"ExNET — The Exploratorium Network for Exhibit-based Teaching"
ExNET — The Exploratorium Network for Exhibit-based Teaching Leveraging the Exploratorium Mission through a Network of Partner Museums Program Overview and Viewbook ExNET — The Exploratorium Network for Exhibit-based Teaching The Exploratorium Network for Exhibit-based Teaching (ExNET) is an international network of museums, science centers and one school district, who share Exploratorium exhibits and educational services. ExNET combines exhibit rentals, educational programs and museum professional development in one high quality program that offers a broad range of capacity-building opportunities for its partners. The eight current partners and science centers in ExNET rotate collections of Exploratorium exhibits annually, while drawing on the Exploratorium’s deep educational experience and resources to support their own efforts in their local communities. Transforming Science Education With its founding in 1969 the Exploratorium pioneered an entirely new conception of what a science museum could be. Like the experiments found in a laboratory or a so- called “tinkerer’s” workshop, the Exploratorium’s exhibits put the visitor right into the middle of the scientific process. Over the years, Exploratorium scientists, artists, and teachers have developed a fascinating collection of over 600 interactive exhibits representing a full array of scientific phenomena. Imaginative and engaging, the museum’s exhibits offer visitors of all ages and backgrounds a sense of fun and discovery while they explore real natural phenomena. The Exploratorium model for interactive, hands-on learning has transformed the world of science education. Today Exploratorium-originated exhibits are found in museums around the world. Partners have included Sony ExploraScience museums in Beijing and Tokyo, Ciencia Viva in Lisbon, Portugal, and Museo Interactivo Mirador in Santiago, Chile. While the Exploratorium has long shared its programs and expertise with other museums, the establishment of the Exploratorium Network for Exhibit-based Teaching (ExNET) in 1998 opened a new chapter in the museum’s growth and development. The Exploratorium, with its 36-year history of creative research and development, has unparalleled capacities in exhibit building, educational programming, and marketing. It also has a strong infrastructure for professional development: from the Teacher Institute and Institute for Inquiry, who work with teachers, to the Center for Informal Learning in Schools, that trains museum professionals and educational researchers. ExNET provides a tested and proven vehicle for using these capacities to advance science museums nationally and internationally. ExNET has the range and depth to meet the educational and organizational needs of a wide variety of museums and schools, from museums seeking to strengthen core programs or expand programmatic range, to schools looking to offer an interactive component to their science education. Candidates for ExNET partnership have identified audiences and good leadership, and are eager to strengthen their public offerings and to build their organizational capacities in the areas of education, marketing, and audience development. As part of a growing network of museums and schools throughout the country, the participants in ExNET – currently eight institutions – benefit from the high ExNET: The Exploratorium Network for Exhibit-Based Teaching quality of Exploratorium exhibits, supported by educational programs and opportunities for professional development and exchange. How ExNET Works ExNET partners commit to a specified contract period , during which they receive collections of exhibits sets for temporary exhibition, along with technical support, and a spectrum of educational services such as public education workshops, teacher institutes, professional development sessions, and capacity-building counsel. Three core elements comprise the successful approach of ExNET: exhibits, education, and network. We offer the program in contract lengths from one to three years, based on our partner’s needs. (1) Exhibits ExNET partners lease sets of Exploratorium exhibits focused around thematic areas in the sciences, mathematics, and human perception. Exhibit sets consist of up to four themes each, such as Electricity and Magnetism, Mathematics and Motion, Force and Structure, and Sound and Hearing. As of Summer 2006, ExNET offers single theme sets as well. Currently, full sets consist of 35-40 exhibits. Exhibits are selected for their educational and aesthetic value, popularity with visitors and students, and durability. The comprehensive strength of the Exploratorium’s core collections means that ExNET exhibits sets provide a solid curriculum for exhibit-based education. The exhibits connect readily to local, state, and national science and math education