Features a checklist of structural questions for writing a laboratory report discussion. Presents a rationale for this method of helping students organize their thoughts. (DDR)

The contemporary world of knowledge, characterized by an explosion of information and ways of communicating it, requires creativity more than ever in handling scientific knowledge. Thus, science education, especially for the gifted, must encourage the development of creativity. But, as creativity is not something that can simply be taught, we must…

Develops a simple tree-ring laboratory to demonstrate the basics of dendrochronology. Provides two upper-level laboratory exercises primarily intended to demonstrate the specific dendrochronology subdisciplines of dendroclimatology and dendroecology. Suggests using the exercises separately or in unison as part of a multidisciplinary capstone…

Describes the history of Richard Blakemore's discovery of magnetotaxic organisms. Discusses possible reasons why the magnetic response in bacteria developed. Proposes research experiments integrating biology and physics in which students investigate problems using cultures of magnetotaxic organisms. (MDH)

Presents a protocol that gives students hands-on experience in generating a meaningful physical map of a circular molecule of DNA. Topics include agarose gel electrophoresis, logic of restriction maps, extracting data from an agarose gel, managing data from gels, experimental protocol, loading gels, electrophoresis, photographing gels, collecting…

This classroom kit, designed by curriculum developers working with teachers and scientists from the SETI (Search for Extraterrestrial Intelligence) Institute, helps teachers guide students in the exploration of life through the multidisciplinary sciences of paleontology and exobiology. It reflects the real-life methods of science: making…

This teacher's guide on acid rain is divided into three study areas to explain: (1) what causes acid rain; (2) what problems acid rain has created; and (3) what teachers and students can do to help combat acid rain. Instructions for activities within the study areas include suggested grade levels, objectives, materials needed, and directions for…

Presents numismatic experiments that cover a range of topics that tie physical science and chemistry to society and history. Discusses measuring length; measuring mass; metals, alloys, and amalgams; reactivity of metals and electrochemistry; reactions of metals with acids; money to burn; magnetic properties of coins; inertia; refraction;…

Discusses the training and preparation for the transition to block scheduling. Provides a summary of some of the aspects of the four-by-four block schedule and describes strategies employed to modify instruction and curriculum. Includes two sample interdisciplinary activities. (DDR)

Materials, written on an approximate seventh-grade level, include: (1) a student reading unit; (2) water quality factors pamphlet; (3) experiments; and (4) teacher's guide to field testing a local waterway. The student reading unit is…

Describes a high school chemistry student's research project in which limonene was isolated from the oil of lemons and oranges. Outlines the students' tests on the use of this chemical as an insecticide. Discusses possible extensions of the exercises based on questions generated by the students. (TW)

These units were produced by a team exploring the possibility of developing some of the basic concepts of mathematics through simple, but significant physical science experiments. The purpose of the entire project is to see if learning and understanding of mathematics can be improved by the use of these science-related units in mathematics…
