CAN CHALLENG

It’s time for the…

In this activity, you will use your (now vast) knowledge of thermal conduction and insulation to construct an insulating case for a standard 355 mL soda can. The soda can will be placed in the insulator that is already mostly immersed in ice water. It will then be filled with 100mL boiling water and a thermometer will be inserted. When the temperature reaches 70⁰C, the insulator will be closed and a stopwatch will be used to time it for 20 minutes.

RULES

Your insulating container may not be more than 10 cm x 10 cm x 20 cm. We will measure it to make sure that it is up to specification

RULE #1

You may not use any outside sources to heat the water once it is in the can!

RULE #2

You will work in pairs that are personally engineered by yours truly. This is for your benefit, trust me.

RULE #3

You must name your contraption. It can be any name as long as it’s appropriate. And you all know what that means.

RULE #4

You may not use something that is already designed to insulate a soda can. Exercise your genius, not your ability to copy someone else’s.

RULE #5

The bottom 4/5s of your insulating container should be water proof.

RULE #6