frameworks for classroom learning. Partner museums use the exhibits to support school programs, field trips, and teacher training. More information about ExNET exhibit sets can be found at http://www.exploratorium.edu/cmp/exnet/exhibits/group1/index.html. (2) Education Exploratorium teaching and exhibit development staff provide ExNET partner museums with up to 40 on-site training and consulting days over a three-year contract period. Training focuses on ways of using exhibits to support teacher training, hands-on tinkering programs for the general public, introducing Exploratorium-style artists’ residencies, or even methods of advertising, marketing, and fundraising for the new exhibits. Each site can choose the focus of its training days, and arrangements can be worked out with additional or less training included. ExNET partnerships also include exhibit installation and technical support so that exhibits require only routine maintenance from the partner sites. (3) Network Participating institutions and school districts become part of the ExNET peer network, where the sharing of information and expertise among the partners is facilitated by the Exploratorium and supported by extensive web-based resources. Participation in ExNET offers museums and schools solid educational resources and significant assistance with institutional advancement. ExNET partners have taken advantage of the prestige of association with the Exploratorium to enhance their institution’s marketing, audience development, community relations, and fundraising efforts. For smaller and start-up museums, this connection to the Exploratorium can provide a major step forward. For more established museums, ExNET’s capacity building and professional development provides the support to move to a higher and more ExNET: The Exploratorium Network for Exhibit-Based Teaching effective level of public service. ExNET offers school districts complementary informal resources that lead to more effective inquiry-based teaching. Through rotation of the exhibit sets among the partner museums, ExNET’s educational assets are leveraged across many institutions and communities. As exhibit sets rotate through participating institutions, ExNET partners develop knowledge, programming, experience, and understanding that can be shared with colleagues, further enriching and strengthening the educational collaboration. The Exploratorium and partner institutions regularly host network gatherings for sharing experiences, resources, and professional development. ExNET currently comprises the Exploratorium in San Francisco and eight partners: Discovery Center of Springfield Springfield Missouri Fort Worth Museum of Science and History Fort Worth Texas Montana State University Bozeman Montana G.WIZ, The Hands-On Science Museum Sarasota Florida Lousiana Tech University Ruston Louisiana Omniplex Oklahoma City Oklahoma Reuben H. Fleet Science Center San Diego California Worlds of Wonder Lodi California What’s Different? Dedicated to building the museum field and advancing a unique brand of learning, ExNET is the only program of its kind in museums and schools today. Here’s why: • A partnership created around the combination of exhibits and consulting differs significantly from traditional exhibit rental programs and traveling shows that typically provide only exhibits and interpretive materials. • State-of-the-art exhibits about science, mathematics, art, and natural phenomena provide the foundations for public programming, classroom curricula, and teacher professional development efforts that foster strong relationships with the schools. • Extended contract periods provide the necessary time to identify, explore, and develop the unique educational resources and abilities of the partner institutions. • ExNET builds partner institutions’ ability to serve as regional centers for teacher training and professional development in informal science education. Through the ExNET partnership, organizations such as the Fort Worth Museum of Science and Industry have become central hubs of thriving regional science center networks. • Through technical and capacity-building efforts, ExNET helps partner institutions form and strengthen relationships with their local business, education, and ExNET: The Exploratorium Network for Exhibit-Based Teaching governmental networks, thereby amplifying and sustaining the impact of the Exploratorium’s investment. The Future of ExNET Science centers, history museums, natural history museums, children’s museums, community museums, research centers, school districts and art centers are all strong candidates for network participation. While there is no single ideal candidate, there are some distinctive trends: Science center start-ups Each year, new science centers are planned and opened in the United States, supported by communities, schools, universities, and