Les docents havien constru\u00eft un prototip senzill, d\u2019una sola ampolla, i el van fer volar (UAU!). La segona vegada, per\u00f2, no es va enlairar. Aix\u00f2 ens va generar moltes preguntes: Per qu\u00e8 vola, el coet? Qu\u00e8 ha passat la segona vegada per a qu\u00e8 no s\u2019enlair\u00e9s? Com d\u2019amunt pot arribar? Aquestes preguntes i d\u2019altres ens han acompanyat durant el trimestre.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">L\u2019alumnat, per\u00f2, no s\u2019ha conformat amb el prototip senzill, sin\u00f3 que han constru\u00eft un coet de dues ampolles, havent de parar molta atenci\u00f3 a com s&#8217;enllacen per no perdre pressi\u00f3 d\u2019aire a la junta. Alguns alumnes han pogut aprendre com manipular el metall per a fer la junta, mentre d\u2019altres averiguaven com es pot descriure el moviment amb gr\u00e0fics. Com que han esdevingut experts en enginyeria i f\u00edsica, han pogut transmetre aquest coneixement a la resta per a treballar de forma cooperativa.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Durant el projecte hem fet molts llan\u00e7aments per poder descriure el moviment del coet, i fer-ne millores. Els coets han pogut resistir els llan\u00e7aments gr\u00e0cies al paracaigudes, que ha perm\u00e8s frenar la caiguda lliure i poder observar un tram nou en el moviment del nostre coet: la caiguda a velocitat constant.<\/span><\/p>\n<p><a href=\"https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1963\" src=\"https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/1.jpg\" alt=\"\" width=\"269\" height=\"151\" srcset=\"https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/1.jpg 512w, https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/1-300x169.jpg 300w\" sizes=\"auto, (max-width: 269px) 100vw, 269px\" \/><\/a> <a href=\"https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1964\" src=\"https:\/\/agora.xtec.cat\/insaferrer\/wp-content\/uploads\/usu2510\/2024\/02\/2.jpg\" alt=\"\" width=\"202\" height=\"151\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">A l\u2019exhibici\u00f3 p\u00fablica hem pogut fer llan\u00e7aments davant les fam\u00edlies, i tamb\u00e9 explicar-los la f\u00edsica del coet mitjan\u00e7ant un p\u00f2ster i una p\u00e0gina web.
