<video:title>Earth's Atmosphere – The 5 layers explained</video:title>
<video:thumbnail_loc>https://curiouskidslab.net/thumbs/atmosphere.jpg</video:thumbnail_loc>
<video:description>Earth's atmosphere is the layer of air that surrounds our planet like an invisible blanket. It has five layers: the troposphere, where we live and where clouds form, then the stratosphere, home of the ozone layer, the mesosphere, the thermosphere and the exosphere, which fades into outer space. The atmosphere gives us oxygen to breathe and protects us from the Sun's harmful rays.</video:description>

<video:description>الغلاف الجوي هو طبقة الهواء التي تحيط بكوكبنا مثل بطانية غير مرئية. يتكوّن من خمس طبقات: التروبوسفير حيث نعيش وتتكوّن السحب، ثم الستراتوسفير الذي يضم طبقة الأوزون، ثم الميزوسفير والثرموسفير والإكسوسفير التي تتلاشى في الفضاء. يمنحنا الغلاف الجوي الأكسجين الذي نتنفسه ويحمينا من أشعة الشمس الضارة.</video:description>

<video:title>The Water Cycle – Follow Droppy on a big trip</video:title>
<video:thumbnail_loc>https://curiouskidslab.net/thumbs/water-cycle.jpg</video:thumbnail_loc>
<video:description>The water cycle is the never-ending journey of water around the Earth. The Sun warms the sea and water rises as invisible vapor (evaporation); high in the cold sky it turns into tiny drops that make clouds (condensation); the drops fall as rain or snow (precipitation); then streams and rivers carry the water back to the sea (collection). The same water has been travelling this way for millions of years.</video:description>

Le Soleil réchauffe la mer et l'eau monte sous forme de vapeur invisible (évaporation) ; dans le ciel froid, elle se transforme en minuscules gouttes qui forment les nuages (condensation) ; les gouttes retombent en pluie ou en neige (précipitations) ; puis les ruisseaux et les rivières ramènent l'eau à la mer (ruissellement). C'est la même eau qui voyage ainsi depuis des millions d'années.</video:description>

<video:description>دورة الماء هي رحلة الماء التي لا تنتهي حول الأرض. تُدفئ الشمس البحر فيصعد الماء بخارًا غير مرئي (التبخّر)، وفي السماء الباردة يتحوّل إلى قطرات صغيرة جدًا تكوّن السحب (التكاثف)، ثم تسقط القطرات مطرًا أو ثلجًا (الهطول)، وبعدها تعيد الجداول والأنهار الماء إلى البحر (التجمّع). إنه الماء نفسه الذي يسافر بهذه الطريقة منذ ملايين السنين.</video:description>

<video:description>We have day and night because the Earth spins like a giant spinning top. The Sun always shines, but it can only light up one side of the Earth at a time: that side has daytime, and the other side has nighttime. One full spin takes 24 hours, so every place on Earth gets one day and one night.</video:description>

Un tour complet dure 24 heures : chaque endroit de la Terre a donc un jour et une nuit.</video:description>

<video:title>Volcanoes – Why do volcanoes erupt?</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/4daJJCjFjx8/maxresdefault.jpg</video:thumbnail_loc>
<video:description>A volcano erupts when magma, hot melted rock from deep under our feet, is pushed up by gas bubbles, a bit like a shaken bottle of soda. When it comes out, magma is called lava: it is about ten times hotter than boiling water. Lava cools down into brand new rock, building mountains and even islands. Most volcanoes are asleep, and scientists called volcanologists watch them to keep everyone safe.</video:description>

<video:description>Un volcan entre en éruption quand le magma, de la roche fondue très chaude venue des profondeurs, est poussé vers le haut par des bulles de gaz, un peu comme dans une bouteille de soda secouée. En sortant, le magma s'appelle la lave : elle est environ dix fois plus chaude que l'eau bouillante. En refroidissant, la lave devient une roche toute neuve qui construit des montagnes et même des îles. La plupart des volcans sont endormis, et des scientifiques, les volcanologues, les surveillent pour protéger tout le monde.</video:description>

<video:description>يثور البركان عندما تدفع فقاعاتُ الغاز الصهارةَ، وهي صخور ذائبة شديدة الحرارة تأتي من أعماق الأرض، إلى الأعلى، تمامًا مثل قارورة مشروب غازي مرجوجة. عندما تخرج الصهارة تُسمّى حممًا، وهي أسخن من الماء المغلي بنحو عشر مرات. وعندما تبرد الحمم تصبح صخرًا جديدًا يبني الجبال وحتى الجزر. معظم البراكين نائمة، ويراقبها علماء البراكين ليحموا الجميع.</video:description>

