This environmental education program consists of two levels: primary and intermediate. The learning materials are activity based and incorporate process and subject area skills with knowledge and concern for the environment. The program is also interdisciplinary including activities and skills from several areas. The materials in this set for…

Stresses the value of encouraging students to question the results of both obvious and the less obvious scientific activities. A simple science activity built on chemical reactions. (EB)

Describes a heat transfer experiment that demonstrates kinetic behavior using measurements of the rates of cooling and warming of liquids. (MLH)

Describes an instructional unit and objectives on machine design and principles that centers on student-constructed miniature automobiles. (MLH)

Describes some simple activities that teach the use of the metric system. (MLH)

Suggests classroom projects for investigating the diversity of insects. (LS)

Provides a list of sources for weather information. (CP)

As a continuation of SE 516 125 (The Powered Phase), this report provides a detailed analysis of the coast phase of a model rocket trajectory. (CP)

Describes a laboratory experiment in which the experimental data agree well with the empirical law. Demonstrates that transparent materials reflect light. (CP)

Presents experiments, demonstrations, activities and ideas relating to various fields of biology to be used in biology courses in secondary schools. Among those experiments presented are demonstrating the early stages of ferns and mosses and simple culture methods for fern prothalli. (HM)

Presents experiments, demonstration, activities and ideas relating to various fields of physics to be used in physics courses in secondary schools. The use of a programable pocket calculator in A-level physics courses is among the activities described. (HM)

The concept of sloping bedrock strata is portrayed by simple construction of a cardboard model. By use of wires and graph paper, students simulate the drilling of wells and use standard mathematical operations to determine strike and dip of the model stratum. (RE)

Illustrates what children can learn about ecology from observing trees in winter. (BB)
