El passat trimestre els nens i nenes de 3r B vam voler fer un experiment:
\nTen\u00edem les instruccions per muntar uns avions de paper i uns fulls de colors molt xulos. Per equips vam construir els diferents avions que es deien \u201cFletxa\u201d, \u201cTorpedo\u201d, \u201cCl\u00e0ssic\u201d i \u201cPlanejador\u201d i vam voler investigar quin d\u2019aquests avions volaria m\u00e9s r\u00e0pid. Pensant entre tots vam adonar-nos que hav\u00edem de tenir en compte dues coses: la dist\u00e0ncia que volarien els avions i el temps que estarien volant. I que aquestes dades ens dirien la velocitat a la que volava cada avi\u00f3.
\nVam dissenyar el nostre experiment i vam anar apuntant a les nostres llibretes qu\u00e8 necessit\u00e0vem per fer aquest experiment: quin material far\u00edem anar, quins passos hav\u00edem de seguir i quines hip\u00f2tesis f\u00e8iem. Per suposat ens vam repartir la feina; un membre del grup seria el secretari\/a i anotaria les dades, un altre\/a s\u2019encarregaria de llen\u00e7ar l\u2019avi\u00f3, un altre\/a de cronometrar els segons que est\u00e0 volant i un altre\/a mesuraria amb la roda m\u00e8trica la dist\u00e0ncia recorreguda per l\u2019avi\u00f3. Durant el proc\u00e9s vam tenir algun contratemps perqu\u00e8 un dels avions no volar. El vam haver de canviar per un altre.
\nQuan ja vam tenir totes les dades recollides vam comparar els resultats i vam veure que l\u2019avi\u00f3 m\u00e9s r\u00e0pid havia estat el \u201cCl\u00e0ssic\u201d.
\nEn el proc\u00e9s de raonar i pensar el nostre experiment tamb\u00e9 va sorgir un dubte: a quina velocitat som capa\u00e7os de c\u00f3rrer nosaltres? I un cotxe o un avi\u00f3, a quina velocitat van? Vam comen\u00e7ar a fer hip\u00f2tesis per\u00f2 per saber-ho del cert el millor era mesurar-ho i sortir de dubtes. I aix\u00ed ho vam fer. Vam mesurar el camp de futbol gran amb la roda m\u00e8trica per saber quants metres recorrer\u00edem (que eren 27) i la Irene va mesurar amb un cron\u00f2metre els segons que tard\u00e0vem a fer aquests metres. Un cop a la classe, vam con\u00e8ixer que per calcular la velocitat hav\u00edem de fer una divisi\u00f3; dividir els metres recorreguts entre els segons que est\u00e0vem corrent. Vam ser conscients que la dist\u00e0ncia seria la mateixa per tots per\u00f2 el temps canviaria per cadasc\u00fa de nosaltres i que si est\u00e0vem m\u00e9s segons corrent la nostra velocitat seria m\u00e9s baixa i si est\u00e0vem menys segons corrent la nostra velocitat seria m\u00e9s alta.
\nFinalment, per acabar la nostra experi\u00e8ncia vam treballar unes fitxes t\u00e8cniques d\u2019uns avions i vam poder veure a quina velocitat volen. La nostra velocitat la vam mesurar en metres per segon per\u00f2 la velocitat dels cotxes i els avions es mesura en quil\u00f2metres per hora!!<\/p>\n","protected":false},"excerpt":{"rendered":"
