The term "restriction endonuclease mapping" covers a number of related techniques used to identify specific restriction enzyme recognition sites on small DNA molecules. A method for restriction endonuclease mapping of a 1,000-basepair (bp)-long DNA molecule is described in the fictitious experiment of this test. The most important fact needed to…

The Lawrence Hall of Science, a science center, seeks to replicate real-world engineering at the "Ingenuity in Action" exhibit, which consists of three open-ended challenges. These problems encourage children to engage in engineering design processes and problem-solving techniques through tinkering. We observed and interviewed 112…

We hereby present the main conclusions and perspectives obtained by the Group of Teaching Innovation in Electronics (Grupo de Innovación Docente en Electrónica, GIDEN) of the University of Valladolid (UVa) with regard to its main areas of work. This group comprises teachers of the "Specialty in Industrial Electronics" degree, and the…

In seven chapters, this report details the Science Fair Self-Help Development Program, which was initiated in a pilot project at three middles schools in Albuquerque, New Mexico, during school year 1991-1992. The purpose of the program was to provide guidance to schools in developing their own parental and community resources into a sustainable…

In a study to evaluate an approach for improving the critical thinking skills of middle school science students, 60 students were given the assignment of completing three guided laboratory activities and writing a report for each. In writing their reports, students were expected to identify the manipulated variable, identify the responding…

The many activities contained in this teaching guide emphasize hands-on involvement, prediction, data collection and interpretation, teamwork, and problem solving. The guide also contains background information about aeronautical research that can help students learn how airplanes fly. Following the background sections are a series of activities…

The Integrated Occupation Science 26 Program is an optional program designed to allow students in Alberta, Canada to meet the credit requirements of the Certificate of Achievement and facilitate transfer to the General High School Diploma Program. This Teacher Resource Manual is provided to assist classroom teachers to implement the Science 26…

NASA (National Aeronautics and Space Administration) Engineers at Marshall Space Flight Center along with their partners at other NASA centers, and in private industry, are designing and beginning to develop the next generation of spacecraft to transport cargo, equipment, and human explorers to space. These vehicles are part of the Constellation…

Reported is an instrument, the Science Student Observation Instrument (SSOI), designed for use in activity-centered science classes in desegregated urban junior high schools. Use of the instrument will enable the observer to compare classroom behaviors of black and white students, to determine the extent of interracial interactions, and to…

The construction of the International Space Station (ISS) is one of humankind's most exciting and challenging endeavors. Numerous rocket launches are required to build this orbiting science laboratory. The purpose of this curriculum supplement is to introduce students in the Early Childhood classroom to the International Space Station and the role…
