The Magic School Bus Revving Up
Field Trip Notes
When The Magic School Bus's engine stops running, Mr. Junkett, a vehicle maintenance inspector, decides the bus should be junked. The class shrinks, dons fireproof suits and masks, and heads for the engine -- from the inside! There, they discover that the peanut-butter that Junkett accidentally dropped into the engine is blocking the fuel line, stopping air from mixing with gas, and keeping the spark plugs from sparking. While cleaning up the mess, the kids learn how an engine works. Can they get the Bus working again before Junkett has it pounded into a pancake?

Time: 40 minutes
Group size: Four
Since your students can't travel through The Magic School Bus's engine, to see what gets the wheels turning, they can explore another way to turn wheels: propulsion. Here, they'll see how the push from air-filled balloons turns the wheels of milk-carton 'buses.'
