Grow A Frog for $15.20

Teacher Review Watching a creature grow from birth to maturity is a special science lesson that most urban children seldom experience. The process of metamorphosis is especially fascinating. The Grow A Frog kit comes with a see-through 3.5-by-4.5-inch plastic aquarium, a small bag of tadpole food and another of nutri-rocks, a piece of fake seaweed, and a detailed handbook with directions.
