Comment jouer ?
Découvre la masse de la boite surprise
Clique et déplace des masses sur le plateau droit de la balance.
Lorsque les deux plateaux sont à la même hauteur, ils sont à l'équilibre : les deux plateaux portent la même masse.
Lorsque tu as équilibré les 2 plateaux, clique sur le garçon. Si les 2 plateaux sont à l'équilibre, tu peux alors écrire la masse de la boite dans le cadre rose.
Compte la masse totale que tu as placée sur le plateau. Ecris ce nombre dans le cadre rose puis clique sur le garçon pour vérifier ta réponse.
Pédagogie
