Rocks and Minerals: Compare Rocks with their Streak Color Mineral Analysis Lab

In this activity, kids will act like geologists as they streak test different minerals. Some minerals have streaks that are like their color, but many do not. Pyrite, or fool’s gold, gives a dark olive green streak, and fluorite which is dark purple leaves a white streak. Most times, the streak test is helpful in identifying the mineral. You'll need various mineral samples plus easy-to-find materials.
