This booklet discusses some of the basic facts about nuclear energy and provides eight experiments related to these facts. The experiments (which include lists of materials needed and procedures used) involve: (1) an oil-drop model of a splitting atom; (2) a domino model of a chain reaction; (3) observing radioactivity with an electroscope; (4)…

Describes how to construct a simple pendulum seismometer. Includes schematic drawing of the electronic circuitry, a working drawing of the apparatus, and typical seismometer outputs caused by nearby trains and various earthquake-generated waves. (JJK)

Introduces the basics of radio astronomy and describes how to assemble several simple systems for receiving radio signals from the cosmos. Includes schematics, parts lists, working drawings, and contact information for radio astronomy suppliers. (11 references) (Author/JJK)

Organizations such as the Ohio Academy of Science sponsor programs to encourage junior and senior high school students to conduct science projects. These programs are designed to give students who might pursue careers in technical areas a realistic foretaste of some of their future professional responsibilities, including the effective…

Presented are various activities and projects intended to help Boy Scouts earn a merit badge in oceanography. Each project and/or activity is related to a requirement (objective) found in a list at the beginning of the booklet. Topic areas and/or related activities and projects include: (1) nature of oceanography (naming oceanography branches,…

The authors describe a simple forecasting strategy that focuses on environmental and global topics. Students choose their own topics, collect and analyze data, make predictions, and present findings to the class. Authors claim the following advantages of forecasting: students become motivated; work in cooperative groups; increase skills in…

Information for preparing technical reports is presented in this guide. This information includes: (1) descriptions of a technical report, an abstract, and a technical paper; (2) guidelines for writing abstracts and technical reports; (3) guidelines for developing an outline; (4) a sample student report format; and (5) a technical report appearing…

Describes an electronic circuit that can function as a prototype for chaotic systems. Specific applied voltages produce chaotic signals that can be viewed with an oscilloscope or be made audible with a home stereo system. Provides directions for assembly with typical costs, mathematical basis of chaos theory, and experimental extensions. (JJK)

Describes how teachers and students can conduct a schoolwide hazardous waste survey. The activity is an introduction to hazardous waste management and is useful in general physical science, chemistry, and environmental science classes. Two activity worksheets are provided. Explains how schools can clean up hazardous waste problems. (PR)

Discusses composting of organic materials as an alternative to landfills. Lists uses of composts and describes details of a simple composting activity for high school students. Includes an information sheet for students and a student data sheet. Suggests other composting activities. (PR)

Provides construction details for a simple reflectometer that can be utilized for the observational technique known as reflectance spectroscopy. Includes background discussion, applications, calibrating techniques, and typical results. (JJK)

Provides the electronic circuit schematic for the construction of a green vegetation sensor, the directions for its use, and suggestions for student projects. (JJK)

Presented is a guide for students planning to do a science project. Discussed are preliminary organizational matters, report plans, choosing topics, setting up procedures, time management, and documentation. The most important steps for producing a successful project are summarized. (CW)

Background information, lists of materials needed, and detailed procedures are provided for five science projects. These projects involve constructing and using: (1) an electric pencil; (2) a buzzer to send coded messages; (3) a battery which produces light; (4) a radio that plays for free; and (5) a supersensitive cigar-box microphone.
