Before Industry Day, students predicted what features of their cold cups would make them effective, then they tested the cups and collected data to prove how effective they were. To test their hypotheses, scholars poured cold water in their cup and a regular cup, then measured the change in temperature over time and compared the two results.
On Industry Day they presented the whole process to their classmates and visitors from Tacoma Power and TAF. This included reflecting on why their cup worked or did not work.
One group, that heavily used foil in the design of their cup reflected on why their cold cup caused water to heat faster. Their conclusion was that the foil held in heat from light hitting the cup which made it effective at insultation instead of cooling.
First Creek students then used what they learned about thermal energy and building container prototypes to make their final projects.
