Presents techniques used for disinfestation of plant material, preparation of equipment and media, and laboratory procedures for tissue culture using cauliflower. Details methods for preparing solutions and plant propagation by cloning. (CW)

Describes how lectures, laboratories, and role playing can be used to introduce students to the importance of water quality of water used for plant growth. (PR)

This unit, developed by the Third World Science Project, is designed to add a multicultural element to existing science syllabi (for students aged 11-16) in the United Kingdom. The project seeks to develop an appreciation of the: boundless fascination of the natural world; knowledge, skills, and expertise possessed by men/women everywhere;…

Suggests an approach and methodology for analyzing field and laboratory populations. Describes an experiment using mustard to show how competition and inequality can be assessed. Discusses the variables responsible for determining the abundance of organisms. (CW)

Describes laboratory procedures, demonstrations, and classroom activities/materials, including rapid peat-depth surveying; leaf-flotation method for measuring photosynthesis, an educational game demonstrating basis of protein synthesis, daffodil phototropism; chromatography apparatus; egg white digestion, and chromatography apparatus. Also…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including chi-square tests on a microcomputer, an integrated biology game, microscope slides of leaf stomata, culturing soil nematodes, technique for watering locust egg-laying tubes, hazards of biological chemicals (such as benzene, benzidene, calchicine,…

Discusses traditional school demonstrations and experiments in hydrotropism. Explains that these experiments seem to "prove" hydrotropism, but yet most botanists reject hydrotropism. Teachers continue to teach the concept because it is logical and the experiments are simple. (PR)

This article describes the use of the "glabrous1 (g11)" mutant and constitutively active "(CA)-rop2" transgenic plants of "Arabidopsis thaliana" in teaching genetics laboratory for both high school and undergraduate students. The experiments provide students with F[subscript 1] and F[subscript 2] generations within a semester for genetic and…

This book helps teachers fulfill curriculum requirements by building both science content and process skills through hands-on exploration. Ten broad subject areas are covered: (1) Discovering Science, (2) Matter and Energy, (3) Humans, (4) The Environment, (5) Rocks, (6) Plants, (7) Living Creatures, (8) Weather, (9) The Heavens, and (10) Applying…

Based on the idea that active participation stimulates the processes by which learning takes place, this document provides teachers and students with a variety of information and learning activities that deal with plants and animals in nature. Basic concepts are presented through the use of laboratory experiments, worksheet exercises, diagrams,…

This document contains a set of instructional materials about photosynthesis that were used in a research study of middle school science teaching during 1985-86. The Middle School Science Project investigated ways to help middle school science teachers use teaching strategies that were identified in earlier studies as particularly effective in…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including water relation exercise on auxin-treated artichoke tuber tissue; aerobic respiration in yeast; an improved potometer; use of mobiles in biological classification, and experiments on powdery mildews and banana polyphenol oxidase. Includes reading lists…

Discussed are the advantages and processes of making collections with children. An activity for making a classroom collection (herbarium folios) is described and includes materials and procedures. The processes of collecting and classifying are stressed. (CW)

The Medicinal Plants of the Southwest summer workshop is an inquiry-based learning approach to increase interest and skills in biomedical research. Working in teams, Hispanic and Native American students discover the chemical and biological basis for the medicinal activity of regional plants used by healers. (Contains 4 tables and 1 figure.)

This life science activity module was designed to facilitate student conceptualization of plant growth. It is intended for use primarily in elementary grades but may be useful at higher grades. It provides students with hands-on experience and observational skill development. The package provides: (1) a teacher background sheet; (2) an activity…
