Discusses the importance of studying nectar biology. Describes how to extract nectar from various flowers, measure nectar volume, determine sugar concentration, and determine caloric value per nectar sample. These data are then related to hummingbird energetics to determine how many flowers are required to supply the pollinator with its caloric…

There is a widespread belief among the public and even among chemist that plants do not contain cholesterol. This wrong belief is the result of the fact that plants generally contain only small quantities of cholesterol and that analytical methods for the detection of cholesterol in this range were not developed until recently.

One of the author's pet projects is to demonstrate to teachers how easy it is to grow plants in the classroom. In order to create equitable schools in Ontario, teachers are mandated to honour diversity in their classrooms by celebrating a diversity of special significant days such as Ramadan, Kwansaa, Diwali and Chinese New Year. Not only does…

This article presents a field technique that exposes students to the indirect effects of habitat fragmentation on plant distributions through studying edge effects. This assignment, suited for students in an introductory biogeography or resource geography class, increases students' knowledge of basic biogeographic concepts such as environmental…

Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

This study examines the impact of "Disaggregate Instruction" on students' science learning. "Disaggregate Instruction" is the idea that science teaching and learning can be separated into conceptual and discursive components. Using randomly assigned experimental and control groups, 49 fifth-grade students received web-based…

It is well documented that people are less interested in studying plants than animals. We tested whether university students would selectively recall more animal images than plant images even when equally-nameable plant and animal images were presented for equal lengths of time. Animal and plant images were pre-tested and 14 animal-plant pairs…

The "Under the Mistletoe" project was developed to capitalize on student curiosity about the American Christmas Mistletoe plant and draw learners into an engaging, inquiry-based exercise that incorporates numerous life science standards and collaborative research. By collecting data on host and nonhost tree size, location, and number of mistletoe…

In the project presented in this article, high school students create and observe miniecosystems in an ecology unit designed around a 5E (engagement, exploration, explanation, elaboration, and evaluation) instructional model. Students choose a wide variety of organisms and use creativity to design miniecosystems. (Contains 1 table and 3 figures.)

Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…

Plants can survive in even the harshest of environments, from the freezing Arctic to the arid desert. In All About Plant Adaptation, join young plant lovers as they uncover some of the amazing ways that plants have adapted over millions of years enabling them to survive almost anywhere on Earth. Discover how some plants living in cold, arctic…

A demonstration that can be used to illustrate diffusion and osmosis is presented. Discussed are materials, procedures, and an explanation for the effect. (CW)

The construction and stocking of an in-class pond is discussed. Suggestions for eight activities using the pond are provided. A list of 15 references is included. (CW)

Enables students to examine the time course for seed imbibition and the pressure generated by imbibing seeds. Provides background information, detailed procedures, and ideas for further investigation. (DDR)
