Karst Rock Detective

For this lab activity, students will be asked to bring an Ozark rock from home or nearby. They will conduct basic tests and use a simple rock lab chart to identify four common Ozark rocks: limestone, dolomite, chert, and sandstone. Students will graph the lab results and may draw conclusions about the makeup of surface rocks in the Ozarks.
