Applying botanical knowledge to a simulated forensic investigation provides inquiry-based and problem-based learning in the botany classroom. This paper details one such forensic investigation in which students use what they have learned about plant morphology and anatomy to analyze evidence and solve a murder mystery. (Contains 1 table.)

Presents an exercise that demonstrates how plants cope with multiple resource limitations in the field. Stimulates students to think about interactions among multiple limited resources and the challenges plants as immobile organisms face when characteristics that increase the capture of one resource negatively impact the availability of another.…

When students think of evolution, they often think of those genetic changes that occur to make organisms different. This article describes how students can become better informed of convergent evolution, the process by which organisms with dissimilar ancestors come to resemble each other. (ZWH)

The differences between measuring light intensity for the human eye and for plant photosynthesis are discussed. Conversion factors needed to convert various units of light are provided. Photosynthetic efficiency and the electricity costs for plants to undergo photosynthesis using interior lighting are described. (KR)

Discusses the succession of ecological and geological structures as exhibited at Glacier National Park, Montana. Topics discussed include glaciers, the geological history of Glacier National Park, glaciation of the Rocky Mountains, paleoecology, the vegetational history of the Northwestern United States, and glaciation and the modern vegetation.…

Uses diagrams to aid in describing a simple, rapid technique for staining the nuclei of pollen grains that have been germinated in vitro. (ZWH)

Photography makes an easy and excellent tool for teaching field biology courses, allowing students to study nature without harming it. This photographic technique is used in capturing images of vertebrates, invertebrates, and plants during class field trips, then making these images available for students to identify and study from a departmental…

Presents an experiment that provides students with an opportunity to investigate folk medicine and herbal cures and their accompanying claims. Involves isolating some active compounds from plant materials and demonstrating their antibacterial activity. (JRH)

Describes the diversity of flowers with regard to the flower paintings of Pierre-Joseph Redoute, books about flowers, and research in genetic studies. Discusses gardening flowers and flowering strategies and criticizes the fact that biology education has moved steadily away from plants. (KHR)

Describes an alternative to studying plant community composition and dynamics. Suggests that teachers and students collect soil samples containing buried seeds (the seed bank), germinate the seeds in the laboratory, and analyze community dynamics through the composition of the seed bank. (ZWH)

Describes an education-government-community environmental partnership program that set aside permanent environmental study sites where students and teachers can conduct meaningful, service-oriented environmental research. Highlights a project where students prepared a comprehensive plant species inventory of a section of the wilderness area.…

Presents a tobacco haploid experiment in which students learn the cytogenetic technique of metaphase analysis of chromosomes and experience the basic principles of haploidy, diploidy, and polyploidy. (YDS)

Author provides details about Helmont's experiment that was a milestone in the history of plant biology since it marked the start of experimental plant physiology. Concludes that Jean Baptista van Helmont's supposedly simple experiment becomes complex when trying to determine the methods he used, evaluate his sources of experimental error, and…

Presents an embryology laboratory observing the development of Ginkgo biloba's embryos into trees. Explains the methodology for the lab and discusses research questions. (YDS)

A modification of the popular C-Fern system, the tropical fern Ceratopteris richardii is developed in which students plate out a genetically mixed set of fern spores and then select for specific mutants. This exercise can provide students with an experience in plant mutant selection and can be used as a platform to expose students to a diverse…
