Seulement le soleil est l\u2019\u00e9toile la plus proche de la Terre, ainsi elle nous para\u00eet beaucoup plus grande. Le soleil se trouve au centre de notre syst\u00e8me solaire. Autour de lui gravitent, dans l\u2019ordre, Mercure, V\u00e9nus, la Terre, Mars, Jupiter, Saturne, Uranus et Neptune. On dit qu\u2019il s\u2019agit d\u2019un syst\u00e8me <\/span><b>h\u00e9liocentrique<\/b><span style=\"font-weight: 400\">. Le soleil est une source primaire, ainsi il produit la lumi\u00e8re qu\u2019il renvoie. Les rayonnements solaires transmettent \u00e0 la Terre de la <\/span><b>chaleur <\/b><span style=\"font-weight: 400\">(\u00e9nergie thermique) et de la <\/span><b>lumi\u00e8re <\/b><span style=\"font-weight: 400\">(\u00e9nergie lumineuse).\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">La <\/span><b>Terre <\/b><span style=\"font-weight: 400\">est, quant \u00e0 elle, une <\/span><b>plan\u00e8te <\/b><span style=\"font-weight: 400\">c&rsquo;est-\u00e0-dire un corps c\u00e9leste orbitant autour d\u2019une \u00e9toile. Le soleil est 109 fois plus grand que la Terre. Cette plan\u00e8te est inclin\u00e9e \u00e0 environ <\/span><b>23\u201926 <\/b><span style=\"font-weight: 400\">en moyenne, ainsi la quantit\u00e9 de rayonnement lumineux atteignant la Terre \u00e0 un endroit fixe \u00e0 tout moment de l\u2019ann\u00e9e n\u2019est pas la m\u00eame. C\u2019est cet axe qui provoque ce qu\u2019on appelle les <\/span><b>saisons<\/b><span style=\"font-weight: 400\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">On dit qu\u2019une journ\u00e9e dure <\/span><b>24 heures<\/b><span style=\"font-weight: 400\">. En effet, si l\u2019on se place au niveau du Soleil, la Terre effectue une rotation sur elle-m\u00eame en 24 heures. Cependant, par rapport aux \u00e9toiles, la terre effectue cette rotation en 23 heures et 56 minutes, c\u2019est ce qu\u2019on appelle le <\/span><b>jour sid\u00e9ral<\/b><span style=\"font-weight: 400\">. Si on regarde le p\u00f4le Nord, la Terre tourne dans le<\/span><b> sens inverse des aiguilles d\u2019une montre (de l\u2019Est vers l\u2019Ouest)<\/b><span style=\"font-weight: 400\">. Elle effectue sa rotation sur un axe imaginaire allant du p\u00f4le Nord au p\u00f4le Sud en passant par le centre de la Terre. On dit que le Soleil se l\u00e8ve approximativement \u00e0 l\u2019Est et se couche approximativement \u00e0 l\u2019Ouest. En effet, d\u2019un point de vue terrestre on peut voir le soleil se lever \u00e0 l\u2019Est et se coucher \u00e0 l\u2019Ouest mais c\u2019est bien en effet la Terre qui tourne sur elle-m\u00eame. La rotation de la Terre sur elle-m\u00eame et cette alternance jour\/nuit provoque ce que l\u2019on appelle les <\/span><b>fuseaux horaires<\/b><span style=\"font-weight: 400\">, visibles sur un planisph\u00e8re par exemple.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">La partie de la Terre non \u00e9clair\u00e9e par le Soleil est \u00e9clair\u00e9e par la <\/span><b>Lune<\/b><span style=\"font-weight: 400\"> mais en r\u00e9alit\u00e9 la Lune n\u2019\u00e9met pas sa propre lumi\u00e8re. Il s\u2019agit des rayons du Soleil qui r\u00e9fl\u00e9chissent aussi la surface de la Lune qui r\u00e9fl\u00e9chit elle-m\u00eame cette lumi\u00e8re sur la Terre lors de la phase de nuit.<\/span><\/p>\n<h2><span style=\"color: #003366\">S\u00e9quence possible\u00a0<\/span><\/h2>\n<p>Voici une s\u00e9quence que nous avons imagin\u00e9 pour des \u00e9l\u00e8ves en classe de CM1\/CM2.<\/p>\n<p><span style=\"font-weight: 400\">La s\u00e9quence est compos\u00e9e de six s\u00e9ances dont la sixi\u00e8me est une s\u00e9ance d\u2019\u00e9valuation sommative. Cette s\u00e9quence pourra \u00eatre \u00e9tudi\u00e9e apr\u00e8s avoir vu la place de la Terre dans le syst\u00e8me solaire (pr\u00e9-requis). L\u2019objectif est que les \u00e9l\u00e8ves soient capables de comprendre les mouvements de la Terre permettant d\u2019expliquer l\u2019alternance jour-nuit et une premi\u00e8re approche des saisons.\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-8810 aligncenter\" src=\"http:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/1.png\" alt=\"\" width=\"697\" height=\"683\" srcset=\"https:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/1.png 767w, https:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/1-300x294.png 300w\" sizes=\"auto, (max-width: 697px) 100vw, 697px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-8811 aligncenter\" src=\"http:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/2.png\" alt=\"\" width=\"693\" height=\"1004\" srcset=\"https:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/2.png 612w, https:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/2-207x300.png 207w\" sizes=\"auto, (max-width: 693px) 100vw, 693px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-8812 aligncenter\" src=\"http:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/3.png\" alt=\"\" width=\"672\" height=\"921\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-8813 aligncenter\" src=\"http:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/4.png\" alt=\"\" width=\"672\" height=\"778\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-8814 aligncenter\" src=\"http:\/\/blog.espe-bretagne.fr\/prodm1vannes\/wp-content\/uploads\/2021\/03\/5.png\" alt=\"\" width=\"675\" height=\"872\" \/><\/p>\n<h2><span style=\"color: #003366\">Conseils :\u00a0<\/span><\/h2>\n<p>Attention, notre maquette est bien une <strong>mod\u00e9lisation<\/strong> de l&rsquo;alternance jour-nuit, elle a des avantages mais aussi des inconv\u00e9nients.
