El nostre grup hem triat\u00a0 l’ experiment del foc de colors, hem pensat que era bona idea i a sobre \u00e9s bonic. Els materials necessaris s\u00f3n:<\/span>
\n– \u00c0cid b\u00f2ric.<\/span>
\n-Alcohol 96\u00ba<\/span>
\n-Uns guants de l\u00e0tex<\/span>
\n-Paper d’ alumini<\/span>
\n-Platets per les espelmes<\/span>
\n-Un encenedor<\/span>
\n
\n<\/span>
\nPassos a seguir:<\/span>
\n
\n<\/span>
\n1r.\u00a0 Abocar una mica d’\u00e0cid b\u00f2ric a un d’els platets junt amb una mica d’alcohol i a l’altre nom\u00e9s alcohol.<\/span>
\n2n.
\nAmb l’encenedor, cremem l’alcohol que hi ha als dos platets, veur\u00e0s que
\nen un platet la flama surt verda i en l’ altre blava.<\/span>
\nAix\u00f2, passa perqu\u00e8 el foc emet radiaci\u00f3 electromagn\u00e8tica que segons la longitud d’ona canvia de color.<\/span>
\nCada material t\u00e9 un patr\u00f3 i una longitud d’ona per aix\u00f2 el foc canvia de color <\/span><\/p>\n

El nostre grup hem triat l’experiment del globus i el got perqu\u00e8 ens va semblar molt divertit. El material necessari \u00e9s:<\/span><\/div>\n
-un globus<\/span><\/div>\n
-un got petit<\/span><\/div>\n
-un recipient amb aigua<\/span><\/div>\n
-una espelma i un encenedor<\/span><\/div>\n
\u00a0<\/span><\/div>\n
Passos a seguir:<\/span><\/div>\n
1r.\u00a0 Encenem l’espelma amb l’encenedor i bolquem el got a sobre.<\/span><\/div>\n
2n.\u00a0 Quan el got est\u00e0 calent agafem el globus i l’ajuntem. <\/span><\/div>\n
3r. \u00a0 Amb molt de compte posem el globus i el got al recipient d’aigua.<\/span><\/div>\n
