Math & Science

biOrb Aquarium Kit with Light FixtureObserve real sealife in your very own aquarium. A small aquarium (or just a fishbowl) can be cheap and easy, and preschoolers love being responsible for feeding their fish.
Demonstrate how long a blue whale can be with a long piece of rope, about 100 feet. Then cut a rope as big as your child and see how many it takes to make a whale.

Learn about sea life along with your child by looking at the beautiful photos in the book Ocean, published by The American Museum of Natural History.

Visit an aquarium near you to see the creatures up close. To find an accredited aquarium near you, search for your city at the Association of Zoos and Aquariums website.
