La Comunitat 4 aquest any hem iniciat un bloc de ci\u00e8ncies. Cada dilluns, l’Ariadna ve a l’escola i ens proposa experiments per descobrir coses sobre la mat\u00e8ria.<\/p>\n

Vam comen\u00e7ar experimentant amb llavors.<\/h4>\n

Si posem una llavor en un pot amb una mica de cot\u00f3 o paper humit, al cap d’una setmana la llavor ha comen\u00e7at a germinar. De la llavor surten dos “fils” que no s\u00f3n el mateix: un \u00e9s l’ARREL i l’altre \u00e9s la TIJA.<\/p>\n

Alguns vam voler veure qu\u00e8 passava en diferents situacions. Per exemple, si les pos\u00e0vem en un lloc fosc.<\/p>\n

A falta de llum, les llavors creixen m\u00e9s r\u00e0pid. La tija i les arrels de la llavor que estava a la foscor eren m\u00e9s llargues, per\u00f2 no tenien color verd. Les que havien estat a la llum eren m\u00e9s curtes per\u00f2 tenien m\u00e9s color verd i tenien m\u00e9s fulles.<\/p>\n

CONCLUSI\u00d3: Les plantes per cr\u00e9ixer necessiten llum i aigua.<\/p>\n

<\/h4>\n

Experiment 2: C\u00f3m afecta l’evaporitzaci\u00f3 de l’aigua a la planta?<\/h4>\n

<\/h4>\n
\"\"<\/a>
Experiment, evaporitzaci\u00f3<\/figcaption><\/figure>\n

\u00a0Vam tancar una branca de la planta a dins d’una bossa de congelar. Vam esperar un cap de setmana.<\/h4>\n

Quan la vam mirar a una de les plantes li havia sortit una arrel!<\/p>\n

En una altra planta la bossa est\u00e0 plena d’aigua.<\/p>\n

<\/h4>\n

 <\/p>\n

CONCLUSI\u00d3: l’aigua que est\u00e0 dins la planta tamb\u00e9 s’evapora.<\/p>\n

<\/h4>\n

Experiment 3: C\u00f3m agafa l’aigua la tija?<\/h4>\n

\"\"<\/a><\/p>\n

Per fer aquest experiment, vam posar unes branques d’api dins de pots d’aigua amb colorant.<\/p>\n

 <\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

A la foto surt l’aram mirant un tall molt petit de la branca d’api. Com que l’aigua era blava, la tija s’havia tornat una mica blava i tenia petits forats plens d’aigua blava.<\/p>\n

Altres vam mirar el tall pel microscopi: vam veure petits ex\u00e0gons.<\/p>\n

CONCLUSI\u00d3: l’aigua puja per la tija, va cap a les fulles i s’evapora. Aix\u00f2 \u00e9s una part de la fotos\u00edntesi. \u00c9s com si la planta tingu\u00e9s venes.<\/p>\n","protected":false},"excerpt":{"rendered":"
