  1. Mineralogy 4th grade minerals experiment Jim Hower, hower@caer.uky.edu University of Kentucky, Center for Applied Energy Research 2540 Research Park Dr., Lexington, KY 40511 859-257-0261

  2. Overview • Experiment Objectives • Materials • Procedure • General Observations and Helpful Hints • Resources

  3. Experiment Objective To learn the physical features we can use to identify minerals.

  4. Materials Needed Mineral kits from Wards: Hardness Fracture Luster Streak Also: Limestone and dilute HCl

  5. Procedure Start by asking students what features they would use to tell one mineral from another: Examples might be color, mass, fracture, taste (but discourage them from tasting minerals), etc.

  6. Procedure Set up a number of stations and have students rotate through (maybe 10 min each station) This way the size of the groups is small and everyone has a chance to observe and ask questions.

  7. Helpful Hints & Observations Testing limestone and other rocks with HCl has proven to be a popular station. Have non-limestone rocks available and have students guess which ones will react. They will want to put the HCl on their skin, discourage this.

  8. Resources for Minerals • State Geological Surveys • Ward's Scientific www.wardsci.com • Internet sites such as www.webmineral.com • (excellent resource and good links to everywhere else in the mineral world) • Local rock and mineral trade shows
