Describes a cooperative science program between an elementary and a secondary school in which high school students introduce topics and present demonstrations in biology to students in the elementary school. (JR)

Describes the polywater exhibit at the Worcester Science Center in Massachusetts. Curiosity and interest are stimulated in young people by allowing them to handle the materials in the exhibit and by providing them with instructions for making polywater. (JR)

Discusses the procedures that should be observed in constructing a dichotomous key. The keying exercise described was used as a laboratory activity in a biology course for elementary education majors, however it could be used in other courses. (JR)

A multimedia approach to science teaching is based on sound psychological principles. Every aspect of such programs must be carefully planned and integrated. Criteria for evaluating suitability of multimedia learning resources are suggested. (PS)

Describes techniques using everyday examples and analogies which aid students in distinguishing between two terms with opposite meanings, such as anticline and syncline. (PS)

Commercial advertisements in publications can suggest numerous topics for student investigations. Students can gain research experience by devising experiments for testing products. (PS)

A small pond in a schoolyard provided year-round biological activities for children. As seasons changed, concepts and life relations also changed. Besides microscopic organisms in water, children learned about microscopic algae, detritus, and food chains. Concepts of predator-prey relationships and of ecosystems were successfully developed. (PS)

Small samples of students were chosen from two extreme types of schools (affluent-suburb and inner-city) to investigate the problem of presenting exercises in a manner students understand. The results raise questions about teaching procedures and the National Assessment evaluation. (DF) Aspect of National Assessment (NAEP) dealt with in this…

It can be helpful in learning science if the teacher places some emphasis on reading and comprehending language correctly. Described are few points of language which children find difficulty in understanding. (PS)
