    1. Define the term native metal.
      b. Define the term malleable.
      c. Define the term metallurgy.
      d. Define the term alloy.
      e.
      Name two nonferrous alloys used by pre-Iron Age metalworkers. Name, and name the metals that are combined to form these alloys.
    2. f. Explain the term ferrous, and name Name three ferrous alloys used by modern metalworkers.
    3. g. Describe how to work–harden a metal.
    4. h. Describe how to anneal a non-ferrous and a ferrous metal.
  3. Do the following:
    1. Work-harden a piece of 26- or 28-gauge sheet brass or sheet copper. Put a 45-degree bend in a small piece of 26- or 28-gauge sheet brass or sheet copper the metal, then heavily peen the area along the bend line to work-harden it. Note the amount of effort that is required to overcome the yield point in this unworked piece of metal.
    2. Work-harden another piece of the same sheet brass or sheet copper. and then put a 45-degree bend in it. Note the amount of effort that is required to overcome the yield point.
      c.
      Soften the same bent, work hardened piece from requirement 3a by annealing it and then try to remove the 45–degree bend. Note the amount of effort that is required to overcome the yield point.
    3. Make a temper color index from a flat piece of steel. Using hand tools, make and temper a center punch of medium-carbon or high-carbon steel.
      d. Join two small pieces of scrap metal using a hammered rivet. Repeat the process using a pop rivet.
      e. Using a flatlock seam, join two pieces of scrap metal together with either lead-free solder or silver solder.
