The Pixar Theory an Interactive Story, by @97thfloor #pixartheory FORMAÇÃO DOS ELEMENTOS QUÍMICOS É uma teoria aceita que os elementos químicos que formam a matéria existente como nosso planeta e nosso corpo foram produzidos por um processo denominado “Nucleossíntese”. Acredita-se que a nucleossíntese de elementos leves como o Hidrogênio, Hélio, Lítio e Berílio, foram produzidas a partir de um plasma de sub-partículas conhecidas como quarks-glúons, oriundas da grande explosão primordial (Big Bang), quando o universo resfriou abaixo de 10 milhões de graus. Este processo que formou praticamente todo o hidrogênio do universo, que é o elemento mais abundante, é chamado de “Núcleo-gênese”. Sol – Fornalha nuclear de produção de elementos químicos que usa o Hidrogênio como matéria prima. Elementos Químicos Pesados – Formado em explosões de estrelas Supernovas. Estes elementos são produzidos por fusão nuclear nos núcleos das estrelas. Reação de Fusão Nuclear predominante no o Sol que leva a Produção de Hélio Cadeia Nuclear CNO (Carbono e Nitrogênio, Oxigênio). Abundância no Universo
Science Out Loud — MIT+K12 Videos SOL is a YouTube webseries hosted and co-written by MIT students on everything from the physics of skydiving to the biochemistry of farts. With episodes no longer than 5 minutes, these videos take the traditional concepts taught in middle and high school science, engineering, and math (STEM) classes and puts them in a context completely outside the classroom. You won’t find a single equation in these videos - instead, they feature the gamut of hosts and personalities who will take you into labs, rivers, and the sky! Creates (1) 5-min. episodeCook time: ~150 man hours Directions Cast hosts by reviewing <1 min. selfie videos pitches that MIT students submit (~2 weeks).Work one-on-one with cast members to hone their episode ideas after pitch is reviewed and accepted.

We hope you enjoy it! 8 Signs You Are Good In Bed 1. You can dance. Now before all of you start coming at me from every corner of Reddit to cut me off at the pass of my misandry, fedoras clutched in your gnarled fingers and neckbeards springing forth from your quivering underchin like a thousand resilient dandelions, hold on. I don’t mean that those who are incapable of getting past the first two rounds of So You Think You Can Dance are destined to remain shriveled virgins. We don’t all have to be the non-horrific version of Chris Brown when it comes to moving our feet along a dance floor. However, if you are the kind of person who is determined to stay glued against the wall while everyone else is having fun and being silly, I don’t know how your hips would do if naked and horizontal. 2. 3. We all know what that move is. 4. Someone wants to tell you something. 5. You know that “no” is a word with real, important meaning, one that you should listen to unequivocally and respect without exception. 6. 7. 8. (No, I couldn’t.)
EVOLUÇÃO ESTELAR Origem: Wikipédia, a enciclopédia livre. "Linha do tempo" da vida do Sol Em astronomia, evolução estelar é a sequência de mudanças radicais que uma estrela sofre durante seu tempo de vida. Dependendo da massa da estrela, sua vida varia entre alguns milhões de anos (para as mais massivas) até trilhões de anos (para as menos massivas), o que é muito mais do que a idade do universo. A evolução estelar não é estudada pela observação do ciclo de vida de uma única estrela; a maioria das mudanças estelares ocorre tão vagarosamente que só seriam detectáveis depois de muitos e muitos séculos. Nascimento de uma estrela[editar | editar código-fonte] NGC 604, uma região gigante de formação estelar na galáxia Triângulo. Protoestrela[editar | editar código-fonte] A evolução estelar começa com o colapso gravitacional de uma nuvem molecular gigante (NMG), também conhecida como um berçário estelar. Uma NMG colapsada fragmenta-se durante o evento, quebrando-se em pedaços cada vez menores.

Science Helpdesk 6 Myths Everyone Believes about Space (Thanks to Movies) #3. Meteorites Are Hot Let's say a meteorite landed in your yard, right now. You run out there and see the thing sitting in a little crater. Would you touch it? Hell, no. It's never Dave's mom's house that these things crash into, is it? Although we realize this is not the most scientifically accurate of movies, that's the one scene they might have gotten right. The Reality: Said chunks of rock have been in the balls-shriveling cold of space (about 3 degrees above absolute zero) for billions and billions of years. WikipediaLess dangerous than a Hot Pocket. But what about the fireball, then? In fact, the fireball has little to do with the actual physical meteor. WikipediaWith those wriggly tails this is all starting to look like interstellar bukkake. The phenomenon actually does manage to heat up the outer layers of the meteor somewhat, but since those always get blown off on impact, that doesn't really matter. #2. In the red corner: Human. In the blue corner: The Vacuum of Space. #1. Getty
The human digestive system Follow Nat Geo Kids as we take a journey down through the human digestive system to find out where our grub goes! The human digestive system It takes around 24 hours for your dinner to wind its way through the nine-metre-long digestive tract. On its trip, it’s mixed with acids and digestive juices, and squeezed and squelched until all the nutrients that the body needs are absorbed. Let’s follow your food to learn about the brilliant bits of our bodies that make up the human digestive system… Mouth It all starts here! Fast fact: When you swallow, a little flap of cartilage called the epiglottis closes off the windpipe so food doesn’t go down there by mistake. Here, you’ll also find the salivary glands that produce most of the slimy liquid in your mouth. Fast fact: Your salivary glands can produce up to six cups of saliva per day. Oesophagus Also known as the gullet, this 25cm-long tube contracts to shift chewed food down to your stomach. Stomach * Please do not eat a nail. Intestines Liver
Ten Websites for Science Teachers We all know that the web is full of excellent web resources for science teachers and students. However, unless you live on the web, finding the best websites can become quite a challenge. This isn't a "Top Ten" list -- instead, it is a list of websites that I either use on a regular basis or just find interesting. From teaching resources for the nature of science and authentic field journals to wacky videos about numbers, I am sure that you will find something in the following list the works for you! 1) Understanding Science UC Berkeley's Understanding Science website is a "must use" for all science teachers. 2) Field Research Journals The Field Book Project from the National Museum of Natural History and the Smithsonian Institution Archives intends to create a "one stop" archive for field research journals and other documentation. 3) Evolution Berkeley's Understanding Evolution website is the precursor to their Understanding Science efforts. 4) PhET Simulations 5) Earth Exploration
