Solve a problem by designing a device that uses thermal conductors or insulators. You can come up with your own problem to solve (preferred) or work on one of these problems: Campers want a travel cup that uses a cold pack to cool a liquid. Design the outer part of the cup that keeps the drink cold once it has been cooled down.
Campers want a travel cup that can use a cold pack to cool a liquid. Design the inner compartment that holds the cold pack and conducts heat from the liquid in the cup.
People who like to work while sitting on couches or comfy chairs find that laptops are too hot to be held on their laps. Design something for the bottom of a laptop that conducts heat away from the lap and the laptop.
An animal refuge routinely moves turtle eggs to a new location. Typically buried in the ground, the eggs have to be kept at the same temperature as the ground while they’re being moved. Design an insulated container to keep the eggs at the correct temperature.
Storing a cell phone in a cold environment is detrimental to its battery life. Design a “coat” or a container for a cell phone to shield it from cold weather and prolong its battery life.
Describe the device that you plan to design, build, and test. Will your device use thermal conductors or insulators?
