When asked about protein, students often mention meat, protein bars, and protein's role in building muscles. Many students are not aware of the most basic function of protein: linking genes and traits. Because of its importance in molecular genetics, protein function is included in the life sciences section of the "Next Generation Science…

The Habitat Project is a multiday, differentiated, interdisciplinary environmental science lesson that incorporates skill-building and motivational strategies to internalize ecosystem vocabulary. Middle school students research an animal, display its physical characteristics on a poster, build a three-dimensional habitat and present their work…

Presents activities that use antifreeze to introduce students to concepts such as density, specific gravity, solutions, and freezing and boiling points. (JRH)

This guide, in English and Spanish, is designed to provide teachers with a scientific basis for identifying myths and distortions about men and women. A pre-test and post-test are included to measure the user's awareness of stereotypes. Object lessons address the following areas: (1) common sexual stereotypes; (2) sexual functions; (3) the…

Chickens, instead of rats, were used in an upper-level laboratory course on animal learning. To help other instructors interested in using chickens for a lab course, a discussion of the physical and behavioral characteristics of chickens is provided. Student reaction to the course is also discussed. (RM)

Presents lesson plan to be used after introductory lessons on realizing similarities and differences in people. Plan was designed after request from teacher to help deal with children who were putting down others because their physical characteristics were "different." Lesson demonstrates to children that being different is desirable and that…

Chemical demonstrations can and do enhance an otherwise potentially dull subjects--the properties of hazardous materials. This book contains the recipes for presenting several chemical demonstrations. Demonstrations are designed to be relatively easy to perform and present minimal hazards if done properly. The book contains an introduction, safety…

Swimming teachers and coaches can improve their feedback to swimmers, when correcting or refining swim movements, by applying some basic biomechanical concepts relevant to swimming.

The unit on an aging program described is designed to provide students with an accurate knowledge base of the biological, psychological, and sociological aspects of aging as well as with experiences to sensitize them to the realities of aging. (JMF)

Presents a complete set of laboratory experiences on density. Includes establishing a density table, identifying an unknown, determining the density of irregular solids, and expanding the density table. Activities can be augmented with discussions about other applications. (DDR)

Special problems of adult language learners aged 50 and older studying English as a second language include physical, social, and psychological factors. Physical factors related to aging include vision and hearing problems that adults may not be willing to admit to. Older adults may also be more sensitive to room temperature and lighting, and may…

Learning activities for health education are outlined for students from the primary level through the secondary grades. The uniting theme of the curriculum is the relationship of physical health to other health factors. A statement of the course or unit goal precedes each suggested activity, followed by the specific content of the unit and related…

Presents an activity that can be an effective way to teach the key concepts of density, specific gravity, miscibility, and immiscibility without expensive reagents or equipment. Includes pre-laboratory discussion tips and student laboratory worksheets. (DDR)
