Students create a mineral person from the different mineral shapes.

The objective of this lesson is to learn that minerals have many shapes. Students will create a mineral person and can then tell stories about their mineral person.

The worksheet lists examples of minerals that show the illustrated crystal shapes. Sphalerite is zinc sulfide, which is an important ore of zinc. Gypsum is calcium sulfate which is used in the production of wall board, plaster of Paris, and fertilizer. Quartz, which is silicon dioxide is one of the most widely used minerals with such applications as glass making, jewelry, porcelain, and sand paper. Pyrite is iron sulfide and is commonly referred to as "fool's gold." Pyrite is mined for its sulfur and in some cases for its iron. Galena is lead sulfide and is an important source for lead ore. Orthoclase feldspar is composed of potassium, aluminum, silicon, and oxygen and is used in the manufacture of porcelain.

  1. Have the students look at the minerals shapes page on their worksheet. Tell the students some of the above background information about each of them. Remind your class that minerals grow in many different shapes.
  2. Ask students to color and cut out the mineral shapes. Give them suggestions for colors. Sphalerite is usually a yellowish-brown color. Gypsum is white to clear. Quartz can be just about any color, from purple to striped. Pyrite is gold colored. Galena is silver or gray. Orthoclase is usually pinkish orange.
  3. Ask the students to arrange their cutouts into the shapes of either a man or a woman, or any other organism of their choosing.
  4. Allow the students time to share their stories about their mineral people. This lab can be extended into a writing lesson by having them write a few sentences telling about their person.
