Education - Wooly Magma
Wooly Magma is a felting project that teaches participants (best for ages ten and up) about the structure of the Earth. The felt model is constructed with colorful wool rovings (wool that has been washed, carded, and processed into long strips), each correlating to a layer of the Earth that is named and discussed during the crafting process. A small psychedelic rubber ball is used to represent the Earth's inner core around which the wool is wrapped to create a solid sphere of felt. At the end of the felting, the balls are cut open to reveal a geode-like layering.
This project was designed by ESRL/Global Systems Division's Annie Reiser (a non-scientist) as her contribution to a past science festival held at NOAA in Boulder. The project, which supports NOAA's cross-cutting environmental literacy program, has since been offered to groups for Science Fairs, Bring Your Child to Work Days, Earth Day activities, and school groups at the Boulder Labs, as well as off-site demos upon request.
