Starting with buds and seeds, Uncle George inspires Tom, Frank, and Dolly to observe changes in plant growth over days and even weeks. By setting up an aquarium for their finds from the pond, Uncle George faciliates their observation of the life cycle of frogs, toad, and newts. And building a larva cage with multiple compartments provides housing for caterpillars and caddis worms so his youthful companions can watch their transformation into butterflies and caddis flies.Throughout Uncle George asks questions to prompt their discoveries and guide their comparisons.