<video:title>States of Matter – Solid, liquid or gas?</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/1rD9EccD-v8/maxresdefault.jpg</video:thumbnail_loc>
<video:description>Matter is everything around us, and it comes in three main states. Solids, like ice or a stone, keep their own shape. Liquids, like water or juice, flow and take the shape of their container. Gases, like air or steam, spread out to fill all the space they can. Heat and cold make matter change state: heat turns ice into water and water into steam, and cold turns water back into ice.</video:description>

<video:thumbnail_loc>https://i.ytimg.com/vi/1rD9EccD-v8/maxresdefault.jpg</video:thumbnail_loc>
<video:description>La matière, c'est tout ce qui nous entoure, et elle existe sous trois états principaux. Les solides, comme la glace ou une pierre, gardent leur forme. Les liquides, comme l'eau ou le jus, coulent et prennent la forme de leur récipient. Les gaz, comme l'air ou la vapeur, s'étalent pour remplir tout l'espace. La chaleur et le froid font changer la matière d'état : la chaleur transforme la glace en eau et l'eau en vapeur, et le froid retransforme l'eau en glace.</video:description>

<video:title>حالات المادة – صلب أم سائل أم غاز؟</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/1rD9EccD-v8/maxresdefault.jpg</video:thumbnail_loc>
<video:description>المادة هي كل ما يحيط بنا، ولها ثلاث حالات رئيسية. المواد الصلبة، مثل الجليد أو الحجر، تحافظ على شكلها. والسوائل، مثل الماء أو العصير، تسيل وتأخذ شكل الإناء الذي توضع فيه. أما الغازات، مثل الهواء أو البخار، فتنتشر لتملأ كل المكان. الحرارة والبرد يغيّران حالة المادة: الحرارة تحوّل الجليد إلى ماء والماء إلى بخار، والبرد يعيد الماء إلى جليد.</video:description>

<video:title>Life Cycle of a Butterfly – Egg, caterpillar, chrysalis, butterfly</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/kog__GDi7Ho/maxresdefault.jpg</video:thumbnail_loc>
<video:description>A butterfly's life has four stages. First, a mother butterfly lays a tiny egg on a leaf. A few days later, a little caterpillar comes out of the egg: it eats leaves all day long, grows very fast and changes its skin when it gets too tight. Then the caterpillar hangs upside down and wraps itself in a hard shell called a chrysalis. Inside, its whole body changes: this big change is called metamorphosis. Finally the chrysalis opens and a butterfly comes out, dries its wings in the sun and flies away to the flowers. One day it lays eggs, and the life cycle starts all over again.</video:description>

<video:title>Le cycle de vie du papillon – Œuf, chenille, chrysalide, papillon</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/kog__GDi7Ho/maxresdefault.jpg</video:thumbnail_loc>
<video:description>La vie d'un papillon compte quatre étapes. D'abord, une maman papillon pond un tout petit œuf sur une feuille. Quelques jours plus tard, une petite chenille sort de l'œuf : elle mange des feuilles toute la journée, grandit très vite et change de peau quand elle devient trop serrée. Ensuite, la chenille se suspend la tête en bas et s'enferme dans une coque dure appelée chrysalide. À l'intérieur, tout son corps se transforme : ce grand changement s'appelle la métamorphose. Enfin, la chrysalide s'ouvre et un papillon en sort, fait sécher ses ailes au soleil et s'envole vers les fleurs. Un jour, il pond à son tour des œufs, et le cycle de vie recommence.</video:description>

<video:title>دورة حياة الفراشة – بيضة، يرقة، شرنقة، فراشة</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/kog__GDi7Ho/maxresdefault.jpg</video:thumbnail_loc>
<video:description>تمرّ حياة الفراشة بأربع مراحل. أولًا، تضع أمّ الفراشة بيضة صغيرة على ورقة شجر. وبعد بضعة أيام، تخرج من البيضة يرقة صغيرة: تأكل الأوراق طوال اليوم، وتكبر بسرعة كبيرة، وتغيّر جلدها عندما يصبح ضيّقًا عليها. ثم تتدلّى اليرقة ورأسها إلى الأسفل وتلفّ نفسها داخل غلاف صلب يسمّى الشرنقة. وفي داخلها يتغيّر جسمها كلّه: هذا التغيّر الكبير يسمّى التحوّل. وأخيرًا تنفتح الشرنقة وتخرج منها فراشة، تجفّف جناحيها في الشمس ثم تطير نحو الأزهار. وفي يوم من الأيام تضع هي أيضًا بيضًا، فتبدأ دورة الحياة من جديد.</video:description>

