Field Trip Notes Wanda brings Bella, her pet bullfrog, to school and starts to set up a habitat for her in the classroom. Bella has other ideas, however. She hops out the window and heads for parts unknown. The class hops after her - in the Magic School Bus turned bullfrog. After searching in a few habitats, the kids find Bella in a lovely pond that’s just right for a frog to live in. But how will Bella escape the predator heron? And if Bella lives there, won’t Wanda be lonely without her?         What does an animal need in its habitat? Wanda learns that her pet bullfrog needs food, water, shelter, and a place to raise its young. Your kids can work in groups to set up temporary indoor homes for earthworms. They can observe the earthworms in an environment similar to the natural one.
