Title4B10.12 - Thermal Conductivity of Wood vs. Aluminum
Objective

To show how ice will melt faster on an aluminum plate that begins at a cooler temperature than a wood plate that begins at a higher temperature due to the heat capacity.​

StatusAvailable
Assembly Instructions

Attach a thermoprobe to each of the two plates.  Place an o-ring on each plate to contain the melting ice.  Display the multimeters and the plates using 2 cameras.​

Operation Instructions

Begin with no ice on the plates.  Have the students observe the temperatures and ask them which they believe would melt the ice faster.  Then place the ice on the plates and allow the students to observe which melts the ice faster.  The result should be that the aluminum plate melts the ice faster due to the larger thermal conductivityof aluminum over wood.
