The SproutLab cast

Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.

  1. Hatch Guess-then-find-out — a curious just-hatched chick who predicts what will happen, then checks.
  2. Blink Light — a firefly whose glow shows how we can only see things when there's light.
  3. Rattle Sound — a woodpecker whose drumming shows that sound comes from things that shake.
  4. Frost Changing matter — an ice friend who melts and freezes again, showing what can and can't go back.
