Introduction transcript

Welcome to Sink or Float! Make a prediction and test what floats. Join Bobi and Mim, take your time, and try one little challenge at a time. A grown-up can help, and you can pause whenever you like.

Notes for a grown-up

Predetermined object models must be specified; heaviness alone does not determine floating; no unsupervised water play.

Completion shows participation, not proven mastery. Encourage discovery, provide help and take a break when needed.
