Explains how the tobacco mosaic virus can be used to study virology. Presents facts about the virus, procedures to handle the virus in the laboratory, and four laboratory exercises involving the viruses' survival under inactivating conditions, dilution end point, filterability, and microscopy. (MDH)

Describes an experimental system that allows students to observe pollen tubes in vitro and to investigate a variety of aspects of pollen tube-style interactions. One interaction provides an example of postmating reproductive isolation. (MDH)

The grade 6-7 class at St. Patrick's School in Hamilton (Ontario) engages in outdoor environmental projects to enhance classroom learning. Some student activities have been (1) worm composting; (2) tree planting; (3) restoring tern nesting areas; and (4) planning and cultivating a sophisticated garden on school grounds. (KS)

The extinction of farm animals and crops is rarely brought up during discussions of endangered species and biodiversity; however, the loss of diversity in crops and livestock threatens the sustainability of agriculture. Presents three activities: (1) "The Colors of Diversity"; (2) "Biodiversity among Animals"; and (3) "Heirloom Plants." Discusses…

Argues that treatment of one investigative longitudinal topic from start to finish in a high school biology class can illustrate many major ideas and concepts. Discusses ways to use various longitudinal studies of plant growth with General Biology classes. (WRM)

Explains the process of creating a curriculum based on the National Science Education Standards (NSES). Introduces an activity where students experience flowers and their environments. Focuses on Content Standard C of the NSES. (YDS)

Describes a series of four lessons that integrate social studies, language arts, and life science for high school students. Explains that students participate in a wildflower collection activity, interview a person from another culture to collect interesting facts and wild stories, research a flowering plant, and make wildflower bookmarks. (CMK)

Describes a series of low-cost experiments to investigate the ability of seeds from different species to acquire tolerance of thermal stress. Suggests links to discussions on molecular biology, physiology, ecology, and evolution. (WRM)

This article describes a collaborative effort that included a botany professor, an art teacher, and a science teacher, called,"Plants, Pots, and Paints." This interdisciplinary project was successful in connecting content across disciplines (science to art) and for motivating fourth-and fifth-grade students to create something beautiful both they…

The authors applied constructivist learning theory to environmental education to explore knowledge gains, student attitudes, and engagement among high school students exposed to a week-long unit on nonnative plant species. The authors compared constructivist and traditional teaching methods. Each class was given a pretest and a posttest. The…

A generic teaching format in which students actively participate in a whole-class collaborative-learning experience is described. The entire class, divided into groups, made a joint effort to overcome a hypothetical outbreak of a new plant disease. High scores on an examination question concerning the project indicated successful assimilation of…

This curriculum was written for youth organizations and secondary students in the County of Sacramento, California to develop their ability to: (1) recognize and evaluate how decisions are made about land use; (2) understand the roles of elected officials, property owners, citizens, and local governmental departments and agencies; (3) understand…

This volume of 16 chapters by 15 contributing authors was conceived as a means of drawing together a body of basic information about the Great Lakes that is up to date, based on sound research, and interpreted by experts in the scientific, historical, environmental and political value of the Great Lakes to North America and the world. Chapters…

School students, and their teachers, seldom have opportunities to investigate something in nature. Yet children's development, as perceived by Piaget, and historical scientists' learning, involves investigation. We acted to include these investigative responses and historic resources into our work with new science teachers. We did this in the…

This book is a compilation of biology labs that are safe, simple, dependable, economical, and diverse. Some of the 25 investigations contained within this book involve organisms that are free for the taking and returned to the environment unharmed following the investigations. Students gain experience in making observations, forming hypotheses,…
