Mining and the Soudan Underground Mine Activities
Although designed to be used before or after a field trip to Soudan underground mine, these activities can be used in any classroom studying mining or the Iron Range. They are easily adaptable for grades K-12. Some are very tasty! Example lessons include: Birdseed mining, Cupcake core sampling, layer cake core drilling, and cookie mining. There are also some trivia and quiz links.

TimePieces - History Mystery (Primary Source Document Work)
Choose "Machines, Minerals & Migration". Aimed at grades 3-5, students must look at a collection of primary sources and decide what they have in common. Step one involves reviewing the evidence, looking at all of the sources and answer questions attached to each document. In step two, students build a case using the notes they have created in step one. The last step allows students to compare the conclusions they arrived at with those of other historians. Requires free registration.

Primary Source Documents - Mining
Part of a larger unit by the Minnesota Historical Society, this page has several primary source documents relating to the processes of mining. Several pictures of the tools of minig and documents relating to the cost and processes of mining. Clicking on each primary source opens a page with questions to answer and activities to do regarding the source.  Wonderful for OPVL. For all of the Hibbing units, click here.
