What you’ll learn

  1. Starting Small: The Egg and CaterpillarLearn that a butterfly's life begins as an egg that hatches into a hungry caterpillar.A butterfly's life begins as a tiny egg laid on a leaf. Out of the egg wriggles a caterpillar, which is always hungry and munches on leaves all day. As it eats, the caterpillar grows bigger and stronger.
  2. A Big Change: ChrysalisUnderstand that a big caterpillar makes a chrysalis and changes inside it.When the caterpillar grows too big for its skin, it wriggles out of it a few times. When it is big enough, it makes a hard case called a chrysalis and hangs very still. Inside the chrysalis, the caterpillar slowly changes. The whole journey is a circle: egg, caterpillar, chrysalis, butterfly.
  3. A Beautiful ButterflyLearn that a butterfly comes out of the chrysalis and can lay eggs to start the cycle again.When the chrysalis opens, a beautiful butterfly climbs out with soft, crumpled wings that soon dry and spread wide. Then it flutters into the sky. The butterfly can lay eggs of its own, so the amazing story starts all over again.
