La sessi\u00f3 d’experimentaci\u00f3 d’avui ens ha servit per descobrir la for\u00e7a de l’electricitat est\u00e0tica. A trav\u00e9s de petites activitats hem observat els intercanvis d’energies que succeeixen entre diferents materials.<\/p>\n

Per iniciar la sessi\u00f3, hem hagut d’obtenir una acumulaci\u00f3 d’electrons de c\u00e0rrega negativa. Aix\u00ed que hem fregat de valent un globus en el cap. En aquest procediment hem aconseguit que el globus obtingui una alt nivell d’electrons. Tot seguit hem apropat el globus a diferents materials conductors, primer a una llauna, despr\u00e9s a petits trossets de paper i finalment a bombolles de sab\u00f3.<\/p>\n

Hem quedat\u00a0parats al veure com cada material es movia amb l’electricitat que duia el globus. L’explicaci\u00f3 \u00e9s molt senzilla, els electrons del globus atrauen als protons de c\u00e0rrega positiva i per aix\u00f2 un objecte despla\u00e7a a l’altre.<\/p>\n
