The effectiveness of science experiments often are partly dependent upon the amount of classroom time available for implementation. This factor alone has frustrated many teachers who attempt to complete laboratory assignments in the allotted time period. This document provides experiments that were designed for the middle year in a 3-year biology…

This book contains simple experiments through which students can learn about the properties of energy. These experiments include making a kitchen "volcano," a soda-pop "cannon," and a puffed-rice "scooter." Topics include: energy and work, fossil fuels, solar energy, kinetic energy, potential energy, mechanical energy, heat energy, sound energy,…

This report summarizes the outcomes of the "Colleges Going Green" project that sought to develop a widely applicable core of environmental learning outcomes (curriculum objectives) and illustrative learning assignments and to review activity in colleges and provide guidance on introducing environmental policy. This report also presents a…

This guide contains indoor and outdoor gardening activities for children. The activities teach children how plants live and grow; how the weather, temperature, and seasons affect all living things; how living things come out of seeds and soil; how the birds, earthworms, bees, and toads help in the garden; and how the whole environment works…

Some preschool teachers have expressed concern regarding the lack of science instructional material for students age 2 through the preschool years. This videotape was developed to help fill this chasm in our educational system. It contains activities from students' everyday life such as eating, washing, and playing. These daily processes are then…

Twelve desk-top experiments and demonstrations which illustrate properties of and facts about gas are presented. Each experiment includes: purpose, materials needed, instructions, and a list of facts and properties that have been observed. Several of the activities also include questions for students and items for discussion. The topics of the…

Presents three lapidary activities which have been developed to teach enrichment courses to adults and young people. Described are activities and materials for polishing and shaping rocks. (EB)

Describes in detail the laboratory procedure for studying the process of amitosis in the vegetative cells of Nitella axillaris. (BR)

This field guide is the basis for a five-day, 1000-mile trip through six states and six geomorphic provinces. The trip and the pre- and post-trip exercises included in the guide constitute a three credit course at The Ohio State University entitled "Field Geology for Science Teachers." The purpose of the trip is to study the regional geology,…

Described are two experiments using electronic circuits designed for the activities. The first experiment is Ruchardt's experiment and the second demonstrates the distribution of velocity of electrons. (RH)
