In this article, Minda Borun of the Franklin Institute Science Museum discusses the museum's eighteen month study to discover visitors' misconceptions about gravity and air pressure and to develop exhibits which help people restructure these concepts and achieve an understanding of the scientific explanation. The project is intended to establish a new model for the design of effective science museum exhibits.
The St. Louis Science Center is a major metropolitan science museum serving a population of 2.3 million people. One year ago they moved into a new facility at a new location and attendance at the museum has tripled, reaching 600,00 visitors this past year. The center will develop a "Science Playground" in order to teach basic science principles and process through a series of 45 outdoor participatory exhibitions around the major areas of motion, energy, light, sound and the natural environment. The physics of motion will be explored through exhibits such as a friction slide, lunar gravity swing, double-axis human pendulum, etc. Energy exhibits will provide experiences with watermills and water power, fulcrum leverage and solar energy. Light exploration includes a solar column, prisms and rainbows, soundwheel and whisper discs. A weather station will have a rain gauge, anemometer, a variety of barometers, etc. This contemporary playground concept was developed as a response to limitations of indoor facilities and to extend use of outdoor space in a creative manner. The exhibit will be a model for extending science learning opportunities for schools, parks, other science museums and similar institutions. The center surveyed 31 science centers, 82 parks and 85 school districts to gauge interest in use of science playground exhibits, and found a clear interest in this type of project by all sectors surveyed. Exhibit designs will be published and furnished at cost to any facility wishing to replicate all or any part of the exhibition.

This project is aimed at perfecting and testing a new instructional method to improve the effectiveness of introductory physics teaching. the methods has two chief characteristics: 1) a systematic challenge to common sense misconceptions about the physical world, and 2) an emphasis on models and modeling as basic to physical understanding. Two versions of the method will be tested. The first version is designed especially for high school physics. It emphasizes student development of explicit models to interpret laboratory activities. After an initial test, this version will be taught to high school physics teachers in a summer Teacher Enhancement Workshop, and its effect on their subsequent teaching will be evaluated. Teachers with weak as well as strong backgrounds will be included. A special effort will be made to include females and minorities. The second version will be tested in a special college physics course designed to prepare students with weak backgrounds for a standard calculus based physics course. It emphasizes modeling techniques in problem solving. This project is jointly supported by the Division of Materials development, Research and Informal Science Education and the Division of Teacher Preparation and Enhancement.
The Children's Museum proposes to develop two versions of an interative physical.science exhibit dealing with wave mechanics and the related actions of vibrating and oscillation systems. One version will be a permanent exhibit that is to be a central component in the new science area of the museum, while the other will be a traveling exhibit that will tour the country under the auspices of the Association of Science.Technology Centers. The purpose of the exhibit is to heighten the interest of children in scientific experimentation, with learning taking place at three levels including sensory.motor, perceptual.operational and intutitive.conceptual. Materials for teachers will supplement the exhibit, and an internship program will train largely minority middle.school students in basic concepts and then use them as "explainers" for the general public. The request to the National Science Foundation represents 73% of the total cost of the exhibits, with the remainder coming from institutional and other sources.
The New York Hall of Science will develop a major exhibition on quantum theory--one of the most important developments in physical science in this century and one which has not been significantly treated by science museums. This exhibition will be the first major museum program to introduce quantum theory and its applications to the public. Elements of the exhibit will include models of the atom, the puzzle of light, applications of the theory and, finally, the human story of the creation of a new theory. Numerous participatory exhibits will be developed in conjunction with the project so that visitors can learn by doing. Formative evaluation will be an integral part of this exhibit. This technique has recently been adopted by museums as a way to test exhibit prototypes with museum visitors and then redesign as necessary. A workshop will be held for museum personnel and a guidebook, Improving Exhibits Through Formative Evaluation, will be produced. This book will be the first complete description of the formative evaluation process and will be a valuable addition to the museum field.
The investigation of naive conceptions of science has many implications for both teaching and learning. The predominant model for past investigations has been with school children or within very formal settings. Extending investigations of misconceptions to informal settings is the challenge of this research. Museum visitors' misconceptions about two topics, gravity and mechanical advantage, will be recorded through a variety of interview formats. Twenty-five persons from each of the age ranges 9-11, 12-14, 15-18, and college students/adults will be interviewed. Information from the interview will be used to modify the current exhibit or to build new prototypes. The research will determine if a modification can be made that results in individuals moving from their previous misconceptions toward a correct conceptualization of the concepts. This research will document what individuals actually learn from museum exhibits and how "front end evaluation" can be used to redesign exhibits for maximum concept learning. The proposed research is challenging and has the potential of adding significant information to science education research on misconceptions. The principal investigator is highly respected in the field of museum education and the associated staff and consultants are the top scholars in their respective fields.
The Franklin Institute Science Museum will design, test, fabricate, and circulate to eight museums an exhibit, "The Science of Music: Sound Waves and Sound Forms" that will introduce visitors to the physical laws that govern sound waves. By using music as an attractive and concrete subject to engage broad public interest, the exhibit will illustrate such topics as sound wave amplitude, phase, frequency, reflection and interference. Primary support for the project comes from the eight member Science Museum Exhibit Collaborative, consisting of: the Franklin Institute Science Museum, Philadelphia, PA; Discovery Place, Charlotte, NC; the Fort Worth Museum of Science and History, Fort Worth, TX; the California Museum of Science and Industry, Los Angeles, CA; the Science Museum of Minnesota, St. Paul, MN; the Museum of Science and Industry, Chicago, IL; the Center of Science and Industry (COSI), Columbus, OH; and the Museum of Science, Boston, MA. Each has contributed $50,000 and the costs of exhibit shipping and maintenance. Direct matching fund support totals more than $381,000. The exhibit will spend three months in each location, and the total audience will exceed 1.5-million visitors over its eight museum tour. This project will extend the work of a group of museums that are already helping each other in a collaborative effort. The exhibit concept has high public appeal among groups that science finds it hard to reach, including teenagers and minorities. An FY87 award of $145,000 is recommended.
The Science Museum of Minnesota will develop a series of "experiment benches" that are to be an unique feature of "labworks," a major new hall of physical science and technology. The small bench-top laboratory exhibits will allow visitors to create their own experiments and to become informally but directly involved in the experimental process. The target audience is junior highschool students, especially those who come as individuals and who are repeat visitors. Selected students will be trained as interns and will be paid to act as mentors for visitors. The project will include a published report, "a recipe book" for dissemination, and a subsequent conference of exhibit developers from other science museums.
The Thames Science Center collaborative with the resources of the Smithsonian Astrophysical Observatory, Wesleyan University and the National Air and Space Museum will design and develop the project, "Shoot For the Moon." This science education project will capitalize on the attraction, familiarity and proximity of the moon using it as a basis to enrich and supplement the eight and ninth grade physical science curriculum. Ten classroom units, complimentary experiments and demonstrations will be developed. "Moonwatch" software and audio visual materials, including an instructional videotape and a multi.image presentation will accompany the units. Sixteen teachers and museum educators will participate in the training, evaluation and testing as the project is integratedinto the curriculum of twelve schools and four museums. The project is designed to be replicated in schools and science centers in different geographical locations nationally. The site for development and testing will be the Thames Science Center, a regional science museum in eastern Connecticut. The science center offers formal science enrichment programs and tours for students and teacher professional development programs throughout the region.
