, Convection and Radiation Heat Energy and Heat Transfer
3
Part 1: For part 1, You will be taking notes from video clips and answering discussion questions. Write your notes the top of the second tab of your foldable. You can write on the back of the top flap, too!
4
Introduction to Heat
5
Introduction to Heat: Discussion What is necessary for a hot air balloon to float through the air? What is the use for heat in a power plant?
6
The Sun’s Energy and Heat
7
The Sun’s Energy and Heat: Discussion Why is The Sun so important when it comes to heat energy? Why does all life rely on The Sun’s energy to exist? How do you use The Sun’s energy to survive?
8
Defining Temperature
9
Defining Temperature: Discussion What is the difference between heat and temperature? What is heat determined by?
10
Measuring Heat
11
Measuring Heat: Discussion What are the two units most commonly used for measuring heat? What is the first kind most commonly used for? What is the second kind most commonly used for?
12
Part 2: For part 2, use the labeled tabs of your foldable!
13
Conduction
14
Conduction – heat transferred by particles colliding into one another, such as in a metal. Transfer of energy by touch Not an effective transfer in a gas. Primarily used with solids
15
Conduction: Discussion What ways have you used or experienced conduction? Why does conduction work well for solids and not gases or liquids?
16
Convection
17
Convection – heat transferred by the circulation of a fluid (liquid or gas), such as in a heating system at home or boiling water. Hot air rises cool air falls
18
Convection: Discussion How does convection relate to hot air balloons? What does this have to do with density? How have you used convection in your house?
19
Radiation
20
Radiation – heat transferred by the flow of electromagnetic radiation, like heat felt from the campfire. Radiation is the only type of heat transfer that can happen in a vacuum. Heat transfer through waves
21
Radiation: Discussion Why can radiation happen in a vacuum? How have you used or experienced radiation before?
23
Insulation: Put this in Part 1
24
CONDUCTION: the transfer of energy through matter by direct contact of particles. This can happen in solids, liquids and gases. CONVECTION: the transfer of energy because of the movement of bulk masses of particles. This can happen only in liquids and gases - not in solids. RADIATION: the transfer of energy by electromagnetic waves. Energy can move by radiation in air like the heat from your electric stove top, or in the vacuum of space the way the Sun heats the Earth. In radiation, the energy does not have to transfer through mass (particles). Review: Heat Transfer
25
Review: Card Game You will work with a partner for this activity. You need a bag of gold cards. Pull out the cards that say: Conduction, Convection and Radiation. Match the definitions with the names. Then, match the examples with the type of heat transfer they represent.