governmental agencies eager to improve science education and to offer young people and families the opportunity for creative engagement with learning and the world. When backed by professional leadership and financial administration, such start-up efforts are strong ExNET candidates, as the network can help to seed and shape new museum initiatives. ExNET can also provide a cost-effective way to "seed" a new science center program floor, by allowing a "try before you buy" approach for exhibit acquisition. Emerging regional leaders Whether established as a community science center and looking to take the next step, or ignited by a dynamic new director, organizations use ExNET as a means of efficiently expanding their exhibit resources and advancing staff knowledge and professionalism. The ExNET partnership is the chance to identify and foster the development of organizations that can become regional powerhouses in their own right. School districts and educational innovators A number of museums and science centers nationwide are forming close partnerships with their local school districts in an effort to improve classroom learning. While in major metropolitan areas the range of informal education offerings in museums and libraries is significant, smaller cities can be challenged by the capacities of their community museums. By adapting the model of its innovative partnership with the Los Angeles Unified School District, ExNET can offer these communities access to cutting-edge exhibits and educational resources that can help transform their museums into effective centers for teacher training, after school programs, and a wide range of other forms of exhibit- based experiences that serve as creative reinforcement for classroom learning.

ExNET: The Exploratorium Network for Exhibit-Based Teaching Example of an ExNET Exhibit Set - Rental Group 2 0003 - Aurora Aurora shows how reflections are created by both the shape of the light and the shape of the reflector. This reflector is a large curved sheet of brushed stainless steel. The ridges in the steel act like tiny mirrors, each reflecting an image. When the images from all the ridges add up, they blend into a single elongated image that looks like a ribbon of light. The many-colored tiles of the exhibit allow visitors to experiment with both the shape and color of the reflections. 0004 - Bells Bells consists of two metal plates which vibrate when they are stroked along their edges with a rosined bow. When each plate vibrates at a specific tone, sand on the top of the plate forms distinctive patterns. Sand bounces on the vibrating regions of the plate and collects in those areas where there is no vibration. The patterns are determined by the shape of the plate and the spot on the edge where the bow is applied, as well as the manner in which the bow is applied. 0175 - Blue Sky Blue Sky shows why the sky is blue. This is a phenomenon called “Rayleigh scattering”. A clear tube is mounted in front of a light source with the light shining into the end of the tube. The light scattered by the tube looks blue near the projector and gets progressively yellower further down the tube. A very orange “sun” emerges from the tube and is projected onto a screen on the side of the exhibit. A polarizing filter is attached to the exhibit table so the user can experiment with the polarized properties of scattered light. 0009 - Bridge Light Bridge Light lets visitors make interference patterns out of thin air. Two glass plates form a sandwich with a thin layer of air in between. By pressing on the top plate, bright and dark bands spread out in a swirling pattern. A bright band appears wherever light waves reflecting from the back and front surface of the air film between the plates coincide; a dark band appears where the light waves cancel each other out. The light source is a sodium vapor lamp and produces a pure yellow light of similar wavelengths, making visible the interference patterns that are not visible in white light, with its mixture of different wavelengths. The exhibit also illustrates absorption and reflection. Several brightly colored cards look dull under the sodium light, but appear in full color under white light. EXPLORATORIUM EXHIBIT SERVICES The name in quality exhibits since 1969 ExNET Exhibits - Rental Group 2 0125 - Chaotic Pendulum Chaotic Pendulum contains a deceptively simple set of pendulums in a steel and Plexiglas case. A central, T-shaped bar supports three bearing-mounted bars from its ends. The “T” is itself bearing mounted at the intersection of the upright and the cross arm. The visitor gives an initial twist to the pendulums with a protruding knob. Intuition says that the resulting motion of this system should be, if not simple, at least predictable. Intuition, however, does not work with this device since its motion is chaotic, extremely complicated and long-lived. 