Cracking the Egg: Egg-Laying Animals

What can an egg tell us about the animal growing inside? In this hands-on science box for kids, young explorers take a closer look at eggs, reproduction, and animal life cycles through the lenses of three very different creatures. Discover the incredibly tiny eggs of a Hummingbird, meet the Ostrich, which lays the largest eggs of any living bird, and uncover one of the animal kingdom’s biggest surprises—the Platypus, a mammal that actually lays eggs!

Kids investigate the different parts of an egg through a hands-on egg dissection, then turn an everyday plastic bottle into a recycled hummingbird feeder to observe birds right outside their own home.

From tiny eggs to giant ones—and from birds to an egg-laying mammal—Cracking the Egg combines biology, observation, and creative activities to show kids that there is much more inside an egg than meets the eye.
