The work describes an analogy-based small oscillations analysis of a standard static equilibrium lab problem. In addition to force analysis, a potential energy function for the system is developed, and by drawing out mathematical similarities to the simple harmonic oscillator, we are able to describe (and experimentally verify) the period of small…

EIGHTEEN DEMONSTRATIONS ON THE SUBJECT OF SOIL AND WATER CONSERVATION ARE PRESENTED. THESE DEMONSTRATIONS UTILIZE SIMPLE AND INEXPENSIVE EQUIPMENT AND ARE SUITABLE FOR CLASSROOM OR OTHER GROUP USE, ALTHOUGH THEY WERE DESIGNED FOR 4-H CLUBS. LISTED ARE THE EQUIPMENT AND MATERIALS NEEDED, PREVIOUS PREPARATION, STEPS IN THE DEMONSTRATION, AND…

Describes a project to improve the science curricula and the science teaching skills of instructors in Houston-area two-year colleges in such a way that the program can be replicated in other locations. Two-year college faculty members were teamed with faculty from universities. (PR)

INCLUDED IN THIS MANUAL WRITTEN FOR SECONDARY SCHOOL AND COLLEGE TEACHERS ARE DESCRIPTIONS OF DEMONSTRATION MODELS, EXPERIMENTS PERTAINING TO SOME OF THE FUNDAMENTAL AND APPLIED METEOROLOGICAL CONCEPTS, AND INSTRUCTIONS FOR MAKING SIMPLE WEATHER OBSERVATIONS. THE CRITERIA FOR SELECTION OF TOPICS WERE EASE AND COST OF CONSTRUCTING APPARATUS AS WELL…
