The Science Curriculum Improvement Study has developed this teacher's guide to "Populations," the third part of a six-unit life science curriculum sequence. The six basic units, emphasizing organism-environment interactions, are organisms, life cycles, populations, environments, communities, and ecosystems; and they make use of…

Describes a procedure for growing plants from seeds. (SL)

Discusses procedures for growing plants under various artificial lights: incandescent globes, flourescent tubes, and plant growth tubes. (SL)

Described is a biology curriculum being developed in West Germany, which utilizes units of 10 to 15 lessons that may be placed in different positions within the overall curriculum. Ten units have been published for grades 5 through 8. Units for grade 3 to 13 are in development. (SL)

Described are science activities for monitoring bird migrations. (SL)

Describes current attempts to legislate a requirement for schools to teach creation and evolution in South Carolina. Implications for this movement for the entire nation are discussed. (SL)

This curriculum guide for students in grades K-4 is part of the My Health My World series which explores environmental health issues. Focusing on water, it includes (1) an activities guide for teachers which focuses on physical science, biology, and environment and health, presenting activity based lessons that entice students to discover concepts…

Parent Teacher Associations can be persuaded to support programs in schools. Article describes one such attempt which resulted in setting up bee hives and large aquaria in an elementary school. (PS)

Differences between games, simulations, and case studies are identified. The values of these approaches are considered and examples of particular uses within a biological context are discussed. Lists of commercially available materials and articles on biological games are provided in appendices. (Author/JN)

Rationale for and example of a strategy to overcome reading difficulties are described. Before reading a bio-technical text, students read a story (sample included) in which the same biological and technical terms are used, but in a more familiar context and style. (Author/JN)

Highlights activities of the National Science Teachers' Search for Excellence in Science Education (SESE) program. The program involves searching for exemplary programs which can become models for designing new programs. A list of six SESE exemplars chosen for onsite study is provided. (JN)

Briefly described are 25 "hands on" classroom activities which require live, freshly killed, or preserved grasshoppers. Topics of activities include predator-prey relationships, feeding habits, locomotion, dissection, anatomy, and population estimates. (DS)

Described are the advantages of using crayfish in an elementary or secondary biology class, crayfish activities, field collection, classroom care, and identification. (DC)

Described is an activity where students determine the effect of different toothpastes on teeth. Students used observational data and pH changes to determine any changes in the teeth. Included are a list of materials, procedures, and results. (KR)

Presented is an activity that investigates the effect of sugar on teeth using cola, sugar solution, and water. Included are the materials, procedures, resources, and alternative lessons. (KR)
