Experiments in Phgsics Class Help to Generate Enthusiasm Hair-raising adventures, including ex- perimentation with a Van de Graff elec- trostatic generator, were common to physics classes. Under Mr. Hamerston's guidance, students conducted scientific observations ofthe properties of energy and force. Chemistry classes engaged in experi- ments such as collection of gases and testing of different types of water. A new grading system was initiated, with no penalty for guessing. Slithering around the science depart- ment was Sam the Snake, who, among other creatures, was the subiect of ex- periments and lab reports for biology students. Mr. Dyar, a former teacher at Columbia, ioined the faculty. Thomas Brady Mervin Mikkola, Marlowe Hamerston, and Larry Dyar. Current being registered on an ammeter is measured by Jerry Trupe in fourth hour Physics class. Discovering a new bacteria in Biology ll proves to -be an adventure for Dave Hughes.
