Students need practice in proposing hypotheses, developing experiments that will test these hypotheses, and generating data that they will analyze to support or refute them. I describe a guided-inquiry activity based on the "tongue map" concept, appropriate for middle school and high school students.

This guide contains Parts III and IV of the students' guide to the first year of the three-year integrated biology, chemistry, and physics courses being prepared by the Portland Project Committee. Part III is titled "Energy and Work" and Part IV is titled "Ecology." (GR)

A small pond in a schoolyard provided year-round biological activities for children. As seasons changed, concepts and life relations also changed. Besides microscopic organisms in water, children learned about microscopic algae, detritus, and food chains. Concepts of predator-prey relationships and of ecosystems were successfully developed.

Nuffield Secondary Science is a set of tested materials from which teachers can prepare courses for students in grades 9-11 (approximately) who do not intend to major in science. The materials are designed for British secondary schools. The Teachers' Guide to the entire set of Themes is described in SE 015 440. Each Theme is a teachers' guide to a…

Describes the use of a simulation lesson which is written in TUTOR language for the PLATO computer for the purpose of separating a mixture of four ions with known identity. Indicates that students have more freedom to experiment than in laboratories in other traditional computer-assisted programs. (CC)

Presented is a report of a program of the American Society for Metals, designed to introduce materials science principles via solid state chemistry into high school chemistry courses. At the time of the inception of this program in the mid-sixties, it was felt that high school students were not being adequately exposed to career opportunities in…

Nuffield Combined Science is a set of tested instructional materials prepared in an "attempt to recapture the unity of outlook and consistency of method which belong to the whole of science and which enable us to make reasoned statements about the world we live in." The student-centered activity-based materials integrate the traditional…

In this third volume of the United Nations Educational, Scientific and Cultural Organization's (UNESCO) series on "New Trends in Chemistry Teaching," a total of 29 papers originally published during the period from 1969 to 1971 in leading chemistry-teaching periodicals of the world is compiled for the purpose of promoting information exchange. The…

Included in this set are the teacher's guide and the four student laboratory manuals for the seventh grade science program, "A Search For Structure." The program has three phases, each consisting of student-centered, investigative activities. There are two subject area options in phase one: option A, Rocks and Minerals; and option B, Insects. The…

Discusses the importance of the tactile sense in the learning process of young children. Describes a program in which children are able to handle natural history objects provided by a museum. (JR)

This document presents an explanation, illustration, and evaluation of a Students Toward Environmental Participation (S.T.E.P.) Project at Rutherford High School in Bay County, Florida. The main objective of this S.T.E.P. Project was to train high school students to teach environmental awareness activities to elementary students. This booklet…

Describes a home-based supplementary science program for elementary school age children. The program emphasizes process skill application, simple equipment, and the use of parents as experiment advisors. (CP)
