* What happens to the temperature if I add ice
cubes to a glass of soda?
* Write your answer down in your notes.

* How many of you wrote that the ice cubes
make the soda cold?

* What if I told you that ice cubes do not make
soda cold?
* In fact, it is the soda that warms up the ice
cube!

* When will the heat transfer between the soda
and the ice cubes stop? Why?
* Write your answer down in your notes.

* How many of you wrote, “When the ice has
finished melting?”
* Please share your answers.

* When the ice has finished melting, the
temperature has increased.
* When the ice was added to the soda, the
temperature of the soda decreased.
* The ice continued to melt until the soda and
the ice reached the same temperature.
* This is because heat transfer continues until
both objects have reached the same
temperature.
* When the two objects have reached the same
temperature, this is called Thermodynamic
Equilibrium.
*
*
* In your notes, number a set of lines 1-5.
* You will be shown a series of pictures. The
pictures will show objects between which heat
transfer will occur.
* On your paper, draw an arrow showing which
direction the heat will transfer in.

Cool Air

Since the skin has a higher
temperature than the air, the skin
transfers heat to the air around it,
making itself cooler.

Lava
Since the lava has a much
higher temperature than the
mountain, it transfers heat to
the mountain wherever the
two make contact.

Chair
Student
The typical human body is around 98.6
degrees Fahrenheit, whereas a chair is
usually room temperature, 75 degrees
Fahrenheit. When the two come into
contact, heat transfers from the student to
the chair. That’s why the chair feels cool.

Apollo the Lizard
Heat will transfer from the Sun
to the lizard. There is nothing
on Earth hotter than the Sun,
and besides: lizards are
exothermic!

Light Bulb

When a light bulb gives off light, it
also gives off heat. This heat warms
up the surrounding air. If you place
your hand near a light bulb (don’t
touch!), you will feel the heat.

* Step 1: Partner A looks at question one and shares
the answer with partner B.
* Step 2: Partner B either approves of the answer, or
guides partner A to the correct answer.
* Step 3: Once an answer is agreed upon, Partner A
asks, "May I write it down?"
* Step 4: Partner B either agrees or provides further
coaching until a correct answer is agreed upon.
* Step 5: Partner A picks up the writing utensil and
writes down the answer. Then Partner A hands the
writing utensil to Partner B, and the steps repeat.
* If these instructions are not followed, you will
complete the work by yourself.
