-Heat Transfer interactive-

Introduction: Heat always travels from a ______ object to a ______ object.

 1. Conduction

  a. What substances make good conductors?  

  b. What substances make bad conductors (good insulators)?

  c. What is conduction?

  d. The better the conductor the more _______ heat will transfer.

  e. In conduction, do the substances need to be touching each other?  Explain. 

2. Convection

 a. Draw a picture of a convection current.  Label the red and blue arrows. 

 b. What is convection?

 c. What are some other examples of convection?

 d. Convection is the primary method that heat transfers in _______ and _____.

 e. Which is denser, cold air or warm air?  Explain.

3. Radiation

  a. What effect does the sun's radiation have on the temperature of the house?

  b. What are some other examples of radiation heat transfer?

  c. Radiation can travel through empty space.  True or False?

  d. What is earth’s primary source of radiation? 

B.   http://spaceplace.nasa.gov/beat-the-heat/en/

1.      Can you “beat the heat”?  How far can you go?  Your goal is to make it to Level 10; when you do, show me that you've completed your task.      

C.  http://www.teachersdomain.org/asset/lsps07_int_heattransfer/

- Play the animation for each method of heat transfer; explain what is happening in each animation.  What are examples of each?  Think of an additional two examples of your own for each. 

D. http://www.physics4kids.com/files/thermo_intro.html

1. Read the information on Thermodynamics.

 a. Heat and Thermal Energy: When heat is increased in a system, what else is increased?
 b. Heat of Atoms: Heat is transferred on a molecular level.  Explain.
 c. Heat Movement: What causes heat to move from one system to another?

        Now, take the online quiz on Thermodynamics; write the answers in your notebook.

E. http://www.mansfieldct.org/schools/mms/staff/hand/atomsheat.htm

-       1. Compare/Contrast the molecules of solids at different temperatures and the molecules of liquids at different temperatures. 

-       2. The Kinetic theory of matter states: All matter is made up of ______ and ________ that are constantly ______.

F. http://apollo.lsc.vsc.edu/classes/met130/notes/chapter2/htrans_intro.html

1.    In conduction, thermal energy moves from ____ to ____.

2.    Look at Table 2.2 “Heat Conductivity of Various Substances”

  a.    List in order of high conductivity (conductor) to low conductivity (insulator): wood, water, silver, air, and iron.  
  b. Rank the three states of matter in their ability to conduct heat. 

3.    Give a brief description of atmospheric convection.

4.    What are four examples of radiation?  (The website gives you two; think of two new examples.)

5.    Draw a picture of conduction, convection, and radiation.  Label them correctly.

H. http://www.physics4kids.com/files/thermo_expand.html

        1. What happens to the volume of objects when they absorb thermal energy?

        2. What happens to the volume of objects when they release thermal energy?

I. In the transfer of thermal energy, or movement of heat, how does radiation differ from conduction and convection?

J. Write down observations, thoughts, inferences on each method of heat transfer: conduction, convection, radiation.
