Before you start
Pick a lab
Light Lab Guess what the light does with Blink — then shine it and see! 
Sound Lab Guess where the sound comes from with Rattle — it is all about the shake! 
Matter Lab Guess if it can change back with Frost — melt, freeze, and find out! Sink or Float? Guess if each thing will sink or float — then drop it in and see! Make It a Fair Test Set up a test that changes only ONE thing — the fair-test rule! My Wonder Project Wonder about something — then look, try, and show what you find! Meet the cast — the characters who teach this
-
Hatch Guess-then-find-out (hero) — a curious just-hatched chick who predicts what will happen, then checks. -
Blink Light — a firefly whose glow shows how we can only see things when there's light. -
Rattle Sound — a woodpecker whose drumming shows that sound comes from things that shake. -
Frost Changing matter — an ice friend who melts and freezes again, showing what can and can't go back.