<video:title>Phases of the Moon – Why does the Moon change shape?</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/XXauJPIDeAs/maxresdefault.jpg</video:thumbnail_loc>
<video:description>The Moon is always a big round ball: it never really changes shape. It does not make its own light; the Sun lights up one half of it. As the Moon travels around the Earth, a trip that takes about one month, we see more or less of its bright side. At new moon the bright side faces away from us. A few days later we see a thin crescent, then half of the bright side at first quarter, and finally the whole bright side: a full moon. These different shapes are called the phases of the Moon, and then they start all over again.</video:description>

<video:thumbnail_loc>https://i.ytimg.com/vi/XXauJPIDeAs/maxresdefault.jpg</video:thumbnail_loc>
<video:description>La Lune est toujours une grosse boule ronde : elle ne change jamais vraiment de forme. Elle ne fabrique pas sa propre lumière ; c'est le Soleil qui en éclaire une moitié. Pendant que la Lune fait le tour de la Terre, un voyage qui dure environ un mois, nous voyons une partie plus ou moins grande de son côté éclairé. À la nouvelle lune, le côté éclairé est tourné de l'autre côté. Quelques jours plus tard, on voit un fin croissant, puis la moitié du côté éclairé au premier quartier, et enfin tout le côté éclairé : c'est la pleine lune. Ces différentes formes s'appellent les phases de la Lune, et ensuite tout recommence.</video:description>

<video:thumbnail_loc>https://i.ytimg.com/vi/XXauJPIDeAs/maxresdefault.jpg</video:thumbnail_loc>
<video:description>القمر دائمًا كرة كبيرة مستديرة، ولا يتغيّر شكله حقًّا. وهو لا يصنع ضوءه بنفسه، بل تضيء الشمس نصفه. وبينما يدور القمر حول الأرض في رحلة تستغرق شهرًا تقريبًا، نرى جزءًا أكبر أو أصغر من جانبه المضيء. في المحاق يكون الجانب المضيء متّجهًا بعيدًا عنّا. وبعد بضعة أيام نرى هلالًا رفيعًا، ثم نصف الجانب المضيء في التربيع الأول، وأخيرًا الجانب المضيء كلّه: إنه البدر. هذه الأشكال المختلفة تسمّى أطوار القمر، ثم تبدأ من جديد.</video:description>

<video:title>Magnets – Push and pull</video:title>
<video:thumbnail_loc>https://i.ytimg.com/vi/3bH-upH350M/maxresdefault.jpg</video:thumbnail_loc>
<video:description>A magnet can pull some things toward it without touching them: this invisible pull is called a magnetic force. Magnets pull things made of iron or steel, like paper clips, nails and a fridge door, but not wood, plastic or paper, and not every metal: a soda can does not stick. Every magnet has two ends called poles, a north pole and a south pole. Opposite poles attract, and the same poles push each other away. Pushes and pulls are forces, and forces can make things move. Magnets can even work through paper.</video:description>

<video:title>Les aimants – Attirer et repousser</video:title>

<video:description>Un aimant peut attirer certains objets vers lui sans les toucher : cette attraction invisible s'appelle la force magnétique. Les aimants attirent les objets en fer ou en acier, comme les trombones, les clous et la porte du frigo, mais pas le bois, le plastique ou le papier, et pas tous les métaux : une canette ne colle pas. Chaque aimant a deux bouts appelés pôles, un pôle nord et un pôle sud. Les pôles opposés s'attirent, et les mêmes pôles se repoussent. Pousser et tirer sont des forces, et les forces peuvent faire bouger les objets. Les aimants agissent même à travers le papier.</video:description>

<video:title>المغناطيس – الجذب والدفع</video:title>

<video:description>يستطيع المغناطيس أن يجذب بعض الأشياء نحوه من دون أن يلمسها: هذا الجذب الخفي يسمّى القوة المغناطيسية. يجذب المغناطيس الأشياء المصنوعة من الحديد أو الفولاذ، مثل مشابك الورق والمسامير وباب الثلاجة، لكنه لا يجذب الخشب أو البلاستيك أو الورق، ولا يجذب كل المعادن: علبة المشروب الغازي لا تلتصق به. لكل مغناطيس طرفان يسمّيان القطبين: القطب الشمالي والقطب الجنوبي. القطبان المختلفان يتجاذبان، والقطبان المتشابهان يتنافران. الدفع والجذب قوى، والقوى تستطيع أن تحرّك الأشياء. ويعمل المغناطيس حتى من خلال الورق.</video:description>
