Com cada any, aquest mes de maig els alumnes de TA, TB i TC han sortit a la pla\u00e7a d\u2019Angeleta Ferrer per fer una activitat a l’aire lliure: mesurar l\u2019al\u00e7ada de l\u2019institut i d\u2019altres elements del paisatge urb\u00e0, com fanals o arbres. Per\u00f2 no ho hem fet amb escales ni instruments complicats, sin\u00f3 amb les ombres! A partir de la relaci\u00f3 entre la nostra altura i la longitud de la nostra ombra, hem aplicat els principis de semblan\u00e7a per calcular al\u00e7ades que, a simple vista, s\u00f3n inaccessibles.<\/p>\n

Ha estat una manera pr\u00e0ctica de veure com les matem\u00e0tiques funcionen en la vida real. De fet, hem utilitzat el mateix m\u00e8tode que ja feia servir Tales de Milet<\/span><\/span> fa m\u00e9s de dos mil anys per mesurar l\u2019al\u00e7ada de les pir\u00e0mides. Una experi\u00e8ncia diferent que ens ajuda a entendre millor la geometria.<\/p>\n