0230 - Circling Wave Umbrella A spinning disc of fabric undulates in complex ways and organizes itself into a pattern of circling waves. The pattern of waves is influenced by the surrounding air currents as well as by visitors who can change the speed of rotation by adjusting a knob. 0353 - Cold Metal The temperature sensitive nerve endings in your skin must detect the difference between your body temperature and your skin temperature. When your skin cools down, the temperature sensitive nerves tell you that the object that you are touching is cold. The metal, the wood and the styrofoam at this exhibit are all the same temperature and are colder than your hand. But, because they do not carry the heat away from your hand at the same rate, they do not feel equally cold. 0015 - Color Removal In Color Removal, a light shines through a prism and is spread out into a spectrum, while the remaining light goes directly to a white screen. By placing filters in the light path, visitors can observe the unseparated mixture of all the colors in the light that hits the screen. The constituent colors in the light that goes through the prism are also visible. Each filter removes (absorbs) some of the colors from the beam of light. The spectrum shows what colors are removed and what remain. The filters are made of organic dyes which absorb some of the wavelengths of visible light. EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0017 - Colored Shadows The Colored Shadows Wall is a discovery of the colors hidden in white light. Red, green and blue spotlights shine on a wall. The wall is white because red, blue and green light combine to make white light. These colors are often called the additive primary colors. As you walk between the lights and the wall, your body casts three different shadows. Wherever a shadow blocks one color of light, the other two colors combine to produce a new complementary color. By standing close enough to the wall, six different colors can be created, as well as black and white. 0024 - Diffraction In Diffraction, a small bright light is mounted behind a hole in a darkened wall. When looking at the light, it seems to twinkle. This effect is caused by the bending of light in the eye and its lens. This same diffraction effect is observable in other objects by using the various props at the exhibit. A diffraction grating bends the light enough to produce rainbow effects. There are also some common objects, like a piece of screen, which afford a view of the diffraction patterns caused when light bends around edges. 0253 - Echo Tube The Echo Tube is a very long tube sloping up almost to the roof of the Exploratorium. When the visitor claps his hands at the end near the floor, an echo is heard about 1/5 second later. The echo has a strange sound unlike the original clap (and much like the ricochet heard in old cowboy movies) due to the many different paths that the sound takes inside the tube. A rough estimate of the speed of sound can be made by timing the echo of the clap. You can also listen to the echo of your voice as it traverses the length of the tube. This makes speaking difficult due to the delay between saying a word and hearing it. 0105 - Energy vs Power Energy vs Power distinguishes between the two concepts embodied in the name. Physicists have specific definitions for “energy” and “power” even though these words are often used interchangeably. Energy is the ability to do work, while power is the rate at which work is done. In this exhibit, a hand generator is used to create a charge which is stored in large capacitors; the capacitors hold a given amount of energy. The capacitors can then be discharged through one of several different light bulbs that vary in resistance. The energy is consumed at different rates and hence the bulbs have different power ratings (wattage). EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0179 - Gaussian Melody Three steel balls fall through an array of pins to produce a random melody. The pin array emulates a Gaussian distribution demonstration where numerous balls are fed at the top of a triangular array of pins, then bounce through the pins to become distributed along the bottom with a Gaussian profile. This distribution is not obvious with just three balls, however the pins are set in at different depths which in conjunction with the erratic path of the balls produce a random melody. The array and sound box are mounted on a pivot to move the balls back to the top of the array. This exhibt was created by MacArthur Foundation Genius Award recipient Ned Kahn Natural finshed wood with hard black anodized bowl. Powder coated steel stand 0329 - Giant Guitar String A piece of rope 100 feet long stretches horizontally between two supports. By pulling on the rope at one end, visitors can make waves in the rope. Adjusting the rope tension and varying the agitation frequency creates different wave patterns, revealing resonances, nodes, antinodes, and 180 degree phase shifts as the waves reflect off the fixed end of the rope. 0224 - Heat Pump / Hand Crank Turning the crank on the Heat Pump exhibit pumps heat from one copper coil to another. Visitors crank a small refrigerator compressor and compare the temperature of the two coils, one hooked to the high pressure output of the compressor, the other to the low pressure input. As more work is done, the high pressure coil becomes warm and the low pressure coil becomes cold. Leakage from the high pressure side to the low pressure side can be regulated with a valve. 