Upper School students explored the intricacies of uniform circular motion this week, turning their latest physics lab into an engaging investigation of real-world science. To bring the concept to real-world form, Dr. Eric Trumbauer, Upper School AP Physics teacher, installed two flying pig models on the classroom ceiling, their circular motion mimicking that of a ceiling fan. These whimsical pigs became the focal point of the experiment, with Upper School students tasked to measure and analyze their motion to calculate the strength of Earth’s gravitational field. 

Instead of adhering to a prescribed procedure, Dr. Trumbauer encouraged students to design their own methods. “The lab relates to uniform circular motion, but more importantly, this is the first lab where procedures are not provided,” Dr. Trumbauer explained.

Students were given an objective and asked to determine which quantities to measure based on their own calculations, then devise the best ways to measure those for a moving object. With many possible approaches and tools available, they were further challenged to minimize the number of different types of measurements they performed.

Without a set list of measurements or a prescribed method, Upper School AP students had to identify key variables, develop data-collection strategies, and choose the most effective tools for the experiment. This open-ended approach transformed students into authentic investigators—making critical decisions, testing hypotheses, and taking full responsibility for their learning.

The lab atmosphere resembled a professional research environment more than a traditional classroom. Students navigated uncertainty, collaborated with peers, and continually refined their methods. As a result, the investigation of circular motion became a true scientific exploration which encouraged personal initiative, teamwork, and adaptability.
