It's a spring morning, and Miss Mingo and her class are ready to hike up High Hill to visit the weather station. Groundhog predicts the weather will be perfect. But as the animals climb, the temperature does, too, and Panda seeks shade while Hippo starts sweating red (it's normal!). From hail and winds to rain and a sudden chill, everyone from Ant to Alligator is learning about crazy atmospheric changes. Sprinkled with facts about weather and animal habits, this charming class trip will bring sunny smiles.
