Join Peep, Chirp and Quack on six exciting, new adventures. Find out what a "whatchamacallit" is. Discover where the sun goes at night. Figure out how to un-flip a turtle. And learn why a step, a squirm, and a hop are very different measurements. There's a big wide world out there and it's waiting for YOU! Then join real kids as they experiment and play in their OWN "big wide worlds." Build bridges. Make shadow puppets. Track shadows. Find funny ways to measure yourself. It's all part of your scientific research!
