Lecture/Discussion: Using the book, observe and discuss the
differences between rocks and minerals, and then rock types (igneous,
sedimentary, and metamorphic).
Activity: Bring out rock samples from each type (for example:
igneous—granite, diorite, basalt; sedimentary—sandstone, shale,
limestone, conglomerate; metamorphic—gneiss, marble, or slate).
Have students describe the rocks. Color, texture, size, mass (heft),
roundness, angularity, etc may be important contributors to their
instruments.
Have the students describe which work better at being shaken, struck,
or scraped.
Create instruments from the rocks. Use other materials (toilet paper
rolls, rubber mallets, paper, tape, etc.) to enhance sounds or to strike
the rocks. For example, sandstone pieces can be scraped together,
marble can be hit with rubber mallet, small pieces can be made into
shakers with toilet paper rolls and tape.
Have a rock concert
Observe reasons for the different sounds.
Make suggestions about the composition and nature of each specimen.
