Advocates that some established botanists should become involved in social and political problems to which botanical expertise is relevant. Discusses food production in relation to world population growth, indicating problems on which botanical knowledge and research should be brought to bear. Discusses herbicides and plant growth regulators as…

Several simple experiments illustrating how the light regime affects the final form of dog's mercury (Mercurialis perennis) are provided. These experiments, which can also be done with other plants, focus on differences in the anatomy, morphology, and physiology of sun and shade leaves. (JN)

Highlights major activities, conferences, conference and published papers, monographs, and research studies in paleobotany during 1982. Indicates that paleobotanists made more frequent use of the perspectives and ideas of disciplines as developmental biology and sedimentology in their research endeavors. (Author/JN)

Presents an expanded classification of the plant kingdom, emphasizing major evolutionary steps and differences in levels of complexity. Describes subdivisions and suggests that this classification, reflecting unity and diversity, may be logical, understandable, and useful to students. (JN)

Some of the problems encountered in devising sixth-form projects are discussed and a detailed account given of one project in which a study was made of the effect of onion bulb volatiles on the germination of lettuce seed. (Author)

The effectiveness of a modular approach to learning in a botany unit as compared to the traditional teaching approach in terms of learning efficiency, learning time, and mastery level is reported. Three references are cited. (Author/CHC)

Suggests six reasons why plants should be grown in science classrooms and gives instructions for constructing miniterrariums from plastic, two-liter, nonreturnable soft-drink bottles. (SK)

Discusses several of the plant responses to the environment and ways that these responses can be demonstrated. Includes phytochrome-controlled growth, phototropism, and geotropism. (CS)

A volunteer for an Earthwatch research project describes experiences in Nepal. (JD)

Lists and describes science museums in Europe. Countries include France, Switzerland, Italy, Germany, Denmark, Holland, England. (CS)

Describes an activity used at the Washington Park Arboretum that helps students understand cloning through plant propagation. Students also learn how to make a pot from recycled newspapers and how to make soil that is appropriate for the plants. (DDR)

Presents a laboratory activity to teach medical biology to undergraduate nonmajor business students. Uses herbalism as the theme concept to integrate subjects, such as anatomy, physiology, medical theory, and terminology. Includes topics, such as herb collection, medicine preparation, and herb storage. (SOE)

Focuses on a yearlong project designed to strengthen teachers' and students' understanding of plants, equip teachers with inquiry-based teaching techniques, and create a community of learners. (DDR)

Describes the Kids In Nature (KIN) program which is a partnership between Sedgwick Reserve and the University of California-Santa Barbara's Museum of Systematics and Ecology (MSE). Involves low-performing high school and feeder elementary school students in the restoration of their own land with plants and animals. (Contains 12 references.) (YDS)

Presents an activity that helps students explore how energy moves through an ecosystem. Students become plants and animals that thrive in a place near the school. In these roles they are allowed to experience the energy cycle. Materials for this activity are simple and easy to acquire. (DDR)
