This article reports on part of a larger study of how 11- and 12-year-old students construct knowledge about electricity and magnetism by drawing on aspects of their experiences during the course of a school visit to an interactive science museum and subsequent classroom activities linked to the science museum exhibits. The significance of this study is that it focuses on an aspect of school visits to informal learning centers that has been neglected by researchers in the past, namely the influence of post-visit activities in the classroom on subsequent learning and knowledge construction

This award is for a Science and Technology Center devoted to the emerging area of nanobiotechnology that involves a close synthesis of nano-microfabrication and biological systems. The Nanobiotechnology Center (NBTC) features a highly interdisciplinary, close collaboration between life scientists, physical scientists, and engineers from Cornell University, Princeton University, Oregon Health Sciences University, and Wadsworth Center of the New York State Health Department. The integrating vision of the NBTC is that nanobiotechnology will be the genesis of new insights into the function of biological systems, and lead to the design of new classes of nano- and microfabricated devices and systems. Biological systems present a particular challenge in that the diversity of materials and chemical systems for biological applications far exceeds those for silicon-based technology in the integrated-circuit industry. New fabrication processes appropriate for biological materials will require a substantial expansion in knowledge about the interface between organic and inorganic systems. The ability to structure materials and pattern surface chemistry at small dimensions ranging from the molecular to cellular scale are the fundamental technologies on which the research of the NBTC is based. Nanofabrication can also be used to form new analytical probes for interrogating biological systems with unprecedented spatial resolution and sensitivity. Three unifying technology platforms that foster advances in materials, processes, and tools underlie and support the research programs of the NBTC: Molecules of nanobiotechnology; Novel methods of patterning surfaces for attachment of molecules and cells to substrates; and Sensors and devices for nanobiotechnology. Newly developed fabrication capabilities will also be available through the extensive resources of the Cornell Nanofabrication Facility, a site of the NSF National Nanofabrication Users Network. The NBTC will be an integrated part of the educational missions of the participating institutions. NBTC faculty will develop a new cornerstone graduate course in nanobiotechnology featuring nanofabrication with an emphasis on biological applications. Graduate students who enter the NBTC from a background in engineering or biology will cross-train in the other field by engaging in a significant level of complementary course work. Participation in the NBTC will prepare them with the disciplinary depth and cross-disciplinary understanding to become next generation leaders in this emerging field. An undergraduate research experience program with a strong mentoring structure will be established, with emphasis on recruiting women and underrepresented minorities into the program. Educational outreach activities are planned to stimulate the interest of students of all ages. One such activity partnered with the Science center in Ithaca is a traveling exhibition for museum showings on the subject of nano scale size. National and federal laboratories and industrial and other partners will participate in various aspects of the NBTC such as by hosting interns, attendance at symposia and scientist exchanges. Partnering with the industrial affiliates will be emphasized to enhance knowledge transfer and student and postdoctoral training. This specific STC award is managed by the Directorate for Engineering in coordination with the Directorates for Biological Sciences, Mathematical and Physical Sciences, and Education and Human Resources.
In-Touch Science provides informal learning experiences to help children ages 8 to 11 understand the science in their everyday lives. Each science theme is introduced through a hands-on activity in one subject area and is reinforced through a second experience based in a different field of science. By linking concepts common to the paired fields, the program teaches children to make connections between what they've learned in one context and what they observe in another arena. The program targets children enrolled in special needs programs, 4-H clubs, school-age child care facilities, and home schooling. The program engages, supports and sustains community science facilitators, the majority of whom are not experienced educators. They will be trained to work with the children, using the Learning Cycle, a guided discovery strategy. Cornell developed the curricula for three paired disciplines: 1) Engineering and Plant Science, 2) Animal Science and Fiber Science, and 3) Chemistry and Environmental Science. Instructional materials for the project consist of three curricula, a facilitator-training guide, and supply kits.

The New York Hall of Science will develop, test, and implement the "Biochemistry Discovery Lab," a 1000-sq.-ft. space designed to complement the content and design of "The Chemistry of Living Things," a 3000-sq.-ft. exhibition that will be opening in 1999. The Biochemistry Discovery Lab will engage visitors in four different types of activities: 1) guided experiments for scheduled groups, 2) self-guided experiments, 3) demonstrations, and 4) the prototyping of ancillary materials. These activities are intended to engage the target audiences -- families, students, and the general public -- in experiences leading to an understanding that chemical reactions are due to the interaction of molecules; that chemical reactions occur in both living and nonliving things; and that there are visible and measurable characteristics of chemical reactions in living and nonliving systems.
The New York Hall of Science will develop an interactive exhibit for the general public "The Chemistry of Life". There will be two editions of the exhibit: one 2,500 sq. ft. version will be installed permanently in the New York Hall of Science and another 1500 sq. ft. version will travel nationally. Focusing on the common chemical processes behind all life on earth, the exhibit will help visitors learn four basic chemistry concepts: 1) a shared chemistry underlies all forms of life, 2) the chemistry of energy transformation takes place in all living things, 3) chemical energy is converted to mechanical energy to animate life, and 4) the chemistry of reproduction provides for the continuity of life. The chemistry of the human body will be used whenever possible as an entry point to the concepts. Exhibits will include a hands-on staffed visitor chemistry lab, interactive activities, stimulations, models, demonstrations, and video clips. Complementary materials and workshops will be developed for families, school groups, and teachers. These materials are being developed with the curricular needs of the New York State Systemic Initiative and New York City Urban Systemic Initiative in mind. Teacher and student materials will be keyed to the curriculum guidelines. The long-term exhibit is scheduled to open late in 1998 and the traveling version will be available in spring 1999.
The Materials Research Society will develop "Materials MicroWorld." This will be a nationally traveling exhibition that promotes public understanding of basic scientific principles, issues, and trends in materials research. "Materials MicroWorld" will be developed in two exhibit versions, 5000-sq.ft. and 1500- sq.ft., to serve large and small science centers nationwide. Accompanying educational materials and training videos will enable each museum to tailor exhibit-related programming to suit the needs of audiences and the capabilities of staff. An electronic 'Best of Materials Science Activities ' booklet will be developed for publication on the Materials Research Society website to deepen understanding of exhibit concepts and provide parents and educators with a variety of explorations on materials science that can be safely conducted at home or in school.
KCTS, the public broadcasting station in Seattle, WA, is producing and distributing15 new half-hour episodes for the children's television series, Bill Nye the Science Guy.

WGBH is producing four, two-hour programs on the lives of scientists. These programs will be the initial programs in a continuing series of television portraits of distinguished scientists to be broadcast as regular features in the prime-time science series NOVA. The scientists to be covered in the first four programs are Galileo Galilei, Charles Darwin, Marie Curie, and Percy Julian. By illuminating the lives and scientific careers of these important figures, the programs will enhance public understanding of such basic scientific concepts as evolution, the solar system, the chemical bond and the structure of the atom. Ultimately, the programs will give viewers a new perspective on the process of scientific discovery. Ancillary educational support for the programs will include enhanced content on the web site at NOVA Online and classroom support material in the NOVA Teacher's Guide that is mailed to 60,000 teachers nationwide. WGBH also has formed an outreach partnership with the American Library Association to create informal educational resources for use by families, youths, and adults. The core of this special outreach plan is a set of Library Resource Kits that will be available to all 16,000 public libraries. Paula Apsell, Executive Producer for NOVA, will serve as PI for the project.
