Children and adolescents, up to approximately age 20, are more susceptible than adults to potential health risks from chemicals and environmental hazards. Hazardous chemicals can interrupt or alter the normal development of a child's body, leading to lasting damage. Since children are smaller than adults, similar levels of exposure to toxic…

Today's biology educators face the challenge of training their students in modern molecular biology techniques including genomics and bioinformatics. The Dolan DNA Learning Center (DNALC) of Cold Spring Harbor Laboratory has developed and disseminated a bench- and computer-based plant genomics curriculum for biology faculty. In 2007, a five-day…

Classical physics has a long history of using demonstrations and experiments to develop ideas in introductory courses. The purpose of this exploration is to examine the effectiveness of a desk-top activity for helping students develop abstract reasoning. In the pilot exploration, students in three laboratory sections of a single physics course…

Sustainability is a major issue when creating Websites that students use with courses. How will content change over time, how can faculty inexperienced with Web development add to and maintain content? This article will examine an implemented sustainable Website that can be managed by everyone associated with the course. (Contains 4 tables and 1…

As the number of new schools explodes in urban centers, educators need to understand the processes and challenges faced by schools trying to develop a central focus for curriculum and instruction. Using case study methods including interviews and document analysis, the current study explores the ways in which a highly successful magnet high…

We describe our experience in building a remote laboratory for teaching magnetic domains. Fulfilling the proposed on-line experiments, students can observe and study magnetization processes that are often difficult to explain with written material. It is proposed that networks of remotely accessible laboratories could be integrated in the Global…

The purpose of this study is to research the effect of the application of "reproduction, growth and development in living things" unit which takes place in the science and technology lesson programme of 6th grade students in the primary school to the success of the student by applying the laboratory method. Also another purpose is to…

Studies of protein function increasingly use multifaceted approaches that span disciplines including recombinant DNA technology, cell biology, and analytical biochemistry. These studies rely on sophisticated equipment and methodologies including confocal fluorescence microscopy, mass spectrometry, and X-ray crystallography that are beyond the…

This paper reports on a simple hands-on laboratory procedure for high school students in studying both radiation damage and DNA repair systems in bacteria. The sensitivity to ultra-violet (UV) radiation of both "Escherichia coli" and "Serratia marcescens" is tested by radiating them for varying time periods. Two growth temperatures are used in…

In high school, many students do not have an opportunity to learn or use statistics. Because statistics is a powerful tool and many students take a statistics class in college, prior exposure to statistics in a chemistry course (or another course) would benefit students. This paper describes some statistical concepts and tests with their…

The series of three sets of companion studies reported in this presentation addresses the need for seeking more effective outcomes from science laboratory experiences, which is indicated by conflicting outcomes of earlier reported research related to laboratory instruction at two different academic levels--grades 7-12 and beginning college. Four…

Spacelab is a facility which enables scientists and engineers to go into space for in-orbit research studies. For the 10 European nations that designed, constructed, and financed Spacelab jointly through the European Space Agency and for the National Aeronautics and Space Administration, which designed, constructed, and financed the Spacelab…

Describes a model for a college biology laboratory that is: (1) individualized, (2) self-instructional, and (3) investigative. (See also SE 515 093.) (LS)

Describes the following uses of computers in college biology laboratories: (1) to organize and analyze research data and (2) to simulate biological systems. Also being developed are computer simulations to systematically prepare students for independent investigations. (See also SE 515 092.) (LS)

Describes the design and materials for an elementary school science laboratory which can be installed for approximately $3,000. (MLH)
