As part of a project related to “Exploring the world” in Kindergarten called “Float or sink?”, the children of Moyenne Section class, in teams of 2, with their two teachers in co-intervention, made an object whose challenge was to float. After making them and describing the materials used (the floating ability of 6 materials had previously been observed), the children were able to experiment and observe the result of their object on the water.  All were floating!  Well done kids!
