```					                  Teacher Background Conduction Lab with Spoons

Objective:
Students will be able to predict how hot and cold water will affect spoons of different
materials.

Time: Approximately 1 class period

Materials:
2 cups big enough to hold a couple inches of water
Ice Cubes
Metal Spoon
Plastic Spoon
Hot Water
Stopwatch or clock

Procedure:
1. Present students with the spoons and ask them to predict/compare how hot or cold
they feel between their fingers at room temperature.
2. Fill one cup with cold water.
3. Put a metal and a plastic spoon in the water.
4. Ask students to make prediction about how each spoon will feel after being in the
water for 2 minutes
5. Make observations by feeling the spoons and record observations in your journal.
Give explanations
6. Repeat steps 2 – 5 using hot water. (Be careful not to burn yourself when using
hot water)

Conclusion:
Metal Spoon has a high thermal conductivity while a plastic spoon is a low thermal
conductor. Students should be able to discuss the different properties of the spoons and
how they transfer heat.
 What are the differences between the metal and plastic spoons?
 How does the temperature of the water affect the plastic spoon? Metal spoon?
 Predict how the Temp. of the water would affect a wooden spoon? Another
material?
