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.

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)

Materials and methods for studying the functioning and responses of stomatal guard cells are described. (PB)

Discusses methods for determining the population size of pond phytoplankton, including water sampling techniques, laboratory analysis of samples, and additional studies worthy of investigation in class or as individual projects. (CS)
