Per aquest motiu, hem optat per fer els nostres propis cristalls.<\/p>\n<p style=\"text-align: justify;\">Durant algunes classes, hem anat al laboratori per aprendre i treballar amb els cristalls.<\/p>\n<p style=\"text-align: justify;\">Un cristall \u00e9s una forma s\u00f2lida, on els \u00e0toms, mol\u00e8cules o ions, estan empaquetats de manera ordenada i amb patrons de repetici\u00f3 que s&#8217;estenen en les tres dimensions espacials.<\/p>\n<p style=\"text-align: justify;\">En aquest cas, la cristal\u00b7litzaci\u00f3 es produeix perqu\u00e8 la dissoluci\u00f3 queda saturada a altes temperatures. Es posa molta concentraci\u00f3 de fosfat monoam\u00f2nic (ADP) en un recipient amb aigua calenta. Quan la dissoluci\u00f3 es refreda queda sobresaturada, formant cristalls.<\/p>\n<p style=\"text-align: justify;\">Vam marcar-nos com a objectius:<\/p>\n<ul style=\"text-align: justify;\">\n<li>Aprendre de manera te\u00f2rica i did\u00e0ctica que s\u00f3n els cristalls.<\/li>\n<li>Seguir el proc\u00e9s de la cristal\u00b7litzaci\u00f3 en persona.<\/li>\n<li>Entendre com funciona la solubilitat.<\/li>\n<li>Tenir un record f\u00edsic del tema dels cristalls.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Com a resultat final, hem obtingut diferents cristalls d\u2019ADP de diferents mides i colors. La gran majoria d\u2019aquests van sortir b\u00e9, per\u00f2 en un dels cristalls vam ficar massa fosfat monoam\u00f2nic i aix\u00f2 va provocar que s\u2019acumul\u00e9s en el recipient i no va poder cristal\u00b7litzar com vol\u00edem, ja que va precipitar massa de pressa.<\/p>\n<p style=\"text-align: justify;\">De tota manera, tots els alumnes hem pogut obtenir un cristall i hem gaudit de l&#8217;experi\u00e8ncia.<\/p>\n<p><strong><em>Alumnat F\u00edsica i Qu\u00edmica 4tESO<\/em><\/strong><\/p>\n<p><iframe loading=\"lazy\" title=\"Cristalls\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/95xF5b0woiQ?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><a href=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8428.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-12209 alignleft\" src=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8428-1024x788.jpg\" alt=\"\" width=\"346\" height=\"266\" srcset=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8428-1024x788.jpg 1024w, https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8428-300x231.jpg 300w, https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8428-768x591.jpg 768w\" sizes=\"auto, (max-width: 346px) 100vw, 346px\" \/><\/a><a href=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-12210 alignright\" src=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426-1024x768.jpg\" alt=\"\" width=\"333\" height=\"250\" srcset=\"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426-1024x768.jpg 1024w, https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426-300x225.jpg 300w, https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426-768x576.jpg 768w, https:\/\/agora.xtec.cat\/ieselsplanells\/wp-content\/uploads\/usu1160\/2021\/03\/IMG_8426-200x150.jpg 200w\" sizes=\"auto, (max-width: 333px) 100vw, 333px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Experiment de cristal\u00b7litzaci\u00f3 de l&#8217;alumnat de 4t d&#8217;ESO de l&#8217;optativa de F\u00edsica i Qu\u00edmica.&hellip;  <a href=\"https:\/\/agora.xtec.cat\/ieselsplanells\/general\/cristallitzem-adp\/\" title=\"Read Cristal\u00b7litzem ADP\">Llegeix m\u00e9s\u00bb<\/a><\/p>\n","protected":false},"author":1,"featured_media":12208,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"footnotes":""},"categories":[454,1,29],"tags":[441,447,446],"class_list":["post-12205","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-curs-2020-2021","category-general","category-portada","tag-2020-2021","tag-experiments","tag-fisica-i-quimica"],"post_mailing_queue_ids":[],"_links":{"self":[{"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/posts\/12205","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/comments?post=12205"}],"version-history":[{"count":3,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/posts\/12205\/revisions"}],"predecessor-version":[{"id":12213,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/posts\/12205\/revisions\/12213"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/media\/12208"}],"wp:attachment":[{"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/media?parent=12205"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/categories?post=12205"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agora.xtec.cat\/ieselsplanells\/wp-json\/wp\/v2\/tags?post=12205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
