The development of a spaceflight simulation program as part of a research and development course is described. Topics such as space exploration, design, propulsion, aerodynamics of space craft, robotics, communication, construction, medicine, lasers, hydroponics, geology, chemistry, and space physiology are emphasized. (KR)

Presents a method for initiating discovery learning in early childhood classrooms through the study of ants. Children read about ants, record observations, and conduct experiments. This method teaches children to explore the environment, organize activities, seek resources, and engage in scientific inquiry. Examples of children's work are…

The idea that the methodologies provided by research should serve as models in developing practices in the classroom and in finding adequate solutions to students' and society's problems is discussed. The thoughtfulness of science, the scientific method, and science teaching are included. (KR)

A range of alternative approaches to student work in science is presented. The approaches are illustrated by examples of students' work including cartoons, cards, poems, and posters. A number of audiences other than the teacher is identified as a potential focus for students' written work. (KR)

An astrophysics course based on the constructivist approach to science teaching is described. The study of galactic structure is given as an example. Direct experiences and observations, representative-symbolic language, organized knowledge, and formal strategies are emphasized. (KR)

Ways of working in drama that can be readily utilized by science teachers are provided. The strategies of sociogram, teacher in role, role play, and trial scenes are described. Students' attitudes toward different teaching styles and the frequency with which teaching/learning strategies are used are presented. (KR)

An integrated lesson for kindergarten that familiarizes students with the phases and the surface of the moon is provided. Activities allow students to draw comparisons between the surface of the moon and the earth. Questions to ask students, directions for the activities, and a list of needed materials are included. (KR)

The abundance of life, the highly varied geologic formations, and climatic variations found in a wide range of deserts is presented. Misconceptions held about the desert are discussed. A list of resources and activities are included. (KR)

Described are ways in which children with the help of their parents and community can get involved with recycling, energy conservation, composting, and picking up litter. Environmental student projects on water conservation, planting trees, and Earth Day pledges are included. (KR)

A technique for the numerical identification of bacteria using normalized likelihoods calculated from a probabilistic database is described, and the principles of the technique are explained. The listing of the computer program is included. Specimen results from the program, and examples of how they should be interpreted, are given. (KR)

Presented are activities in which students can observe dragonflies in their natural environment, capture them for examination, or make dragonfly models. Background information, directions for a field observation activity and making the models, and benefits of dragonfly study are included. (KR)

This article takes a critical look at practical work in school science and the often extravagant claims that are made for it. A case is made for a more rigorous, theory-driven approach to practical methods. (Author/CW)

Discussed are teaching methods that can be used in association with amusement park rides. The basic principles behind the effects of several rides are reviewed and illustrated. (CW)

A simple experimental arrangement that makes it possible to simultaneously observe and compare on a screen the two interference patterns produced by reflected and transmitted light from incident white light impinging on a soap film directly is described. Procedures and illustrated effects are discussed. (CW)

Two experiments which can be used to illustrate light diffraction using compact disks are detailed. Included are procedures, computations, and probable results. (CW)
