KindergartenScience Labs

Real science for 5-year-olds, one tap at a time

Eight hands-on virtual labs where children wonder, guess, test and explain. Every word is spoken aloud with captions, so children who can't read yet can explore on their own.

Wonder and guessA short, real scene to notice something, then a guess before testing.
Test and thinkPush, build, water, watch the weather: the child does it and sees what happens, then explains why.
