Discussion of the botany lessons used at two schools points out the need for fifth and sixth grade students to be taught the principles of plant life through observations made at an experimental garden plot at the school. (ND)

Describes a science activity in which any and all elementary school students can become involved and enjoy success. Various activities centered around a student-devised mini-garden are proposed. (EB)

Explains how Zebrina pendula can provide an excellent material for demonstrating a variety of cellular features in plants by using a dissecting microscope. (GA)

The Japanese morning glory, a short-day plant, is an excellent specimen for studying photoperiodism. This article gives ideas for investigations including the effects of hormones, light quality, and temperature. Preparation of the seed is also discussed. (BB)

Methods are described for an initial survey of trampling pressure and soil compaction, and their effects on both the soil environment and the plant community structure. (Author/BB)

Manipulative models are compared to static models as effective adjuncts in learning to identify plant organs and tissues. Results offer statistical evidence that students have more success at learning to recall the names and functions of plant tissues and microscopically identify them if hands-on experiences have been provided. (Author/MA)

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

Callus induction from species of Haworthia can be done quickly in the laboratory with minimal equipment to study tissue dedifferentiation and cellular redifferentiation. It is shown that the cultured cell can also be used to study and evaluate the effects of various mutagens, carcinogens, and pesticides in controlled environments. (Author/MA)

The current popularity of house plants can provide the basis for numerous classroom activities. Students can make flower pots from tubs and cans, chart plant growth on a graph, make mint sherbert, or expand their vocabulary by learning plant descriptors. Details and more suggestions are included in this article. (MA)

Presents contributed laboratory techniques and demonstrations aids. (CP)

Describes the diversity of plants. Outlines novel developmental and complex genetic processes that are specific to plants. Identifies approaches that can be used to solve problems in plant biology. Cites the advantages of using higher plants for experimental systems. (RT)

Provides background information on poison ivy and offers suggestions for instructional activities. Includes illustrations of the varieties of poison ivy leaf forms and poison ivy look-alikes. Highlights interesting facts and cases associated with poison ivy and its relatives. (ML)

Presents an account of the making of a wildlife garden. Reviews the problems and outlines the plans and methods that succeeded in the project. Includes 21 illustrations of vegetation as well as descriptions of pond, marsh, meadow, and woodland areas. (ML)

Three innovative ideas for college instruction include a freshman assignment to write recruitment letters to high school students with similar interests, introductory art history classes taught solely in a museum adjacent to the campus, and use of the "Hunt of the Unicorn" tapestry to combine plant identification practice with art…

Describes the analysis of dandelion peduncle growth based on peduncle length, epidermal cell dimensions, and fresh/dry mass. Methods are simple and require no special apparatus or materials. Suggests that limited practical work in this area may contribute to students' lack of knowledge on plant growth. (Author/DH)
