Wonder, guess, test, think.
Every lab walks through a real investigation, sized for 5- and 6-year-olds. Here is Push the Ball!, step by step.
Wonder
A short, real scene to notice something. Tap the hand, and a push makes the ball roll.
Guess
Before testing, children make a prediction by tapping a picture: will a soft or a hard push go farther?
Test
They run the experiment themselves. Flags mark where each push stopped and a picture chart fills in.
Think
The narrator asks what happened and why, and checks the guess. Scientists test their ideas.
Challenge
A small problem to solve with the new idea: which push knocks the tower down?
Badge
The big ideas in one sentence, a badge, and a lab record to print or save.
Made for little scientists
Built for five-year-olds, not squeezed down from grade 5.
Every word read aloud
A friendly narrator says every line, and a caption shows it. No reading needed, ever.
Tap, don't type
Big pictures to tap, nothing to spell, no timers, no scores to lose.
Real investigations
A guess first, then a fair test, then an explanation. The steps scientists use, one tap at a time.
Badges and lab records
A badge at the end of each lab, a printable lab record, and a certificate when all 8 are done.
A grown-ups corner
Buying and settings sit behind a grown-ups question. Each lab has talk-about-it questions for you.
Private by design
No accounts, no ads, no tracking. Your child's badges stay on your device.

Try it for real Roll a ball down a hallway with a soft, a medium and a hard push, and mark each stop with a piece of tape. Then tie a string to a toy car and compare a gentle pull with a strong one.

Questions
Grown-ups usually ask…
My child can't read yet. Can they really use the labs on their own?
Yes - that's what they're built for. Every line is spoken aloud and shown as a caption, and children tap big pictures instead of typing. Sit with them for the first lab; after that most 5- and 6-year-olds explore happily with a grown-up nearby.
What devices does it work on?
Any modern web browser: iPad and iPhone (Safari), Android tablets, Chromebooks, Windows and Mac. Open k5stem.com/play/kindergarten - there's nothing to install and no account to make. Turn the sound on: the labs are narrated.
Are the labs aligned to the standards?
Each lab targets one of the 8 NGSS* Kindergarten performance expectations - together they cover the whole Kindergarten year. Every lab page names its standard, the science practice it uses, and links to the official text.
What does it cost?
Push the Ball! is free - no sign-up. The other 7 labs unlock with one payment: Family $19 (one household, up to 5 devices) or Classroom & Co-op $49 (one class or group, up to 30 devices). No subscription, and updates to the labs are included.
What if it isn't right for us?
Ask within 30 days of buying for a full refund - just reply to your Gumroad receipt email.
