Nonsense botany, an easy, amusing way of learning the principle of nomenclature, involves using English words (in Latin constructions) to describe a make-believe plant; a drawing of the plant accompanies the pseudoscientific name. Suggests that students use this technique (developed by the nineteenth century British humorist Edward Lear) when…

A hair dryer, plastic funnel, and microscope slide can be used for predicting pollen counts on a day-to-day basis. Materials, methods for assembly, collection technique, meteorological influences, and daily patterns are discussed. Data collected using the apparatus suggest that airborne grass products other than pollen also affect hay fever…

Explains the procedures used in a general botany course to obtain polarization, fluorescence, and dark field images using a standard student microscope. Provides sources for materials and references. (JM)

Methods of collecting, isolating, and culturing microscopic and macroscopic marine algae are described. Three different culture media list of chemicals needed and procedures for preparing Erdschreiber's and Provasoli's E. S. media. (BC)

Presents three activities: (1) investigating succession in a schoolground; (2) investigating oak galls; and (3) making sun prints (photographs made without camera or darkroom). Each activity includes a list of materials needed and procedures used. (JN)

Discusses the diversity and dynamic nature of the chemical components of postharvest crops. Also discusses the role of respiration and genetic control in chemical transformations leading to desirable and undesirable changes in the quality of edible plants after harvest. The role of enzymes in producing these changes is considered. (JN)

Describes: basic features of pollen grains (shapes, apertures, layering of wall, exine sculpturing); strategies for pollination (anemophily--wind transported, zoophily--animal transported); and the structures specialized for each process. Gives instructions for using scanning electron microscope photographs and for collecting, identifying, and…

"Access Nature" is an outdoor science curriculum that focuses on habitats. This curriculum targets students ages 6-14 and aims to develop environmental awareness, environmental leadership skills, and outdoor knowledge and skills. Specific adaptations for disabled students are also considered. Contents include: (1) "Introduction to…

This document features gardening activities for children in grades 3-5. Lesson plans target teaching children healthy eating habits; children should consume five servings of fruits and vegetables each day to take in the necessary vitamins and minerals essential for health and growth. Many lesson plans are also associated with physical activities…

This handbook was written in response to an identified need for more public information on Ontario's old growth forests. It is meant to be taken into old growth stands, where the learner can see, touch, and study the natural ingredients of old growth forests. Much of the handbook is a guide to forest history, helping the learner to discover…

This book is one of four books in the Science-by-Design Series created by TERC and funded by the National Science Foundation (NSF). This series presents directed instruction on how to successfully formulate and carry out product design. Students learn and apply concepts in science and technology to design and build a pair of insulated gloves, a…

Describes the method used at Macquarie University, Australia, for implementing the home experiment approach in first-year biology. The sequences of activities for experiments in plant growth are included; and assignment sheets are appended. (CS)

Describes a rapid staining technique for investigating the anatomical expression of two recessive genes. The demonstration is intended to stimulate students who are interested in the practical applications of genetics. (Author/SA)

Provides background information and teaching suggestions for collecting and using lichens in the classroom and for conducting field investigations. Focuses on structure, reproduction, photosynthesis, and effects of air pollution. (DC)
