Described are several activities for teaching children to determine mass and volume. Included are the masses of a water drop and a grain of rice; the volume of a water drop and small solids; and measuring the width of a hair. Procedures and materials for the activities are discussed. (CW)

Describes two simple methods of error analysis: (1) combining errors in the measured quantities; and (2) calculating the error or uncertainty in the slope of a straight-line graph. Discusses significance of the error in the comparison of experimental results with some known value. (MDH)

Presents a framework for teachers to use the thermodynamic system of popping corn to generate student interest. Examines the popping mechanism and the role of steam in, the heat required during, and the energy efficiency of the popping process. (MDH)

Describes an activity measuring the amount of dissolved carbon dioxide in carbonated water at different temperatures. The amount of carbon dioxide is measured by the amount of dilute ammonia solution needed to produce a pH indicator color change. (PR)

Describes four instructional techniques used to deliver specific developmental objectives in both an introductory chemistry course and a general course in science and technology. The four techniques described are miniresearch projects, scenario-based research projects, short essay examination questions, and issues-directed research project. (PR)

Describes using picture books and science activities in early childhood science instruction. Suggests titles of books and activities for the following topics: Time for Pets; Environmental Awareness; Dinosaurs Galore; Nighttime Science; Simple Machines; Insect Collections; Snowy Days; Water, Water, Everywhere; and Experimental Activities. (PR)

Describes a field study in a local ecosystem which allows high school students to investigate the edge effect, where a meadow and a forest meet. Students measure soil moisture content, soil temperature, air temperature, relative humidity, wind intensity, and illumination level. Teachers can help students apply their findings to understand problems…

Discusses integrating mathematics/science with measurement for grades 6-12. Provides Web addresses for companies manufacturing data grabbers (instruments for gathering data in electronic form for graphing and analysis by graphing calculators and computers) and for sites offering instructional materials. Describes projects in architecture,…

This paper offers some concrete ideas and suggestions for incorporating discussions of experimental technologies in the middle level technology education classroom. Technology education students should be aware of experimental technologies. They should understand the ramifications of items such as hybrid vehicles, photovoltaic solar panels,…

This article describes how Cahokia middle and high school students conduct inquiry-based science through a pitfall trap experiment. In a collaborative effort, students designed and conducted pitfall trap investigations that combined their interest in the natural world with their love of technology. The students set up their own experiments to…

This article addresses an impasse in debates about online education in university education. One side presents a story of the progressive development of technology as it is applied to the organisation of higher education, leading to pedagogical advances and to the new forms of administration required for the realisation of the technology's full…

Active learning and research-oriented activities have been increasingly used in smaller, specialized science courses. Application of this type of scientific teaching to large enrollment introductory courses has been, however, a major challenge. The general microbiology lecture/laboratory course described has been designed to incorporate published…

This project, "Many Right Answers: Learning in mathematics through speaking and listening", was initiated to address two issues in the teaching of secondary mathematics: (1) speaking and listening and its relevance to engaging the disengaged; and (2) the use of speaking and listening by teachers of mathematics as part of their Continuous…

Investing in technology is investing in America's future. U.S. technology must move in a new direction to build economic strength and spur economic growth. The traditional roles of support of basic science and mission-oriented technological research must be expanded, so that the federal government plays a key role in helping private firms develop…

This monograph is a rich resource of information designed to strengthen science and basic skills teaching, and improve learning for limited English proficient (LEP) minority student populations. It proposes the use of hands-on science investigations as the driving force for mathematics and English language development. The materials included in…
