NOVA SCIENCE UNIT 14.
THE MAJOR CONCEPT OF THE UNIT IS THAT SOMETHING MUST BE DONE TO PARTICLES IN ORDER TO STUDY THEM. ATOMS ARE COMPOSED OF TWO KINDS OF CHARGED PARTICLES--PROTONS AND ELECTRONS. ANY DIFFERENCE IN THEIR NUMBERS RESULTS IN A CHARGED BODY. IF ENOUGH CHARGED BODIES ARE PRODUCED, THEY WILL AFFECT CHARGE DETECTORS. CONCLUSIONS CAN BE DRAWN FROM THE RESULTS. STUDENTS ARE ENCOURAGED TO BUILD SIMPLE DEVICES FOR USE IN DETECTING THE PRESENCE OR ABSENCE OF ELECTRONS. EXPERIMENTS ARE PERFORMED ON NONCONDUCTORS, WITH BALLOONS OR BY BOILING, TO DETERMINE THE CHANGE, AND STUDENTS ARE LED TO NOTICE RELAIONSHIPS BETWEEN THE EXPERIMENTS AND TO PERFORM OTHER EXPERIMENTS. A SIMPLE ELECTRON ACCELERATOR IS USED IN THE CLASSROOM. THE SPRINKLING OF SALT INTO A FLAME, THE USE OF A SPECTROSCOPE, AND THE EXAMINATION OF FLOUROCENE IN A TEST TUBE MAKE STUDENTS AWARE THAT EACH COLOR OF LIGHT IS A SPECIAL ENERGY OF LIGHT. THE STUDY OF ENERGY CHANGES IN THE POSITION OF ELECTRONS IS CALLED QUANTUM MECHANICS. THE RECORDING OF DATA IN ALL EXPERIMENTS IS STRESSED.
