Offers suggestions for activities that demonstrate the principles of osmosis. Explains how decalcified chicken eggs can be used to give students practice with measurement, experimental procedures, and science principles. (ML)

Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)

Suggests using squids for classroom investigations. Background information about these marine animals and a dissection activity are included. (JN)

Discusses the culturing of microorganisms as a laboratory activity emphaszing the growth of microorganisms in food. Provides background and safety information, procedures, and additional ideas.

Provides background information on honey ants. These ants are found in dry or desert regions of North America, Africa, and Australia. Also provides a list of activities using local species of ants. (JN)

This paper examines the effectiveness and feasibility of introducing relaxation and visualization techniques as study skills. Fifth grade science students from Charlottesville, Virginia (N=43) received six 20-minute classes using relaxation to study information on famous scientists. Results of this study indicate that relaxation and visualization…

This learning packet was developed for grade 5 to teach about the geology of a park. Sections include: (1) Introduction, which introduces the North Carolina State Park System, Hanging Rock State Park, the park's activity packet, and the geology of the park; (2) Summary, a brief summary of the activity outlines including major concepts and…

What happens in a classroom that fosters the Harvard Project Zero teaching for understanding framework? That is the initial inquiry for this pilot ethnographic study of African American fifth graders in an urban public school. The study sets out to show how children are engaged in a class set up to understand science and mathematics. Themes…

Presents a lesson plan for teaching abstract science concepts to gifted middle school students. The lesson integrates a physical education component into science instruction to reinforce the abstract notion that electrons emit energy in the form of visible light. (CR)

A teacher training program and classroom materials were developed to teach the science of alcohol to American Indian students in grades 4-9. The science of alcohol curriculum uses the holistic approach of the "new science paradigm" and includes cultural examples to make each unit relevant to Indian students. (SV)

Reports results of study examining the effect of inservice education program on middle school science teachers attitudes toward teaching and on teaching behaviors. A nonrandomized control group pretest/posttest design was used with a sample of 44 teachers. Results showed no significant attitude difference between the treatment groups. However,…

A procedure-based observational scoring system and a notebook completed by students were evaluated as science assessments for 41 fifth grade students experienced in hands-on science and 55 fifth grade students inexperienced in hands-on science. Results suggest that notebooks may be a reasonable, although less reliable, surrogate for observed…

Describes creating a Model Aquatic/Terrestrial Ecosystem for use in helping students understand how water moves beneath the ground's surface. The model is constructed from a fish tank using rocks, soil, gravel, clay, and organic materials. Author describes possible cooperative-learning and problem-solving activities that can be done with this…

Presents an activity to determine the identity of animals that owls ingest. Students dissect and examine the contents of "owl pellets" which are the indigestible parts of animals that are regurgitated after eating. Provides instructions for implementing and extending the activity. (MDH)

The relations of motivational variables to self-reported cheating behavior and beliefs in science were studied with 285 middle school students. Students who reported cheating in science perceived that their classrooms were extrinsically focused. The use of deep cognitive strategies was related negatively to cheating. (SLD)
