Four Unlabeled Minerals

Test results for four unlabeled minerals, each tested the same five ways. WHAT EACH MINERAL DID Mineral A: scratched by a fingernail, pearly shine, white streak, not pulled by a magnet, no fizz Mineral B: scratches glass, glassy shine, no streak, not pulled by a magnet, no fizz Mineral C: not scratched by a coin, metallic shine, black streak, pulled by a magnet, no fizz Mineral D: scratched by a coin but not a fingernail, glassy shine, white streak, not pulled by a magnet, fizzes with vinegar Tests: scratch, shine, streak on a rough white tile, magnet, a drop of vinegar.

  1. 1. Why was every mineral given the same five tests?
  2. 2. Which mineral was pulled by a magnet?
  3. 3. Which minerals left a white streak?
  4. 4. Which mineral scratched glass?
2.A mineral scratches glass. What does that tell you?
  • A.It is softer than glass
  • B.It is made of glass
  • C.It is harder than glass
3.What does the streak test show?
  • A.How shiny the mineral is
  • B.How heavy the mineral is
  • C.The color of the powder a mineral leaves when rubbed on a rough white tile
4.A mineral fizzes when a drop of vinegar is put on it. What does that show?
  • A.It is melting
  • B.It is magnetic
  • C.It reacts with the vinegar, which is a property you can test
5.Two minerals give the same result in every test you ran. What should you do?
  • A.Decide they are different
  • B.Try another test, or consider that they may be the same mineral
  • C.Stop testing
6.Four gray minerals are tested and only one is pulled by a magnet. What is that test good for?
  • A.Telling the other three apart
  • B.Finding how hard they are
  • C.Picking that one out from the rest
7.Why is a mineral's streak better evidence than its color?
  • A.A mineral's color can vary, but its streak usually stays the same
  • B.Color cannot be seen
