D. Summarize the way changes in temperature can be produced
and thermal energy transferred.

01. Define temperature as the measure of thermal energy
and describe the way it is measured.
Brainstorm with the students about ways they could keep
warm in the winter. Write contributions on the board.
Divide the students into groups.
Explain that some ways to keep warm might be better
than others and explain that they will try to determine
which things would be best to help them keep warm.
Heat a pan of water and take the temperature of the
water after it is poured into small jars (like baby food
Have the students make a hypothesis about which material
they think will keep the water the warmest.
Quickly, have each group wrap one of the jars in available
material. Have cotton, wool, polyester, nylon, fur, fat
and other materials available. Put rubber bands around
the jar to keep the material on the jar.
After about 15 minutes, unwrap the jars and take the
temperature of the water.
Have students record the material they used and the
temperature after 15 minutes.
You could then invite the students to see if they can
come up with the best way to insulate using more than
one material. Half of the class could try two materials
to see if that makes a difference. The other half of
the class should try three materials. They might also
try items that are not material, like feathers, down
Have students write a summary of their experiment and
the results they achieved.
After discussion of results, they will find that layering
the material keeps the warmth better than a single layer.
- Finally, a discussion should be held about the best
way to stay warm in very cold temperatures.

Students can go to the NASA Web site or other Antarctica
sites to determine what they should wear if they were going
to the Antarctic. Have them make a list of what clothes they
would wear if they were taking a trip to Antarctica and why
they selected them.
