Breaking Barriers: A Microscopic World
This collection includes objects and resources related to medicine in the 19th century. During this time, an incredibly huge scientific barrier was broken when scientists discovered bacteria and viruses, which could not be seen with the naked eye, could cause disease. This board will examine the scientific barrier that was broken into the microscopic world and how medicine and modern science changed due to such discoveries. Additional resources on this topic can be found by visiting the National Museum of American History's online exhibitions at AmericanHistory.si.edu and History Explorer at HistoryExplorer.si.edu.
Each National History Day collection from the National Museum of American History includes selected resources to support NHD projects under the 2020 theme - Breaking Barriers. This collection is by no means comprehensive, but should be used as a place of inspiration for new projects or source of additional information for ones already in the works. For grades 6-8.
