Are there rocks in outer space?
If continents didn't move, would we have volcanoes?
How are rocks formed?
—Fourth grade students of teacher Ann White at the Jackson Academy, East Orange, New Jersey
As Ann White's students studied the nature of rocks, the questions poured forth from them so much that the 4th grade teacher called them “Rock Hounds.” Their questions provided a guide for a unit focused on the mysteries and wonderment of nature's building blocks. Ann structured their inquiries as a problem-based learning unit that used a wide variety of resources, including the Internet and a local geologist.
