The Magic School Bus Rocks and Rolls
Field Trip Notes
To celebrate the founding of Walkerville, Mrs. Frizzle's class sculpts a stone likeness of Walkerville's founding father, Captain Walker - but the statue tumbles down the mountain. Ms. Frizzle turns the bus into a giant boulder, the kids into rock-kids, and they give chase. By the time they reach the celebration at the base of the mountain, they've been pushed, tossed, sanded, polished, and eroded by water - as has the statue, now the size of the soccer ball. The kids are sure they've let everyone down - until they look back at the mountain for the surprise of their lives!
Time: 30 minutes
Group Size: 4
Arnold and the other kids enlist the power of water erosion to sculpt stone! Your kids explore how running water moves earth and creates new landforms.
What You Need
Ahead of time: Find books about local geology. Fill a bucket with local soil. Ask kids to bring in a water-eroded rock. Ask: What will you look for? (smooth, sculpted shape; ice cleavages)
Talk About It
Ask: How might water have changed your rock? What evidence do you see? How might water move rocks to faraway places?
What To Do
Draw timelines of the kids’ rocks. Decide on a time scale, and let kids give their ideas for: where their rock was a very long time ago and what it looked like; where it was found; where it will be and how it will look a long time in the future.