0158 - Lariat Chain This whirling loop of chain responds to touch with eerily lifelike waves that seem to hover in midair. The motion of the chain itself causes the unusual effect: When waves travel in the direction opposite the direction of the moving chain, they seem to move very slowly, or even stand still. EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0036 - Light Island At Light Island, visitors can play and experiment with various aspects of optics. From a 200-watt light source in the center of the table, beams of white, red, green and blue light created by color filters, radiate out onto the table. Mirrors, lenses, prisms and filters can be placed in the path of these beams to reflect, bend or mix the light in many ways. 0088 - Listening Vessels Listening Vessels consists of two large parabolic reflectors set at least 50 feet apart which act as mirrors to reflect sound from one to the other. Two people sit opposite each other at approximately the focal point for each reflector, so that the sound coming from each reflector is focused at this point, allowing each visitor to clearly hear the other’s voice, even at a very low decibel level in spite of the distance separating the vessels. 0089 - Low Frequency Light An incandescent lamp filament is focused on a sheet of temperature sensitive, liquid crystal. The liquid crystal sheet indicates that more energy is present below the visible spectrum. Filters that swing into the light path allow the visitor to experiment with the light. The liquid crystal shipped with the exhibit has a sensitive temperature range of 25-30°C. This suits most environments well. If the exhibit is used in a very warm environment, a 30-35°C liquid crystal may be needed instead. 0222 - Molecular Buffeting Model Molecular Buffeting Model illustrates Brownian Motion as described in Molecular Buffeting Real. The hotter a substance the more energy there is in the motion of the molecules. In this exhibit the ball bearings represent the molecules and the rotating bars serve to "heat" and/or "cool" the ball bearings. The faster their average motion, the higher the "temperature." As the large white object is buffeted on all sides, its movement parallels that of a very tiny particle being struck on all sides by small numbers of invisible molecules. This is the Brownian Motion that can be seen through a microscope. EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0223 - Molecular Buffeting Real Grains of pollen suspended in water performing a strange erratic dance that never stopped was a fact noticed by English botanist Robert Brown in 1827 while peering into his microscope. Brownian motion remained a mystery until it was realized that the erratic dancing behavior of small particles could be explained by the molecular theory of matter. A very tiny particle that is being struck on all sides by small numbers of invisible molecules can temporarily get out of balance; the invisible molecules will then give the particle an extra push in one direction which produces the motion that can be seen through a microscope. 0399 - Oscylinder Scope The Oscylinder Scope is an interactive artwork/exhibit which explores the nature of sound by directly translating the vibration pattern of musical strings into visible waves. You first start a large horizontal cylinder rolling by spinning it with your left hand. You use your other hand to strum the three musical strings. White lines engraved into the black cylinder scan the vibrating strings so that they appear as wavy lines. This startling phenomenon is at the heart of the Oscylinder Scope. The displayed wave form looks and acts like the trace on an electric oscilloscope. Each of the three musical strings displays a different wave pattern according to its frequency. You use a foot pedal to change the sound you hear, as well as the shape of the wave you see. 0096 - Resonant Pendulum The visitor swings a small magnet onto a steel collar attached to a heavy pendulum hung from the ceiling. Because of the weak magnet, the visitor learns that only by pulling in time with the swing of the pendulum (in resonance), can the pendulum be moved. Two magnets are tied to the fence at 90 degrees to each other so the users, if