These materials were developed to meet an expressed need for bilingual materials for a secondary school Life Science Course. Eight units were prepared. These include the following topics: (1) Introduction to the Scientific Method; (2) The Microscope; (3) The Cell; (4) Single-celled Protists, Plants, and Animals; (5) Multicellular Living Things;…

Presented is a biological game utilized to teach fungi life cycles to secondary biology students. The game is designed to overcome difficulties of correlating schematic drawings with images seen through the microscope, correlating life cycles of fungi and host, and understanding cyclic development of fungi. (SL)

Presented is an activity that uses ground ivy to display different growth forms under different light intensities. Specimen preparation, materials, procedures, and probable results are discussed. Examples of graphs of the data are provided. (CW)

Describes activity relating to the study of trees. (SL)

Discusses the use of native Australian plants in 8th and 9th grade Biology classes. (SL)

Reported is a technique for chromosome staining that is simple, rapid, inexpensive, and requires little skill for success. (PB)

Appropriate for secondary school botany instruction, this study guide focuses on the important roles of plants in human lives. Following a rationale for learning the basic skills of a botanist, separate sections discuss the process sunlight undergoes during photosynthesis, the flow of energy in the food chain, alternative plant lifestyles, plant…

An activity that can be used to teach plant nutrition and the use of hydroponics is presented. Materials and procedures are discussed. Possible topics for science projects are suggested. (CW)

Plant material can be used for classroom investigations of factors influencing infection. Plant responses to infection can be used as teaching models for animal as well as plant diseases. Three activities are discussed. (Author/CW)

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

Described are the techniques and results of using this tissue culture activity. Discusses the advantages of using such techniques in teaching alternation of generation life cycles to biology students. (CW)

This guide was developed for use by individuals with little or no botanical training who wish to identify native ferns of New York, New England, New Jersey, and Pennsylvania. A random access key, developed by the author, provides multiple pathways for identification of 60 species in 29 genera of ferns. (CS)

Discusses between-species variation in adaptation of the photosynthetic mechanism to cope with wide fluctuations of environmental water regime. Describes models for water conservation in plants and the role of photorespiration in the evolution of the different pathways. (CW)

Polk County's environmental education program was integrated into the existing curriculum, K-12, by employing an interdisciplinary approach coordinating the various disciplines. Emphasis is placed on the following phases of environmental education at the designated grade levels: (1) primary - awareness, (2) intermediate - concern and information,…
