Presents a problem involving the double-slit interference pattern that relates to the real-world situation of guiding an aircraft to a safe landing. (JRH)

Describes the construction and use of an electrooptic apparatus that can be incorporated into the classroom to test liquid crystal displays (LCDs) and introduce students to experiments of an applied physics nature with very practical implications. Presents experiments that give students hands-on experience with technologies of current interest to…

Presents a problem in which the incorrect application of the Law of Sines leads to an erroneous solution. Demonstrates that the commission of this error by an ophthalmologist using laser trabeculoplasty could lead to patient injury. (MDH)

Activities used to teach optics to fifth and sixth graders are presented. Moon phases and solar and lunar eclipses are included. (SA)

An introductory Natural Science course with a focus on the laboratory is described. The main function of the course is getting students prepared for required individual projects in science. A copy of the syllabus, a description of laboratory experiments, and the context of the course are included. (KR)

There are many reasons for studying Antarctica. It is the key element in the world's climate. Some of the secrets of the earth's past are locked beneath its icecap. It has a fascinating physical environment and a unique and fragile ecosystem. It is a frontier of scientific research and technological development. Its history is an important and…

This document is intended to help teachers prepare students to perform the duties of any member of a surveying party, including those of party chief, in the field and in the office. It contains instructional units on introduction to surveying, safety, horizontal measurements, vertical measurements, angles and directions, angular measurements,…

Presents examples of physics activities using common objects such as a tuning fork, umbrella (for double diffraction patterns), and a toy car. Provides questions designed to stimulate student curiosity/interest and which provide models for developing additional units on everyday objects and toys. (JM)

Preservice elementary teachers worked cooperatively to explore the relationship between the measure of the central angle and the number of sides of regular polygons using the reflection of a line in a hinged mirror. The experience involved conjecture and experimentation, communication, and building connections between science, geometry, and…

The curriculum materials contained in this document were developed through a cooperative effort by educators in the state of Maryland. It was a curriculum project aimed at the meaningful integration of mathematics and science. It is suggested that these materials be used in two significant ways. First, this document can serve as an instructional…
