Jeudi dernier, le 16 novembre, nous avons d\u00e9but\u00e9 notre travail sur les \u00e9tats de l’eau et les changements d’\u00e9tat. Philippe, des Amis de la main \u00e0 la p\u00e2te<\/em>, nous accompagnera durant tout notre projet.<\/p>\n

Pour cette premi\u00e8re s\u00e9ance, nous souhaitions r\u00e9pondre \u00e0 la question suivante : pourquoi met-on du sel sur les routes lorsque le sol est gel\u00e9 ?<\/p>\n

Mais avant d’y r\u00e9pondre, les \u00e9l\u00e8ves ont pu exp\u00e9rimenter la fonte d’un gla\u00e7on sur trois mat\u00e9riaux diff\u00e9rents : le bois, le plastique et le m\u00e9tal. Lors de cette exp\u00e9rience, les \u00e9l\u00e8ves ont suivi les \u00e9tapes de la d\u00e9marche d’investigation et cette mise en oeuvre a \u00e9t\u00e9 tr\u00e8s concluante. Les \u00e9l\u00e8ves ont observ\u00e9 que c’est sur le m\u00e9tal que le gla\u00e7on fond plus vite. Cette premi\u00e8re exp\u00e9rience a permis aux \u00e9l\u00e8ves de d\u00e9couvrir la fusion : passage de l’\u00e9tat solide \u00e0 l’\u00e9tat liquide.<\/p>\n

Pour r\u00e9pondre \u00e0 la question initiale, Philippe a utilis\u00e9 deux r\u00e9cipients : l’un contenant de la glace pil\u00e9e et l’autre de la glace pil\u00e9e et du gros sel. A l’aide de thermom\u00e8tres, les \u00e9l\u00e8ves ont pu constater que la temp\u00e9rature de la glace seule est de 0\u00b0C et est de -10\u00b0C pour celle avec le gros sel. Ils observent donc que la glace avec le sel est liquide plus rapidement, ce qui est souhait\u00e9 lors du salage des routes.<\/p>\n

D\u00e9but d\u00e9cembre, les \u00e9l\u00e8ves vont pouvoir poursuivre ce travail et exp\u00e9rimenter un nouveau changement d’\u00e9tat.<\/p>\n
