Points importants du cours :
L’\u00e9lectricit\u00e9 est une \u00e9nergie g\u00e9n\u00e9ralement obtenue par le mouvement de charges \u00e9lectriques, en particulier les \u00e9lectrons. Elle se caract\u00e9rise par plusieurs \u00e9l\u00e9ments : la tension (V), l’intensit\u00e9 (I) et la r\u00e9sistance (R).<\/p>\n

En \u00e9lectricit\u00e9, nous utilisons la loi d’Ohm qui stipule que l’intensit\u00e9 du courant dans un circuit est directement proportionnelle \u00e0 la tension appliqu\u00e9e et inversement proportionnelle \u00e0 la r\u00e9sistance du circuit : I = V \/ R.<\/p>\n

Un autre aspect important concerne les conducteurs et isolants. Les mat\u00e9riaux conducteurs permettent aux charges de se d\u00e9placer facilement tandis que les isolants bloquent leur passage.<\/p>\n

Consignes pour l’exercice :
Pour ce travail, chaque \u00e9l\u00e8ve recevra une s\u00e9rie de phrases avec des mots manquants relatifs au cours sur l’\u00e9lectricit\u00e9. Le but est de compl\u00e9ter ces phrases correctement selon les connaissances acquises en classe. Apr\u00e8s avoir termin\u00e9, vous \u00e9changerez vos travaux avec le pair \u00e0 votre droite pour une correction commune.<\/p>\n

Exercice \u00e0 trous :<\/p>\n

1 – L’\u00e9nergie \u00e9lectrique est g\u00e9n\u00e9ralement obtenue gr\u00e2ce au mouvement des _______.
2 – La loi d’_______ stipule que I = _______\/_______.
3 – Un mat\u00e9riau _____ laisse passer facilement le courant alors qu’un mat\u00e9riau ______ l’emp\u00eache.<\/p>\n

R\u00e9ponses :<\/p>\n

1 – \u00c9lectrons
2 – Ohm ; V ; R
3 – Conducteur ; Isolant<\/p>\n

Adaptation aux \u00e9l\u00e8ves dyscalculiques :
Cet exercice a \u00e9t\u00e9 con\u00e7u pour \u00eatre accessible aux \u00e9l\u00e8ves dyscalculiques car il n’inclut aucune op\u00e9ration math\u00e9matique complexe ni aucune demande de calcul pr\u00e9cis. De plus, tous les termes utilis\u00e9s ont \u00e9t\u00e9 largement expliqu\u00e9s en classe auparavant \"\"\"!<\/p>\n","protected":false},"excerpt":{"rendered":"
