Metallic Review
The following suggestions are to be
used with the nine metallic minerals we have previously discussed.
- Discuss which metals were or are used in pipes, why some are
still used and why others aren’t.
- Try to get a sample of each metal and do several experiments
with them as a group. For example, which ones rust, bend easily, scratch hard and soft
surfaces, and so on.
- Estimate how much of a specific metal it would take to make a
pound. Where samples are available, demonstrate the actual amount with a scale.
- Divide class into small groups. Have each group pick the name of
a metal from a hat. Each group should give clues to the class, who try to guess which
metal the group represents. Some metals may be repeated or left out to avoid answers by
elimination.
- Make
a bar graph depicting each metal and its weight relative to water. May be done on a master
form by each student or as a bulletin board or wall mural.
