Float or sink?

Predict floating, sort by material, order the water-ice transformation.

Put each object where you think it will go: float or sink?

Objects to sort

Learning objectives

Kindergarten
Matter and objects: explore matter, observe simple transformations, handle (French curriculum, age 5+). The app carries the **prediction** and **trace** ; physical handling stays in class. Epistemic stance: no 'wrong', prediction errors are valuable.

About this activity

A scientific anticipation workshop for kindergarten. The child predicts whether each object will float or sink: V1 does not auto-validate (real experiment happens in class, *La main à la pâte* approach). V2 sorts by material. V3 orders water → ice → water. No score, infinite restarts.

Using this activity in class

Kindergarten: used before or after a real float/sink experiment with a tub of water and real objects. The app supports anticipation and trace-keeping.
