Technology can support hands-on science as elementary students use computers to formulate field guides to nature surrounding their school. Students examine other field guides; open databases for recording information; collect, draw, and identify plants, insects, and animals; enter data into the database; then generate a computerized field guide.…

Describes the ways in which primary grade science teachers can use hands-on scientific activities to answer children's questions about science. In such activities, children discover and experiment with materials and objects to understand scientific ideas and processes. Suggests that teachers should encourage children's curiosity. (BB)

Provides a lesson plan with student worksheet for teaching the concept of geologic time to middle school students. The lesson is cited as representative of an Earth systems approach to science curriculum with emphasis on the age of the earth and the fact that its subsystems are constantly evolving. (MCO)

Several ways of exploring the subject of global warming within the context of a conventional physics syllabus are suggested. The physics underlying greenhouse phenomena, the process of modelling (especially computers), possible future climatic scenarios, and the differing nature of the uncertainties associated with the many fields of study that…

The importance of integrating the science curriculum from elementary through secondary classrooms is discussed. An example using the topic of the sea is used to explain the difference between true integration and correlation in both elementary and secondary levels. The importance of choosing learning activities that support objectives stated in…

A lesson plan for soil study utilizes the Tullgren extraction method to illustrate biological concepts. It includes background information, equipment, collection techniques, activities, and references for identification guides about soil fauna. (MCO)

Describes how Butner Elementary School at Fort Bragg, North Carolina, transformed a courtyard into a nature learning center, complete with three-tiered pond, fish, animals, and plants. The project, funded through the collection of aluminum cans, is used for science, archaeology, language arts, and social studies activities. The high level of…

Attitudes and policy developments in the United States on use of animals in education are reviewed, and the legislative position outlined. The influence of science competitions and national teacher associations on practice is discussed. The common invasive experimentation on sentient animals by young and inexperienced students is provoking…

Activities from the book "Connecting with Nature" are presented. Topics include experiences, connecting, the affinity-sensation network, and microorganisms. Students are led through activities and are asked to sense, enjoy, validate, match, resonate, appreciate and honor, trust, and celebrate a particular nature area. (KR)

The debate on the educational value of dissection versus the value of animal life is examined. Interactive videodisc (IVD) technology is described in light of its potential for laboratory simulations. The design of the IVD-based dissection simulation, The Interactive Frog Dissection, is presented. (KR)

An activity that introduces students to the concepts of independent assortment of alleles during meiosis and gametogenesis, the richness of the variation that occurs as a result of allele recombination, and the unique phenotypes of offspring. Reproducible handouts with the directions and model chromosomes are provided. (KR)

The preparation and format of debates that deal with environmental issues are presented. The educational pros and cons of such debates are discussed. A list of 30 suggested environmental debate topics and a reproducible debate evaluation form are provided. (KR)

The results of actual student participation, with organized group discussions, which show that laboratory teaching remains the premiere mechanism for teaching and learning organ-system physiology are discussed. Laboratories using a pithed frog, a turtle heart, an anesthetized rabbit, and noninvasive recordings from students during exercise are…

Describes the English Educational System, and contrasts the way physics is taught in the U.S. system on the following points: maturity, graduation requirements, laboratory work, student motivation, availability to students, and passage to higher education. (MDH)

Presents an experiment to investigate centripetal force and acceleration that utilizes an airplane suspended on a string from a spring balance. Investigates the possibility that lift on the wings of the airplane accounts for the differences between calculated tension and measured tension on the string. (MDH)
