Chemistry in Museums

“Murder and mayhem and whatnot is much more exciting than test tubes and Erlenmeyer flasks.”
–Paul Bryan

Speakers in this session discussed chemistry in different types of science museums, which have served as popular venues for informal learning for many years.1 The speakers included Sapna Batish from the National Academies’ Marion Koshland Science Museum, in Washington, D.C.; Susanne Rehn, via webcast, from the Deutsches Museum, in Berlin, Germany; Shelley Geehr from the Chemical Heritage Foundation, in Philadelphia, Pennsylvania; and Peter Yancone from the Maryland Science Center, in Baltimore, Maryland.

CHEMISTRY AT THE KOSHLAND SCIENCE MUSEUM

Sapna Batish provided a brief history of the National Academies’ Marion Koshland Science Museum (Figure 5-1). The Koshland opened in April 2004 and prides itself on being a science museum for teens, unlike many museums in the United States that are focused on an elementary school audience. All of the Koshland exhibit content is based on studies conducted by the National Research Council (NRC). An exhibit topic is chosen based on there being a major body of work by the NRC to support it, if it is continuing to be researched, and if it has significant relevance to society.

The Koshland is considered a hands-on museum. Rather than having artifacts, the museum focuses on using digital interactive equipment to convey science to its audience (Figure 5-2). The museum is also unique in that it shows the confluence of science and policy, given that its exhibits are based on NRC studies about scientific topics that are relevant to society. In addition to having a general audience, the museum also works with middle school and high school students. It offers free field trips and transportation to middle school and high school students in the Washington, D.C., area. Batish added, “We like to connect current science with tangible, real-life scenarios for students and teachers. All materials have been designed by former teachers and are field-tested with students.”

Koshland has three main exhibits. The first is called the Wonders of Science, which includes satellite imagery, population density, and energy use over a 10-year period, as well as the human cell. There is also an exhibit developed at Harvard Medical School featured in the museum, as well as an interactive exhibition that looks at the origins and expansions of the earth and the universe.

The second exhibit looks at emerging challenges of infectious diseases, such as malaria, AIDS, and tuberculosis, in an interactive manner. Batish explained, “In the one on tuberculosis, visitors get to be doctors. They get to choose a patient,

Based on the success of that exhibit, the museum is in the process of developing a new climate gallery. It is going to be based on two recent NRC studies—America’s Energy Future and America’s Climate Choices. The climate gallery will include topics such as climate science, climate impacts, mitigation, and adaptation to climate change. They will be much more focused on decision making and on advanced decision-making tools. Batish noted that it is challenging to help the public understand something as vague and ambiguous as climate change through a hands-on science activity. She said that the FIGURE 5-2 The Koshland museum focuses on using digital inter- active equipment to convey science to its audience.

It has been there since the museum opened and displays evidence that humans are causing recent climate change. She added, “It starts off by asking, Has the climate changed, what are its causes, how might it change in the future, what are the consequences, and how can science be used to inform our responses to climate change?” Chemistry is offered through all core areas of the Kosh- land, which include museum exhibits, field trips, hands-on science in the museum, community outreach efforts, public programs, and its website. As she heard many of the speakers say, Batish added, “Chemistry is just an inherent part of every aspect of life. We don’t have to talk about chemistry from the perspective of an atom or a molecule at the museum. It becomes apparent to visitors that the basic fundamentals of what we are talking about are based on chemistry.” For example, there is an exhibit that shows images of ice cores. It helps visitors understand how ice cores can be used to measure the temperature of the earth 500,000 to 800,000 years ago. It involves using a ratio of oxygen isotopes from air bubbles trapped in the ice cores to infer temperature. “Then, coming back to the present, we talk about changing concentration of greenhouse gases and what that means in terms of our current and future climate,” Batish added. One of the most popular exhibits is one that focuses on decision making. The Koshland found that visitors really enjoy this exhibit because they get to consider the environ- FIGURE 5-3 Consider the alternatives.

One activity was developed by a chemistry student who was finishing up her Ph.D. in chemis- try at Northwestern. It shows museum visitors how changing chemistry levels can lead to ocean acidification. The activity also helps visitors understand how ocean acidification will impact calcareous plankton, coral reefs, and other marine ecosystems. The museum is involved in many festivals around the city. One in particular is the Arts on Foot Festival. It takes place near the Verizon Center every September. Batish showed a picture of one of the fellows engaging in an exercise that simulates the spread of infectious disease, using simple ingredients to represent bacteria, vaccines, and antibiotics. “We help them to understand how quickly FIGURE 5-4 The Deutsches Museum, which opened its doors on disease can spread and what we can do to combat that,” the Museum Island in 1925, is the largest science and technology she explained. museum in Germany, with approximately 1.4 million visitors an- The Koshland also offers public programs.

There are many people around at that time, strolling around, looking at art, getting something to eat, and having drinks. CHF stays open late too and offers activities to attract visitors to the museum. Activities include making molecular origami, batteries out of lemons, and sun prints. Gehr noted, “It is amazing, the number of young people and adults who come in. They sit down, they will work on a small project for 20 to 30 minutes, and while they are doing this, we have someone walking around in a very casual way, talking about the science or the chemistry of what they are doing.” She said that last December they made papier maché ornaments and had a staff member who is a chemist talk about starch chemistry. People had to leave the ornaments behind because they were too wet, but they came back the following Monday to get them. “So it tells you that they had a good time, they valued it,” said Geehr. In addition to the museum and activities, CHF also has a magazine, which Geehr described as its touchstone. “It has been around since the beginning. We use it to tell a variety of stories about the history of chemistry. We get tons of letters, tons of people coming up to us saying we love your magazine, particularly teachers. A lot of teachers find ways to use these features in their classroom.” The magazine staff also works closely with CHF web staff to expand the communication of FIGURE 5-7 Everyday objects.

CHF has additional features on the web, such as its weekly podcast called Distillations.4 Geehr said that CHF has been producing the award-winning Distillations program since 2007 (the New York Festivals gave CHF three bronze medals for the podcasts in 2009). CHF also has three blogs, which she said all have very distinct voices. One is for the CHF schol- arly community; one is the CHF president’s blog, where he talks about a variety of topics that interest him; and the third is called “The Center,” which highlights research and other activities by scholars in the CHF Center for Contemporary History and Policy. Gehr noted that CHF is also getting involved in social media, such as Facebook, Flickr, Twitter, and YouTube. She FIGURE 5-8 Periodic Table of Cupcakes.
