Chemistry students Jaidyn Moore and Zyriah Meadows experimented with dry ice, solid carbon dioxide, in order to observe its sublimation. Tenth grader Dylan Calhoun is holding the bubbles full of carbon dioxide vapors that resulted from adding the dry ice to a beaker of dish detergent water.
In another lab, the physical science students “raced” battery-operated dune buggies as a culmination to their velocity studies. They used stopwatches to measure the time it took for the buggies to travel 5 meters. They hypothesized the velocity, calculated it, and then found their percent error.
