Includes an extract from Chemical Age on…

Describes a bulletin board activity that identifies scientific phenomena occurring worldwide during the school year. A map of the world is marked with colored pins as students find news information of places and kind of event (e.g.; volcanoes, floods, crop failures, human epidemics). (CS)

Presents classroom activities for teaching microbiology at the elementary and secondary levels. Activities demonstrate the existence of the microbial world, types of microbes, and their growth needs and effects in nature. (MLH)

Described is a method of utilizing nomographs to increase student interest in mathematical computations, an experiment dealing with freezing water which students can perform at home, and a technique for interdisciplinary lesson planning. (SL)

Described are science experiments which utilize methylene blue to demonstrate the effects of pH, temperature inhibitors, and concentration on enzyme reactions in yeast enzyme systems. (SL)

The purpose of keeping animals in schools and problems encountered in their maintenance are summarized. Two curriculum units, one on fruit flies and one on honey bees are described. Reasons for a widespread negative image of rural studies are discussed and positive outcomes of an environmental science course are presented. (Author/EB)

This book is an extensive integrated unit of study focused on that common and familiar insect--the cricket. In this edition, teachers are given a complete guide and reproducible worksheets for elementary and middle school students. With over 30 different activities on crickets, students learn science content and skills including: (1) Taxonomy; (2)…

This guide is part of a series of curriculum guides for the middle grades that use a special framework to examine and implement standards-based curricula. In this guide, for developing science curricula for the middle grades, a set of critical questions is posed for curriculum decision making that corresponds to a framework of three components of…
