Reviews the ecological dangers of certain types of detergents, and the action taken by government agencies and detergent manufacturers to alleviate the problem. Describes classroom activities and instructional procedures designed to illustrate detergent characteristics and the effects of detergent pollution. (MLH)

Discusses ways in which student exercises with disposable beverage containers can illustrate, by analogy, such things as rock surveys, animal territoriality, energy conservation, and mechanical weathering. (MLH)

Describes the materials and laboratory techniques for the study of food chains and food webs, pyramids of numbers and biomass, energy pyramids, and oxygen gradients. Presents a procedure for investigating the effects of various pollutants on an entire ecosystem. (GS)

Condensed from "The Instructor, Volume 78 (December 1968), 64-65.

Described are about two dozen laboratory experiments, demonstrations and class discussions intended to supplement secondary school biology curricula with energy-related learning activities. Concepts examined in these materials include photosynthesis, energy from biomass, feeding relationships, pyrolysis, and respiration. Lessons contain notes to…

Presented are seven folios of energy activities for elementary school students. Each set is devoted to different energy-related themes: (1) What is energy? What does energy do? Where does energy come from?; (2) We find energy in many places; (3) Energy does all the work in the world; (4) The Earth's energy sources are limited; (5) Energy changes…

Described in this guide are the emergent and semiemergent plants most likely to be found in inland and coastal marshes. The guide is intended for field identification of marsh plants without resources to technical botanical keys. The plants are discussed in seven groups. Within each group the kinds which resemble one another most closely are next…

THIS PROJECT CONSISTED OF DEVELOPING AND TESTING MATERIALS DESIGNED TO TEACH THE PROCESSES OF SCIENTIFIC INQUIRY TO BEGINNING BIOLOGY STUDENTS. MATERIALS CALLED "SPRINGBOARDS FOR DISCUSSION" AND DESIGNED FOR PRESENTATION BY USING THE OVERHEAD PROJECTOR AND MAGNETIC TAPES WERE USED IN INSTRUCTION. MATERIALS OF THE FOLLOWING TYPES WERE…

Presented are 29 activity cards designed for use with the Elementary Science Study (ESS) program. Each card describes an experiment on one aspect of water flow such as siphoning, methods of removing water from a container, aspirators, floats, and water behavior in various tubing linkups. Activities are intended for individual or small group study;…

This picture book was designed to be used with an Elementary Science Study unit that provides opportunities for students in grades 4-6 to study animal tracks. Shown within this book are numerous examples of tracks, including those of tires, human beings, animal tracks, and others in various media, such as snow, sand, mud, dust, and cement. (CS)
