The Hippo Campus — Theodore Allen Lightfoot

In Book 1 of The Hippo Campus series, your child learns about the properties of buoyancy by traveling to a university campus populated entirely by hippopotamuses!
This rhyming, interactive book keeps children engaged in learning and provides an opportunity to experiment with buoyancy at home.
The Hippo Campus series is based on solid research of the brain, child development, and the topic studied â€" in this case, buoyancy. Sit back and enjoy this book with your child!
