Describes a laboratory experiment which focuses on the importance of water in germination and seedling emergence. Discusses the activity's design, expected results, and possible application. Offers suggestions for extending the experiment. (ML)

This manual provides learning activities for use in two vocational agriculture courses--ornamental horticulture I and agricultural technology I. These activities are intended as aids in the teaching of application of science principles. An introductory chart gives a summary of how vocational agriculture objectives match objectives of specific…

This set of 16 laboratory activities is designed to illustrate the life cycle of Brassicae plants from seeds in pots to pods in 40 days. At certain points along the production cycle of the central core of labs, there are related lateral labs to provide additional learning opportunities employing this family of plants, referred to as "fast…

Provides five secondary level investigations designed to examine allelopathy, the inhibition of plant growth by chemicals produced by another plant. (MA)

A simple, low-cost experimental system can be used to demonstrate the "in vivo" effects of barbituates on seed germination and seedling growth behavior in different plant species. Lipid solubility and concentration of individual barbituates both affect the response. List of materials needed, procedures used, and typical results obtained are…

Students conducted an experiment to study the plant growth of three Amaryllis plants. Students examined the speed and amount of growth, cross-pollinated the plants to produce seeds, and compared the growth of amaryllis seeds to the growth of onion seeds, a plant in the same family, Amaryllidaceae. (MDH)

Describes the experimental procedure and expected outcome in the growth of rice seedlings with light conditions and water aeration as variables. (GS)

Methods of investigating plant root growth developed for research purposes can be adopted for student use. Investigations of the effect of water table level and of ethylene concentration are described, and techniques of measuring root growth are explained. (Author/ML)

Suggests current scientific literature published in journals of biological research as a source of new, interesting, and enlightened experiments to reinforce an understanding of the process and sense of science. Presents an exercise developed using current literature. (EB)

Describes the life cycle of the Amaryllis plant from bulb to blossom. Suggests 12 activities in which students monitor plant growth, examine plant parts, make drawings of the plant, and eat flowers of other plants. (MDH)

Describes the method used at Macquarie University, Australia, for implementing the home experiment approach in first-year biology. The sequences of activities for experiments in plant growth are included; and assignment sheets are appended. (CS)

Activities and experiments with leaves are given for use with elementary students. Classifying and measuring are ideas which are suggested for involving children in some in-depth projects with leaves. (SA)

Recounts an anecdote about a teacher's science anxiety resulting from the mysterious results of a plant growth experiment. Students found that bean plants grew taller in a dark closet because of etiolation. Points out that teachers need to deal with experimental results objectively and resist looking for "right" answers. (MDH)

Provides a variety of science activities structured around the germination and growth of oak trees from acorns. (CP)
