Describes the inexpensive construction of an uptake volume potometer uptake and loss potometer, and experiments on plants that can be conducted with the equipment. (BR)

Descriptions of plants suited to specific conservation uses under different site conditions in the Northeast United States are presented in this booklet. The plants are classified into categories based on conservation use. These include: (1) plants for disturbed areas; (2) ornamental ground covers; (3) plants for coastal dunes and sandy inland…

Plants that have been identified as stabilizers and beautifiers of coastal dunes are described in this publication from the Soil Conservation Service (SCS). After years of tests and field trials, the SCS has singled out 43 plants as having good potential for dune revegetation based on their characteristics for erosion control, frequency of…

This field guide was especially developed for Water Watch--a public participation program in Kentucky that encourages citizens to adopt a stream, lake or wetland, and then gain hands-on experience in protecting and enhancing their adopted water resources. Understanding the relationships between life and the environment helps people to appreciate…

Presented are some science activities that children can perform using fallen leaves. (PEB)

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…

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 compendium deals with the ecology and economic importance of the poplars, willows, hickories, birches, beeches, oaks, elms, nettles, sorrels, docks, and smartweeds growing in New York's Catskills. Provided are keys for identifying each plant to species by flowers, foliage, or winter buds. A line drawing accompanies a summary of basic data…

THIS BOOK WAS WRITTEN TO FUNCTION AS A STUDENT LABORATORY MANUAL OR AS TEACHER RESOURCE MATERIAL FOR DEVELOPING A LABORATORY-CENTERED COURSE IN PRACTICAL BIOLOGY FOR STUDENTS IN THE 13-16 AGE GROUP. IT WAS DESIGNED TO SUPPLY A COMPREHENSIVE SET OF EXPERIMENTS WHICH, WHEN CARRIED OUT IN CONJUNCTION WITH NORMAL THEORETICAL AND ANATOMICAL STUDIES,…

This teaching guide is one of a series developed by the Curriculum Research and Development Group at the University of Hawaii. The program is laboratory and field oriented for elementary students. The focus of study for the project is the plant and animal life and the physical components of the Hawaiian environment, and their ecological…

Description of a pilot study that replaced a geographic emphasis in sixth-grade biology with an ecological and evolutionary emphasis. (ND)

Exercises are presented for classification of marine algae on the basis of biochemical characteristics such as pigmentation, cell wall components, and food storage products. (BB)

This pilot study done with non-majors in a botany class indicate that: (1) Students with prescribed activities may achieve more cognitive knowledge during the course; (2) Students with a choice of activities may increase their long-term retention and enhance their affective areas of learning. (MA)

High school students learned to monitor air quality using lichens in a National Science Foundation sponsored program. In this article, monitoring procedures are discussed briefly along with means to adapt the exercise to your own area. (MA)
