Rock Types 2

All rocks include two or more minerals but greatly vary in appearance. The online interactive encourages scholars to match the rock types to the facts they know about each. They then complete three grid puzzles reviewing the same information. For those without Internet access, the resource offers a worksheet with the same content.
