Float or sink?
Object 1 of 8
Steel spoon
Will it float or sink? Guess first!
Floated 0
Sank 0
A tick means you guessed right. A circle means a surprise.
For grown-ups: every result here is what happens in plain tap water. The steel katori floats when it is set down gently, right way up. Try it in a bucket and see.
Well played! Now try the real one.
Real water and real things from your kitchen beat any screen. Fill a bucket, make the FLOAT and SINK chart, and talk about why the katori floats and the coin does not.
Float or Sink: The Kitchen Lab →Play it together
Before each tap, ask your child why they think it will float or sink. Any reason is fine. When the water gives a surprise, ask how that is possible, and let them think before you say anything.
What it practises
Guessing first, then checking. That is all we claim for it. The real version,Float or Sink: The Kitchen Lab, does the same job with things from your kitchen, and does it better.
Five minutes on the screen is plenty. No sign-up, no sound, no ad networks, and nothing your child types leaves this page. More games in the Play corner.
Questions parents ask
Why does the game make my child guess before the object drops?
Because the guess is what turns splashing into an experiment. The real activity starts with a FLOAT and SINK chart filled in before anything touches the water. A wrong guess is not a failure here. It is a surprise, and surprises are the good ones.
Does a steel katori really float?
Yes, if you set it down gently, right way up, in a bucket of water. A small coin sinks, but a big steel katori floats, and that goes against the idea that heavy things sink. Ask your child how that is possible and give them a minute to think before you explain anything.
