Abraham's pumice rock that he brought to class today


Pumice is a light rock. It comes shooting out of a volcano as lava.

It is boiling hot when it shoots out a volcano.

Some people use pumice to clean their feet.

Pumice is like scoria because it has holes in it.

  1. Thanks for bringing your pumice to school today, Abraham. It is amazing how light pumice is to hold, although it looks very heavy!
