This book is written for children ages 5 through 10. Part of a series designed to develop their curiosity, fascinate them and educate them, this volume explores the natural history of animals that live underground. Animals included are porcupine, insects, earthworm, mole, badger, rabbit, prairie dog, and beach animals. (YP)

This workbook contains 47 activities and exercises which reinforce lesson topics found in the grade 3 science textbook. These lesson topics, presented in nine sections in the textbook, focus on such areas as: (1) solar energy, electricity, and light; (2) solar system, planets, earth motions, and phases of the moon; (3) gravity, rocks, and erosion;…

Describes materials and techniques suitable for class fieldwork on the ecology of the cyanogenesis polymorphism of white clover. Details of a school trial are presented and discussed. (Author/EB)

Describes an inquiry appraoch in which tree growth-ring analysis is used to determine the age of a tree, trace flood history, and investigate environmental effects on tree size. (MLH)

This document provides a laboratory manual for use by secondary level students in performing consumer-oriented laboratory experiments. Each experiment includes an introductory question outlining the purpose of the investigation, a detailed discussion, detailed procedures, questions to be answered upon completing the experiment, and information for…

Describes a demonstration for measurement of biophysical signals produced by the human body. The signals, after amplification, could provide acoustical feedback through a voltage-controlled oscillator (VCO), or they could be seen either with an oscilloscope or a high speed chart recorder. (GA)

Described are a method of cultivating Euglena, a method for presenting and solving mole equations, and a design of a simple solar collector. (SL)

Reviews a fictitious case study used as a values-clarifying teaching strategy for students of human genetics and bioethics. (SL)

Describes experiments on the properties of bile salts in teaching physical chemistry for biologists. (SL)

Describes a project for junior high and senior high school students designed to safely preserve hard-bodied marine invertebrates. Details the materials and procedures used in this technique. Stresses the use of non-toxic solutions and producing a lifelike specimen. (CW)

Describes how short-term laboratory projects were used to teach population and community ecology to undergraduate environmental science students. Directed students to formulate and implement their own hypotheses and experimental designs. Uses questionnaire results and written reports to assess the contribution of the course to student…

A science laboratory was developed for use by kindergarten through sixth-grade students. The operation of and the types of science activities used in this laboratory are described. (JN)

Described are embryology experiments demonstrating effects of lithium on the nervous system and the use of hypertonic salt solutions to produce exogastrulation in the eggs of Xenopus laevis. (SL)

This book provides opportunities for engaging students in scientific investigations, offering a hands-on approach that encourages students to understand science concepts, gives them ways to apply the concepts, and introduces and reinforces the skills they need to become independent investigators. The basic outline and objectives of each section of…

Discusses the use of a simple apparatus to measure contact angles between a liquid drop and a solid surface which are determining factors of wettability. Included are examples of applying this technique to various experimental situations. (CC)
