Daily TAKS Connection: Convection, Conduction, and Radiation

1
Daily TAKS ConnectionConvection, Conduction,
and Radiation

• IPC(6) The student knows the impact of energy
  transformations in everyday life. The student is
  expected to
• (B) Investigate and demonstrate the movement of
  heat through solids, liquids, and gases by
  convection, conduction, and radiation.

Foldable Instructions

• Instructions
• Hot Dog fold paper
• With the paper turned horizontally, make 3 cuts
  from top to bottom stopping at the fold.
• Label 1 flap Conduction, 1 flap Convection, and 1
  flap Radiation.

• Materials
• Paper
• Scissors
• Pen
• Colored pencils/crayons

3
Foldable Completion

• Using the Foldable Cut-Out Sheet, cut-out the
  definitions and pictures.
• Glue the picture and the definition of each of
  the types of heat transfer on the inside of the
  flap that it matches.

4
Foldable completion, contd.

• Using the Foldable Cut-Out Sheet, cut-out the
  solid, liquid and gas representations.
• Glue them on the inside of your foldable on the
  portion that has not been cut.
• Label each picture as either a solid, liquid, or
  gas.

5
Quick Review

• Is a solid a fluid? NO!!
• Do solids have fluid motion? NO!!
• VERY important only fluids can transfer heat by
  convection

6
Question 1

• The primary way liquids and gases (fluids)
  transmit heat is by the process of
• A. reflection
• B. conduction
• C. radiation
• D. convection

7
Question 2

• Heat convection occurs in gases and liquids.
  Heat convection does not occur in solids because
  solids are unable to
• A. absorb heat by vibrating
• B. transfer heat by fluid motion
• C. emit radiation by reflecting light
• D. exchange heat by direct contact

8
Question 3

• In winter the air just above the top bunk of a
  bunk bed is warmer than the air just above the
  bottom bunk because warm air rises. Which of the
  methods of heating causes this difference in
  temperature?

9
Question 4

• Name the method of heating that best describes
  each of the following
•  
• A satellite is warmed by sunlight.
• Butter melts on warm bread.
• A ceiling fan cools a warm room.

Insulators and Conductors Notes(Write these in a
T-Chart format next to the pictures of the States
of Matter)

• conductors
• allow heat to transfer readily
• Black improves absorption of infrared radiation
  (heat)
• Ex metals are good conductors of heat painted
  black are even better
• insulators
• do not readily allow the transfer of heat
• Ex glass and plastic are good insulators of heat

11
Now Apply Your Knowledge

• determine whether a substance is a good conductor
  or insulator based on data provided
• FYI
• (Write this in your T-Chart!)
• good insulators dont allow heat loss/gain
  therefore little or no temperature change
• good conductors do allow heat loss/gain
  therefore a large temperature change will take
  place

12
Insulators and Conductors Classifying Game

• Use the cards to determine which objects Conduct
  Heat or Do Not Conduct Heat
• Place each object under the correct heading.

13
Question 5

• Which container is a better insulator? A better
  conductor? Why?
