Hi- i'm Carlos - one of the kids in Ms Frizzle's class. When I brought my mystery rock to school- I was hoping Ms Frizzle could tell me what kind of rock it was. But the Friz doesn't like to tell when she can show. That's how we ended up on a wild rock hunt in the wild west- trying to solve my mineral mystery! We took an awesome stagecoach ride- panned for precious gems and even explored an old mine. Sure the going got a little rough at times - but in the end- this road trip rocked!