they cooperate, can alter the pattern in which the pendulum swings (circle, ellipse, line, etc.). Pendulum, magnet assemblies and pipe rail fence are included. Pendulum need to be hung from a ceiling beam that can support 140 kg. 0052 - Resonant Rings Resonant Rings consists of circular steel bands of various diameters that are mounted on a plate which has been attached to a loudspeaker. By adjusting the frequency of the sound from an oscillator to the speaker, a graphic illustration of harmonic resonance can be seen in the rings as they vibrate at various frequencies and in different modes. The frequency of the speaker can be read directly on a digital counter. Exciter levers are provided for two of the rings so they may be struck lightly and their “natural frequency” observed, or their motions dampened. EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0053 - Resonator Resonator demonstrates that objects can be made to vibrate energetically (resonate) over a range of frequencies. Two flexible steel bars are attached to a motor-driven vibrating table. As the table jiggles back and forth, it sends waves along the bars which reflect off the upper ends of the bars and return to the table. If the motion of the returning wave is in phase with the table’s vibrations, it will be reinforced at the table and sent back up the bar, eventually forming a standing wave where the bar vibrates in a large stationary pattern. The frequency of the table’s vibration can be varied or the exhibit allowed to go through a programmed sequence. Price includes Graphics, technical manual and choice of paint paint and laminate color . 0338 - Skillets Four skillets can be placed on heating elements, revealing the different heat transfer characteristics of cast iron, aluminum, stainless steel, and copper clad stainless steel. Temperature sensitive liquid crystal film is glued to the inside of each skillet. The film reveals how heat spreads through the material by changing color as the temperature changes. A section is cut from each skillet to show the material that each pan is made of. Overall Dimensions - .1.07m w x 1.52m h x .66m d Weight - 45 kg 0060 - Soap Bubbles Tray Soap Bubbles is a large tray filled with a special soap-solution and equipped with metal hoops of various sizes. With these hoops, visitors can make huge soap bubbles, occasionally big enough to fit over an entire person. Dimensions: 1.68m w x .79m h x 1.75m d 91kg Locking lower cabinet with wheeled storage cart. Drain is located inside. Color choice for laminated cabinet and metal frame. Includes stand mounted graphics (available in bi-lingual), technical manual, 25 0061 - Soap Film Painting Soap Film Painting allows visitors to make a six-foot-by-six-foot vertical soap film. Within this film, visitors can observe colors created by the interference of reflected light waves and the wave patterns that form in a vibrating medium. By gently shaking the frame or blowing on the film, the changing colors and waves are enhanced. Price in cludes mounted graphics, technical manual and warranty. Choice of paint and laminate color included. Dimensions - 1.83m w x 2.84m h x .61m d Weight - 114kg Production time - 9 to 12 weeks from receipt of 50% deposit. EXPLORATORIUM EXHIBIT SERVICES ExNET Exhibits - Rental Group 2 0064 - Spectra Spectra allows visitors to play detective, examining the “fingerprints” of elements in the form of spectra. The exhibit provides gas-filled tubes of Argon, Mercury vapor, Neon, Nitrogen, Helium and Xenon. As the exhibit’s pointer is turned, a different element lights up. The emission spectra of the various gases may be examined by selecting a particular gas and viewing it through a diffraction grating. 0811 - Tune Blocks Developed by a cognitive psychology professor at MIT, Tune Blocks breaks music into various groups of notes- testing the theory that the relationship of a series of notes to one another creates a pattern easier to learn than any one single note. Use the preconfigured tune blocks or create your own to compose an original melody. 0071 - Vibrating String In Vibrating String, an electric vibrator tugs a string 120 times per second. The string can resonate in different standing wave patterns depending on the tension of the string. By tightening or loosening the string, visitors can change its fundamental resonant frequency and the number of waves they see. 0072 - Visible Effects of the Invisible Visible Effects of the Invisible graphically demonstrates resonant frequencies. A horizontal, clear glass tube is partially with clear fluid. Sound generated by a speaker housed at one end of the tube causes the air in the tube to vibrate and geysers appear in the fluid where the motion of air is greatest. The geysers are generated at various sections of the tube by the adjusting the resonant frequency of the speaker which causes pressure differentials.
