National Digital Science Library

The NSF issued a press release to announce the creation of the National Digital Science Library (NDSL), “an online digital library for science, technology, engineering and mathematics education for all ages.” The press release contains brief descriptions and links for just a few of the collections available through the NDSL. I have posted these descriptions below.

I plan to spend some time exploring this resource, and will most likely mention some of my findings in future postings to “Citizen Scientist”. However, I encourage you to go forth and explore on your own! Have fun!

BONES OF CONTENTION: HUMANS AND PRIMATESThe eSkeletons project at The University of Texas at Austin lets students and teachers view and compare the bones of a human, gorilla, baboon as well as other species and gather information about them from the Texas anthropology department’s osteology database. In addition to high-quality, close-up images of bones and labels for each bone’s key anatomical features, the eSkeletons site lets visitors examine the bones through high-resolution 3-D animations and as interactive virtual reality objects. The eSkeletons site will soon be making bone data available in a format from which visitors can create 3-D replicas of the bones (with appropriate equipment).”

WIRED FOR ANIMAL SOUNDS — The sounds of Psittacidae, the parrot family, are among the thousands of animals whose sounds have been recorded and stored in the Macaulay Library at the Cornell Lab of Ornithology. The Macaulay Library houses the world’s largest collection of video and sound recordings of animal behavior, and a new NSDL project is supporting the library in its efforts to make its archive available online for research, education and conservation uses. The Macaulay Library currently holds over 160,000 sound recordings from not only 136 species of hawks and eagles, more than 40 species of hummingbirds and 180 species of woodpeckers (including the extinct ivory-billed woodpecker) and other birds, but also many other animal groups such as whales and dolphins (through a $2 million grant from the Office of Naval Research), insects, New World mammals and frogs. In addition, the library will soon archive a diverse collection of the communication signals used by electric fish. The Macaulay Library is building a parallel library of videos of animal behavior and currently has material on over 2,500 species of birds. All of this, along with annotations on content, will be made available through the new NSDL portal to the Macaulay Library of Natural Sounds.”

MECHANICAL MODELS IN MOTION — Cornell University holds the world’s most complete collection of model machines designed by German engineering professor Franz Reuleaux (1829-1905). Reuleaux, the founder of modern kinematics and a forerunner of modern design theory of machines, created the machines to teach kinematic principles. The Kinematic Models for Design Digital Library (K-MODDL) will be a collection of digital images, movies and interactive models centered around these 220 rare 19th century mechanical models. Over time, the project intends to have other models from all over the world added virtually to the collection. Simulations of the models’ movements, related fulltext documents and sample classroom teaching modules are planned for the collection. The K-MODDL team of librarians and mechanical engineering and mathematics professors is also developing a method that allows the machines to be “printed out” into working plastic models-a preview of future digital libraries that may allow users to access a hand-held replica of cataloged objects.”

EXPLORATORIUM ONLINE — San Francisco’s Exploratorium, the hands on science museum for all ages established in 1969, is developing exploratorium Online, a digital collection of teacher-tested resources from the museum’s 650 interactive exhibits. These exhibits cover topics ranging from the science of eggs to weight on other planets The NSDL collection will enhance the information on the Exploratorium’s extensive Web site (established in 1993) by providing access in a uniform, searchable database coordinated with curricular standards. The project is also creating guidelines for cataloging digital exhibit-based science resources that capture the unique museum quality and maximize the teaching value of Exploratorium digital assets.”

A CENTURY OF OCEAN EXPLORATION — Not everyone can ride a research vessel through stormy seas from New Zealand to Samoa to map the ocean floor. To bring the human side of oceanography to life for students and others, the Scripps Institution of Oceanography (SIO), the San Diego Supercomputer Center and the University of California, San Diego, Libraries are creating SIO Explorer, an oceanography digital library that combines materials from the SIO Library Archives, data from the SIO Geologic Data Center, published research papers and historic documents from SIO’s 100 years of ocean-going voyages. Each modern cruise results in nearly a thousand digital objects. SIO is one of four key institutions that pieced together the concepts of plate tectonics in the 1960s, and SIO Explorer will be a data-oriented collection for plate tectonics education. Items in the collection are being linked to historic and modern marine geological and geophysical data via information technology tools that “bridge the gap” between science data archives and libraries.”

THE GLOBAL CULTURES OF MATHEMATICS — The Yup’ik people of Alaska count in a number system based on 20s, as did the Mayans of Central America. The Chuukese people of Micronesia have different words for counting objects depending on whether the objects are flat, long, solid or layered. The ancient Incans counted with quipus, strings with knots tied in them. Ethnomathematics is the study of how every culture’s unique approach to mathematics is reflected in its language and daily life, and the Ethnomathematics Digital Library is a collection of articles describing the mathematics of cultures from the Aborigines in Australia to the Shona people of Zimbabwe. The EDL, being created by a network of institutions led by Pacific Resources for Education and Learning, has the potential to foster the creation of classroom materials that acknowledge and build on these cultural foundations.”

FROM FRANKLIN’S STOVE TO A SCANNING ELECTRON MICROSCOPE –The Innovation Curriculum Online Network (ICON) provides a central source that helps teachers find Web-based classroom activities dealing with technology and innovation and its impact on the human built world, history, and society. The activities, searchable by topic and by grade level, range from a kindergarten connect-the-dots puzzle of Ben Franklin’s stove to a virtual scanning electron microscope for a high school science class. The International Technology Education Association and The Eisenhower National Clearinghouse have created ICON for K-12 teachers and college and university faculty to find information and classroom activities that increase students’ technological literacy.”
