Estuarine Oceanography is one in a series of single-topic problem modules intended for use in undergraduate and earth science courses. Designed for those interested in coastal oceanography or limnology, the module is structured as a laboratory supplement for undergraduate college classes but should be useful at all levels. The module has two…

Presented is one of a series of resource guides designed to provide students with an improved mathematics program. This guide emphasizes hands-on experiences for secondary students through real-life situations focusing on measurement in the home. Students are provided with numerous opportunities to use both customary and metric units in…

The Council of Europe is based on the principle that each member state is responsible for its use of foreign labour and for determining the number and nature of such workers to meet the needs of its own economy. Therefore, the Council has never assumed the task of organising the free movement of manpower nor of encouraging movements of workers in…

In February 1968, the Social Studies Implementation Project began as a cooperative venture involving twenty-three school districts in metropolitan St. Louis. The overall objective of the project was to operate a model which was designed to overcome the problems of curriculum implementation. Operationally, the project had several objectives: 1) to…

Describes two demonstrations to illustrate characteristics of substances. Outlines a method to detect the changes in pH levels during the electrolysis of water. Uses water pistols, one filled with methane gas and the other filled with water, to illustrate the differences in these two substances. (TW)

Describes an activity in which students collect airborne particles using a common vacuum cleaner. Suggests ways for the students to convert their data into information related to air pollution and human health. Urges consideration of weather patterns when analyzing the results of the investigation. (TW)

Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

Describes two laboratory demonstrations in chemistry. One uses dry ice, freon, and freezer bags to demonstrate volume changes, vapor-liquid equilibrium, a simulation of a rain forest, and vaporization. The other uses the clock reaction technique to illustrate fast reactions and kinetic problems in releasing carbon dioxide during respiration. (TW)

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)

Reports on a study into the effectiveness of implementing an interactive videodisc science lesson on titration into a high school science program. Describes the titration lesson and the equipment used in two chemistry classes. Results were generated from achievement and attitude instruments, along with observational data. (TW)

Lists five experiments or demonstrations involving hypodermic syringes. The titles of experiments are Boyle's Law, Charles' Law, Atmospheric Pressure, Expansion of Gases, and Boiling at Reduced Pressure. Provides a list of materials, the typical data, and graphs where appropriate. (YP)

Presented is the use of a microprocessor for mechanics experiments. Described are the experimental set-ups, experimental method, and conclusions. Includes several diagrams and pictures. (YP)

Describes an introductory chemistry experiment that can be used for lead-in discussions for a variety of topics. Stresses this experiment's ease because of measuring simplicity and familiarity of materials, and its value of reinforcing proper observation and recording techniques while getting students to think about techniques and concepts of…

Discusses the establishment of a high school chemistry instrumentation center designed to retrain teachers, improve precollege preparation of high school chemistry students, and to make simple chemical instruments at a minimal cost. (TW)

Discusses the goals of learning cycle laboratories in helping students acquire knowledge about a specific topic and to do so moving in a non-threatening way from the concrete operational level to the formal operational level. Describes an experiment designed for such laboratories dealing with the topic of oxidation-reduction. (TW)
