Sky Island

science · weather · the water cycle · evaporation and condensation · rain, snow and rainbows

A floating island high in the sky has lost its weather, and Nimbus the cloud sprite needs a new Weather Keeper. Children warm the lake, grow clouds, blow rain over thirsty fields, freeze snow onto a mountain, hunt for a rainbow and ride out a cozy thunderstorm, and every idea they discover brings more of the island back to life.
