Today, students tested their prototypes. We had two tests, one near the start of the period and the other near the end. Groups that were ready to go tested first, followed by those that needed the first part of the period for building time. The mass of their penguin ice cubes was recorded before and after the test. The test itself took place in the Penguin Melter 3000™.

Their houses were in here for a total of ten minutes. The average mass loss was about 4 grams, which is pretty good! Teams will figure out what to optimize about their designs before our final test tomorrow.
