Karen Antognazzi '82 Ko Richard Armstrong ’82 Experiments. . . Aid in Learning Starting in fall ’78 s cience classes experi- ments concentrated on observation and exploration of new scientific concepts. Stu- dents zeroed in on respiration and digestive comparisons between animals and men. The various Biology classes disected ani- mals in order to gain information about dif- ferent animal systems. They used: fish, frogs, fetal pigs, and crazyfish. In Chemistry, students studied molecular constructions. Experiments with different chemicals and elements helped them observe how chemicals react with different sub- stances. Physics explained laws and theories of the universe. Velocity, acceleration, and centri- fugal force were the laws with which class- mates experimented. Any experiment pushed texts aside and most students preferred to learn by doing rather than by reading. ABOVE LEFT: VANCE Hopkins uses a micrometer to measure copper wire. BELOW: Girls such as Laura King, found that using a micrometer is not as easy as it looks. LEFT: Ken Brown assists Carmen Carrasco in setting up her experiment. Ardel Ken B.
