Cut a pound cake in half, and what do you have? It is still pound cake, but in two pieces instead of one. What if you keep slicing and dicing the pound cake all the way down to single crumbs? No matter how many times the pound cake is cut, it's still pound cake.
What does pound cake have to do with the universe? Just like the chemical elements that are the building blocks for all the matter in the universe, pound cake retains its identity no matter how many times it's divided. Pound cake also plays a key role in an activity that's part of Afterschool Universe, a NASA-sponsored astronomy program for middle school students.
Afterschool Universe is targeted for settings outside the normal school day. The program consists of 12 standalone sessions in which students explore basic astronomy concepts.
"We saw a need for the program because existing astronomy education materials covering such topics were mostly aimed at high school students. Middle school students were fascinated by these concepts but had few options to learn more about them," said Anita Krishnamurthi, the program's project lead. "There's a great potential to engage students and adults in astronomy in the afterschool setting."
Each session usually begins with a brief introductory discussion facilitated by the program leader, followed by a hands-on activity in which students participate individually or in groups. A session typically runs about 45-60 minutes and culminates with a wrap-up discussion focusing on what was learned through the activity.
In most cases, program leaders must undergo training before they can run the program or train others to do so. Information sessions and training workshops are offered at various locations across the country, including at the NASA Goddard Space Flight Center in Greenbelt, Md.
Upon completion of training, program leaders receive a NASA certificate, a comprehensive program manual, downloadable files, worksheets and evaluation forms, posters, and a kit of materials that are only available from specialized suppliers. Program leaders are responsible for obtaining the basic materials needed to implement the program. NASA encourages leaders to partner with a local scientist.
The manual provides background information and detailed descriptions of how to conduct each session, including listings of objectives, concepts addressed and materials needed. No activities require use of a computer, though the manual gives suggestions for optional Web-based activities.
Afterschool Universe, funded entirely by several grants for NASA's Science Mission Directorate including the Chandra Mission, was developed by the education and public outreach team in the Astrophysics Science Division at NASA's Goddard Space Flight Center in Greenbelt, Md.
