Presents a science activity on cellular mitosis for middle school students. (YDS)

According to the National Science Education Standards (National Research Council 1996), students in the middle school years should progress in studying life science from examining individual organisms to recognizing patterns in ecosystems and developing an understanding about the cellular dimensions of living systems. Students should broaden the…

This guide is designed to foster an understanding of the basic concepts underlying biotechnology through simple activities that are fun and creative for students in grades 3-5. It contains four units that will lead young students to an appreciation of how biotechnology is possible and some of its applications. The process of learning is intended…

Project AIMS (Activities to Integrate Mathematics and Science) has as its purpose the integration of subject matter in grades K-9. Field testing of the curriculum materials produced by AIMS indicates that this interpretation produces the following beneficial results: (1) mathematics becomes more meaningful, hence more useful; (2) science is…

Describes how to construct a model of a DNA molecule with inexpensive materials. (BR)

A number of activities are described by which a class can collect biological data about the students in the class. Brief instructions are given. (RH)

Summarizes physics laboratory experiments with applications in the biological sciences. Includes the following topics: mechanics of the human arm, fluid flow in tubes, physics of learning, the electrocardiograph, nerve impulse conduction, and corrective lenses for eye defects. (Author/MLH)

Nine questions are presented for student discussions relating to genetics, evolution, and racial characteristics. A brief introductory discussion of these topics are presented, as well. (BB)

Described are nutritional studies that can be incorporated into elementary biology courses. Included are suggested experiments concerning physical change, chemical change, and microbiological change. (SL)

A description of four rapid tests to determine the viability of stored seeds are given. Typical results are reported and some possible applications of the tests are discussed. (Author/EB)

This activity is used to introduce students to biology in general and the significance of environmental studies. The focus of the ecosystem survey is to examine the effects humans have on the environment. After completing a series of investigations, students develop their own hypothesis about human impact on the environment, and then test this on…

This activity features students carrying out an outdoor study of a 10-by-10 meter area in which they identify organisms living in the soil, plants, insects, and any other animals living within or immediately adjacent to the site. Groups also examine abiotic factors in the same study site. Students work in teams, share data, and each write a paper…

Describes a surgical technique for performing pinealectomics, applicable to classroom and laboratory studies, by using a head-holding device for small animals and a flat dissecting tray outfitted with holding straps for larger animals. (CC)
