Those studying the public understanding of science and risk perception have held it clear for long: the relation between information and judgment elaboration is not a linear one at all. Among the reasons behind it, on the one hand, data never are totally “bare” and culturally neutral; on the other hand, in formulating a judgment having some value, the analytic component intertwines – sometimes unpredictably – with the cultural history and the personal elaboration of anyone of us.
Earth & Sky (E&S) is a short-format science radio series airing daily on more than 1,000 commercial and public radio stations and translators in the U.S. as well as on satellite and Internet radio outlets. The series is also widely heard beyond U.S. borders. Produced by a small non-profit, Earth & Sky, Inc. of Austin, TX, the series is hosted by Deborah Byrd and Joel Block and consists of 90-second programs on a wide variety of topics mostly drawn from environmental sciences, earth sciences and astronomy but also including emerging technologies like nanotechnology. Over the previous three
EarthTalk, Inc. will develop and air 24 90-second shows per year for three years on the subject of nanotechnology on the Earth & Sky radio program. They will partner with Nano Science and Technology Institute (NSTI), Boston; Nanoscale Science and Technology Facility (CNF), Cornell University; and Center for Biological and Environmental Nanotechnology (CBEN), Houston to identify researchers, advisors and program ideas. Program categories will be Nano 101; Innovations that Could Change the World; Science or Science Fiction; Implications and Ideas; Nano and the Environment; and Listener Questions. The Earth & Sky program currently airs on 685 stations nationwide, making 323 million gross impressions each year; new shows will create some 64 million gross impressions. They will be supplemented by related material on Earth & Sky Online, which receives up to one million page views/month, and a composite of the nano programs onto CD mailed directly to 10,000 teachers yearly.

The Science Museum of Minnesota surveyed 16 museum visitors after they participated in the Exploring Measurement: Ruler Activity at NanoDays. This formative testing of the activity assessed the activity’s ability to convey the size of a nanometer, and that scientists need to use special tools when working at the nanoscale.
Visitors to the Science Museum of Minnesota provided feedback on the books, How Small Is Nano? and Is That Robot Real? in order to assess the books and their ability to impart knowledge of nanoscience. The visitors, 63 adults in all, read one of the books to the child or children accompanying them, then answered a series of questions about their experience including their interest in and enjoyment of the book they read, as well as the age appropriateness of the book. The report compares and contrasts the two books throughout.
This formative evaluation looks at the second version of a poster created to help visitors visualize the nanoscale structures in a butterfly wing. This version includes annotations to call out the different structures of the butterfly wing and reflects changes made to better align the illustration with scientific content.
A formative evaluation was conducted on Three Drops, an Immersive Digital Interactive (IDI), that allows visitors to interact with simulations of water at different size scales where different physical forces dominate. This evaluation revisits the exhibit after changes were made to address issues identified in the first series of formatives.
This report documents two formative evaluations on an interactive media piece that allows its users to zoom in from a human hand to an atom. This zoom uses a spiral to connote zooming and is a departure from a more conventional zoom in which each successive image is a magnification of a portion of the preceding image. Interview protocols are included in the appendix of this report.
The Science Museum of Minnesota surveyed 30 museum visitors after they used the Bump and Roll exhibit. This formative testing of the exhibit assessed the activity's ability to teach about nanoscale properties and scientists' uses of them.
The Science Museum of Minnesota surveyed 30 museum visitors after they used the Changing Colors exhibit. This formative testing of the exhibit assessed its ability to teach about nanoscale structures and the uses of nanophenomena to create new products.
