This activity offers a fantastic lab experience to both students that have materials available or that may not. What makes this lab so special is that the student body can be diverse in ability level and age. In addition, it is formatted so that a teacher has a wide range of discretion as to what information is given to students and what is not. You won't regret adding this to your mineral and geology library. Please see the preview!
Students will investigate the hardness of talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and diamond. They will do so using the famous scratch test and provided images to determine an acceptable range of hardness.
This has been used as a pre-class, lab/activity, study guide, review, and assessment. This is an effective teaching tool one on one, in small groups, and as a class when using a Smart Board/Promethean Board/Projection.
