Jim Gillette and Sherry Williams examine a precipitate, which remains after a chemical solution evaporates. Dave Wehe and Jerry Kropp use the weight of a solution to calculate its chemical composition. - W-vt'5 ik:' ' ,4 Chemistry uses intensive research Chemistry at Seaholm is more than the study of evil-smelling chemicals. It is the prerequisite for anyone interested in pursuing the study of science, iust as algebra is necessary for anyone studying mathematics. Chemistry is taught using a type of intensive research that teaches the student basic scientific procedures, as well as a great deal of chemistry. There are two main areas of study. One deals with the nature of chemical substances, while the other delves into the reasons and effects of chemical changes. But first it is necessary to become acquainted with the scientific methods that will be used throughout the year. For instance, knowing how to use the slide rule is a must, since students will later be dealing with complicated chemical calculations. One of the first experiments, the sample observation of a burning candle, introduces the student to the necessity of obiectivity in science. Learning the nature of chemical substances goes far beyond apparent characteristics. Valences, oxidation factors, ionic pressure, kinetic speeds and solubility are things that must be taken into account. To understand what goes on in an experiment, the exact nature of the substance being used must be known. The experiments that deal with chemical changes pursue the questions of why and how. Performing an experiment that results in the production of hydrogen from hydo- chloric acid are Bob Maker, Dick O'Reen, Stephanie Sawdey and Ruth Dennis. 23 S . 32' . it

Tom Malone and Brian Devaney observe Tom Quarton as he prepares hydrogen. i 1 i e By putting her hands on a generator, Cheryl Metcalfe shows the effects of static electricity. T L Compreltending physical world involves study of the universe Why is perpetual motion impossible? What. is inertial law? These and other questions are answered in the physics course. The principles, which are vital for an understanding of physics, are dealt with first as a basis. Then students go o'n to learn about light, sound, heat, mechanics, electricity and the relationship between them and other forces in the uni- verse. Much of this course depends on the lab sessions in which students can actually see Newton's Laws or nuclear or atomic physics illustrated. Physical science is another popular course. This is for the student who wants a lab science but no specialization. As a unified approach to chemistry and physics, it offers a good general background. Another course, senior science, is similar to physical science in that it too is simplified physics and chemistry. In their physical science class, Shelly McClean and Helen Lombardo learn to prepare potassium chlorate.
