In every drop of water, down at the scale of atoms and molecules, there is a world that can fascinate anyone - ranging from a non-verbal young science student to an ardent science-phobe. The objective of Learning Science Through Guided Discovery: Liquid Water & Molecular Networks is to use advanced technology to provide a window into this submicroscopic world, and thereby allow students to discover by themselves a new world. We are developing a coordinated two-fold approach in which a cycle of hands-on activities, games, and experimentation is followed by a cycle of computer simulations employing the full power of computer animation to "ZOOM" into the depths of his or her newly- discovered world, an interactive experience surpassing that of an OMNIMAX theater. Pairing laboratory experiments with corresponding simulations challenges students to understand multiple representations of concepts. Answers to student questions, resolution of student misconceptions, and eventual personalized student discoveries are all guided by a clear set of "cues" which we build into the computer display. Moreover, the ability to visualize "real-time" dynamic motions allows for student-controlled animated graphic simulations on the molecular scale and interactive guided lessons superior to those afforded by even the most artful of existing texts. While our general approach could be applied to a variety of topics, we have chosen to focus first on water; later we will test the generality of the approach by exploring macromolecules such as proteins and DNA. The simulation sofware we have been developing embodies a simple molecular interaction model but requires leading edge computing in order to (1) apply the model to large enough systems to yield simple and realistic behavior, and (2) animate the result in real time with advanced graphics. Our ultimate goal in this project is not only to help students learn science, but also to help them learn to think like research scientists. By looking at scientific knowledge as a set of useful models - models that are essentially temporary and will inevitably lead to better ones - they can see that science is not a set of facts, but a method for discovering patterns and predictability in an otherwise disordered and unpredictable world. Through mastery of the simulation software, students will gain the self-confidence to embark on their own missions of discovery.
Digital image processing offers several possible new approaches to the teaching of a variety of mathematical concepts at the middle-school and high-school levels. There is reason to believe that this approach will be successful in reaching some "at-risk" students that other approaches miss. Since digital images can be made to reflect almost any aspect of the real world, some students may have an easier time taking an interest in them than they might with artificial figures or images resulting from other graphics- oriented approaches. Using computer-based tools such as image processing operators, curve-fitting operators, shape analysis operators, and graphical synthesis, students may explore a world of mathematical concepts starting from the psychologically "safe" territory of their own physical and cultural environments. There is reason to hope that this approach will be particularly successful with students from diverse backgrounds, girls and members of minority groups, because the imagery used in experiments can easily be tailored to individual tastes. The work of the project consists of creating detailed designs of the learning modules, implementing them on microcomputers, and evaluating their effectiveness in a variety of ways, using trials with students at Rainier Beach High School, which is an urban public high school having an ethnically diverse student body and a Macintosh computer laboratory.

The Numbers Alive project will model the use of number sense and provide opportunities for its practice through the production of ten half-hour television programs for students, one program for parents and care-givers, and print materials in support of both types of programs. The targeted student audience is fifth and sixth graders. The print materials supplement the televised programs. The series emphasizes number concepts and problem solving strategies in support of the NCTM Standards.
This is a request from Claypoint Productions for 124,700 of a total budget of $526,178 to produce a one-hour prime-time documentary program on the Wright Brothers, the processes of science and engineering used in their work, and the science and technology behind their development of the airplane. The PBS program will cover the subjects of aerodynamics, aeronautics, geometry, algebra, applied mathematics, mechanical engineering, the process of invention, and the history of technology. A teacher's guide will be developed to supplement the film.
The excitement of astrophysical research and discovery is brought into the high school science and mathematics classes through a flexible set of student activities and projects on variable stars. The project includes a computerized database, of 400,000 measurements of brightness of 150 variable stars in five constellations over 25 years, from which students can deduce properties, processes, and evolution of these stars. Students can make additional measurements and discoveries from carefully selected time sequences of 125 35mm slides or from actual measurements from the night sky. A comprehensive student manual and instructional videos make the materials self-contained and easy to use. The teacher manual enables the instructor to adapt the materials to skills, objectives and local curricula. The material can be used in a variety of contexts: traditional mathematics and science classes at both the high school and college level, independent projects, summer institutes, and community science clubs. The material will be field tested in classes and refined through workshops with teachers. A newsletter and a video about amateur astronomers is planned.
This exhibit will integrate graphics, artifacts, highly interactive electro-mechanical demonstration devices together with state of the art interactive educational computer technology to demonstrate how probability shapes nature. It will draw its examples from a variety of scientific fields including physics, chemistry, earth sciences, and biology. It is planned as a permanent addition to the Museum's exhibition program, but will be designed to facilitate easy reproduction for individual copies or for circulation as a travelling exhibit. Millions of visitors--families, teachers, children form diverse communities--will gain a first hand aesthetic appreciation of the pattern finding process of scientific investigation as well as a better understanding of the usefulness of mathematics in explaining how the natural world works.

As the world's largest single-dish radio telescope, Arecibo Observatory in Puerto Rico attracts thousands of visitors each year, of all ages and from many countries. Pride in the Observatory has caused local Puerto Rican organizations to contribute the funds necessary for the construction of the new Arecibo Observatory Visitor and Educational Facility. Cornell University, in behalf of the National Astronomy and Ionosphere Center, is requesting $774,463 form the NSF-ISE over a two year period to develop and implement the exhibits and educational programs which will give life to the Educational Facility. Within the facility, we propose establishing an educational program centered on the theme "More Than Meets the Eye", which will reflect the general idea that we can study our world with tools which extend our direct sensory experience. The proposed program will explore the unseen sky and, in particular, the objects that fall under the scrutiny of a radio telescope. Specifically, the program will introduce the visitors to the electromagnetic spectrum as a means of exploration, will offer a framework of basic astronomy and atmospheric science, and will provide understanding of the function and operation of the Arecibo radio telescope. Some of Arecibo's most exciting new discoveries in the fields of radio astronomy, solar system radar astronomy and astomospheric science will be presented so that visitors can experience the dynamic nature of science.
"Atmospheric Explorations: Participatory, Computer-Based Simulations of the Weather" is a collaborative project of Augsburg College and the Science Museum of Minnesota. The purpose of the project is to enhance the interest and skills of museum visitors and students in science by providing a highly interactive exhibit environmental that allows the users considerable freedom in exploring topics in meteorology relevant to their everydays lives. The exhibits will be designed to accommodate a gender- and racially-diverse audience of national scope.

The AAAS Black Church Health Connection Project, with funding from the National Center for Research Resources (NCRR), has developed and field tested a guidebook/manual of hands-on and participatory life science activities and a training/orientation program for use in non-religious education programs in churches that serve the African-American community. The current dissemination efforts of the project have led to increased demands for the activity manual and subsequent training for persons seeking to implement the program. AAAS was awarded additional funding to: (1) Continue dissemination of the project in the African-American community; (2) Expand the project to the Hispanic American community; and (3) Identify and connect biomedical/behavioral scientists to churches and community-based organizations seeking to improve health awareness among African Americans and Hispanic Americans. Products of this dissemination effort include a Spanish version of the Health Connection Activities Guidebook/Manual, a video training kit in both English and Spanish to assist communities in implementing the project, and a database of scientist volunteers who are interested in working with churches and community-based organizations to impact the quality of health science education in the aforementioned communities.
