2nd and 3rd grade Navigators collaborate to identify rocks. Are these sedimentary, igneous or metamorphic rocks? Which ones are volcanic rocks again? What kind of experiments can we perform with rocks?
Why would the same kind of fossils be in North America and South America? How would they get there? Do you think the continents fit together like a puzzle? What kind of proof is there that Pangaea really existed?
I've seen these rocks near Mount Rainier! These rocks look like the Grand Canyon! How was the Grand Canyon formed again?
Are these gems valuable? What is the difference between rocks and minerals? Where do you find diamonds? How are they formed?
