The Magic School Bus Gets Swamped
Field Trip Notes
The debate is intense: Should Walkerville get rid of the swamp by the river and replace it with a fantastic new shopping mall, or build the mall somewhere else? Carlos, representing his class, is given the thankless task of persuading the town council to keep the smelly old swamp. And if he loses the debate, he loses to...Janet! The kids discover that the swamp is an important habitat and a natural water filter. But the council is not convinced to keep it until...FLOOD!
