Presented is a descriptive account of Alessandro Volta's first notable success in 1775, the invention of a unique method of generating electricity. Luigi Galvani's announcement of his theory of "animal electricity" in 1972 is integrated into this interpretation of Volta's discoveries with electricity. Five experiments are described: (1)…

The Laboratory Structure and Task Analysis Inventory (LAI) is an instrument designed to facilitate the analysis of laboratory investigations in secondary school science. It yields a quantitative picture of the kinds of activities required of a student in performing laboratory investigations. The report includes guidelines for the use of the…

The experiments in this manual represent state-of-the-art techniques which should be within the budgetary constraints of a college physics or chemistry department. There are fourteen experiments divided into five modules. The modules are on X-ray fluorescence, charged particle detection, neutron activation analysis, X-ray attenuation, and…

Designed for tenth-grade students, this activity book contains sixty-three electrical experiments. Experiments focus on topics such as the direction of flow of electricity in an electric circuit, comparison of heating effect using different amounts of current, comparison of heating effects of electric current in conductors of different sizes, and…

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…

IN THE BIOLOGICAL SCIENCES DEPARTMENT OF SACRAMENTO CITY COLLEGE, EMPHASIS HAS BEEN PLACED ON A TYPE OF INDEPENDENT STUDY INVOLVING SELECTION, DESIGN, PERFORMANCE, AND REPORTING OF AN EXPERIMENT TO EVALUATE AN HYPOTHESIS FORMULATED BY THE STUDENT CONCERNING A TOPIC OF HIS SELECTION. THE FACULTY HAS DEVELOPED A PROJECT SELECTION FORM, WITH…

This student fieldbook provides exercises for a three-week course in limnology. Exercises emphasize applications of knowledge in chemistry, physics, and biology to understand the natural operation of freshwater systems. Fourteen field exercises include: (1) testing for water quality; (2) determination of water temperature, turbidity, dissolved…
