Objective:
Students will be able to match cards that tell talc properties
and uses with corresponding talc products to demonstrate their
awareness of the uses of talc.
Preparation
of Materials:
1.
Print the accompanying pages on a printer (in color, if possible).
2.
Cut out the card fronts and backs from the printed pages. Use
a paper cutter if possible so that the edges are straight.
3.
Cut 12 squares of mat board measuring 3 1/2 x 3 1/2 inches. Glue
the card fronts that list talc properties to the fronts and the
corresponding product pictures to the backs.
4.
Obtain a plastic shoebox. Use wide clear package tape to affix
the label "Uses of the Clay Mineral Talc" to the outside
of each end of the box.
5.
Cut out the "Directions" card and glue to a mat board
rectangle measuring about 4 1/2 by 6 inches.
6.
Find an example of each of the products that will fit into the
shoebox.
Lesson
Instructions:
Pass
around a hand specimen of talc. Ask students to brainstorm its
properties (white, slippery, powdery, soft, etc.) Then ask students
to suggest any uses they can for this mineral (often students
are aware that talc is used in body powder.) Finally, allow students
to work in small groups to match cards that list properties of
talc with corresponding products. They will probably be surprised
at the many uses of talc.
