A technique to measure the potency of leaf compounds against herbivores with the use of a bioassay is described. Bioassays are useful in classes where students have career plans like medicine in which bioassays can be used as tools for screening plants for possible medicinal potency.

There are a number of ways to capture student interest and improve student ability to understand complex phenomena. Without attempting any systematic assessment of the improvement in student learning the analogies, conversations with students lead to believe that techniques are a valuable tool in the botanist's toolbox.

Today's biology educators face the challenge of training their students in modern molecular biology techniques including genomics and bioinformatics. The Dolan DNA Learning Center (DNALC) of Cold Spring Harbor Laboratory has developed and disseminated a bench- and computer-based plant genomics curriculum for biology faculty. In 2007, a five-day…

At home, children often have pets that they take care of and play with; even in the classroom it is not uncommon to find a wormery, an aquarium or an ant farm. However, children rarely have the opportunity to own and care for a plant over a lengthy period of time, let alone a tree. The authors describe a project in Portugal aimed at improving…

This book provides laboratory experiments to enhance any food science/botany curriculum. Chapter 1, "Introduction," presents a survey of the techniques used in plant biotechnology laboratory procedures. Chapter 2, "Micronutrition," discusses media and nutritional requirements for tissue culture studies. Chapter 3, "Sterile Seeds," focuses on the…

This book is a collection of life science classroom demonstrations. Explanations that review key concepts are included. Topics are: stimulus and response; gravitropism; phototropism; living organisms; carbon dioxide; gases emitted by plants; greenhouse effect; stomata; transpiration; leaf skeletons; seed growth; water evaporation in plants; carbon…

This manual describes 14 hands-on exercises for middle school introductory biology courses that are designed to allow all students to be involved in self-discoveries about life and plant life in particular. The exercises were developed to supplement normal classroom activities by allowing students to initiate ongoing projects to investigate the…

Ethnobotany is the study of the relationships between plants and people. Ethnobotanists study a large range of interests related to indigenous populations, including the use of plants for foodstuffs, medicines, dyes, transportation, clothing, shelter, and ritual. The Navajo, like other indigenous groups, have developed a wealth of knowledge about…

The National Science Education Standards (NSES) provides few resources for teaching about plants. To assure students understand and appreciate plants, the author advocates teaching about plants as a basic biological concept, avoiding animal chauvinism in biology coursework, correcting pseudoscience and anthropomorphisms about plants, and making…

Describes two investigative labs that use live plants to illustrate important biological principles, include quantitative analysis, and require very little equipment. Each lab is adaptable to a variety of class sizes, course contents, and student backgrounds. Topics include the evolution of flower size in Mimulus and pollination of Brassicas. (DDR)

Presents material for a talk and demonstration about the relationship of potato types to their different uses by consumers and processors. Includes background information for the instructor and discussions to accompany classroom exercises. Discusses the history of the potato, potato types and external characteristics, and internal characteristics…

Describes a year-long course called Outdoor Science taught at an American Indian reservation high school that demonstrates to students the connection between traditional tribal knowledge and western science to spark student interest in science. Presents a list that contains references on the subject of ethnobotany. Includes specific references for…

Presents an interview protocol used to identify and evaluate students' conceptions of plants which is an invitation to participate in the third national study exploring elementary students' science conceptions. (YDS)

Describes a business-school partnership involving gifted students in the design and cultivation of a medicinal garden. Students studied the uses of native plants for medicine, food, shelter, clothing, and landscaping, and developed portfolios and presentations through their work on the community garden site and an outdoor classroom. (PB)

Discusses the use of biographies to increase student interest in plant science. Presents the biography of Wangari Maathai, a Kenyan woman who empowered women and children to plant and care for millions of trees in Kenya, as an example of teaching with biographies. (JRH)
