The research orientation of the Department of technics, Faculty of Education, University of Hradec Kralove focuses on finding new ways for development of polytechnic and science education. The research is motivated by the fact that children's interest in technical and science subjects is decreasing in recent years in the Czech Republic. The…

Provides directions for a three person rotating reference system. A series of experiments used with the apparatus is also described. (CP)

Instructions are provided for the construction of 4.5 foot diameter planetarium shells. (CP)

Describes the construction of models of two-dimensional surfaces with negative curvature that are used to illustrate differences in the triangle sum rule for the various Big Bang Theories of the universe. (JRH)

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

Describes a circuit (utilizing simple equipment) which can be used to measure the period of a harmonic oscillator. (CP)

Bridges and similar constructions are highlighted in this book of guided lessons and activities for secondary school physics students. This program was developed by the Physics Curriculum Development Project under the auspices of the Physics Curriculum Innovation Committee. Contents include: (1) "Introduction" (presenting a rationale for…

Describes the construction and operation of a short Foucault pendulum, which indicates earth's rotation with less than 2 percent error. The pendulum is suitable for display either in a classroom or hallway. (SK)

This book has been written to help teachers develop the background knowledge and understanding needed to teach science effectively at primary level. It is intended principally as a resource in attempting to set out facts, develop concepts, and explain theories which primary teachers may find it useful to know and understand in order to plan…
