The Magic School Bus Plays Ball
Field Trip Notes
Ralphie's delighted! Ms. Frizzle's class is going to a baseball game. Of course, it's a very special baseball game. The Magic School Bus shrinks and takes Ms. Frizzle and the kids inside a book to a frictionless baseball field. Ralphie hits a homer he'd never have imagined in the world of friction, and all the kids find out about friction and other pushes and pulls. But when they get on the Bus to head back to school, the book closes with them inside it. How can they get out of the book? Can what they've learned about forces and friction help them make it home?
What a difference friction makes! When Ms. Frizzle's kids get off the Bus into the world of nonfriction, they can't even walk. Your kids can work in small groups to find how movement chanes when there is more - and less - friction.
What You Need
Talk About It
Help children think about friction by asking: Where would be a good place to slide? Why?
What To Do
Discuss other ways besides rollers to make less friction between the box and the table. Try putting marbles, sugar, or ice under the box.
