Darrerament, els xiquets i xiquetes de tercer hem finalitzat el projecte de les m\u00e0quines. Durant la realitzaci\u00f3 d\u2019aquest projecte hem apr\u00e8s molt\u00edssimes coses: qu\u00e8 \u00e9s una m\u00e0quina, la difer\u00e8ncia entre una m\u00e0quina simple i composta, l\u2019evoluci\u00f3 de les m\u00e0quines durant el transcurs de la hist\u00f2ria, el funcionament de les m\u00e0quines simples (la politja, la palanca, el pla inclinat\u2026) i els components que integren les m\u00e0quines compostes. A m\u00e9s, hem vist c<\/span>om les m\u00e0quines es mouen gr\u00e0cies a les forces i hem realitzat experiments per comprovar com funcionen les diferents forces: <\/span>for\u00e7a de la gravetat, electromagn\u00e8tica i est\u00e0tica.<\/span><\/p>\n

Finalment, hem investigat sobre la roda que va ser un dels grans descobriments de l\u2019\u00e9sser hum\u00e0 i la pascalina, la primera calculadora que funcionava a base de rodes i engranatges inventada per Blaise Pascal.<\/span><\/p>\n
