Hot Springs National Park with its hot springs, natural areas and historic use of the springs for medicine and recreation can provide extensions for your classroom materials. Park podcasts are now posted on iTunesU, Arkansas Department of Education section. These include short segments about the hot spring water as well as the bathhouses and trails. From this link, navigate to the history section on the categories menu on the right, then select Hot Springs National Park podcasts. Not all of the podcasts are history, but that will get you to the entire list.
