The Bottom Line on Video Resources - Here on Top!
Bottom Line: Short instructional videos may be useful to students as a pre-lab assignment, as an in-lab guide to tests and procedures, as an out-of-lab review, etc. YouTube serves to all devices.

Uncertainty or Failure of Test Results
Importance of Test Procedure
Identifying a mineral by name requires making observations to determine a sample's physical and chemical properties.
Physical samples may be tested with relatively inexpensive and common materials, such as a porcelain tile, a piece of glass, a magnet, a flashlight, etc.
Test results are subject in part to correctly conducting a test procedure. For example, if an insufficient amount of vertical force is used to test a sample for its relative hardness on a glass plate, no scratch may develop and the test result will be negative, even if the mineral is in fact harder than a glass plate.
These instructional videos include narration that focuses on procedural details necessary for preventing a failure of observation.
