How a lesson works
Watch or play
Short animated films with captions, and games with Little levels for ages 4 to 6 and Big levels for 7 to 9. Read-aloud uses your device's voice and can be switched off.
Explore
Films end with a hands-on lab, like the Color Lab where you mix light and paint. Games let kids guess, test and try again as often as they like.
Try it
Each lesson comes with notes for grown-ups: the big ideas, quick experiments and questions to ask.
