Building a perfect igloo takes cool science!

If you ever find yourself stranded in the snowy Arctic (or bored in Minecraft), you’re gonna need to know how to build an igloo. But how can building a house made of ice keep you warm? The science behind building an igloo is the same reason that otters and reindeer don't freeze to death!

Regarding use of the word "Eskimo" in this video: We are now aware, thanks to many polite comments from our audience, that this is viewed as a derogatory term among many native peoples of Canada, as well as in some Arctic regions. Several of our references centered on Alaskan natives, among whom this term is more commonly accepted. Additionally, we used the term in reference to native languages, which are more commonly referred to as Eskimo or Eskimo-Inuit, and not the people, but we should have been more clear and sought out another term. We apologize to those we offended, and have learned a lot. We'll do better in the future, as we always aim to do.
It's Okay To Be Smart The collection of languages among the actual people is actually Inuktitut. Just because some groups are chill with it doesn’t mean it should be used by outsiders, just like with any other slur.

Bruh you mad dumb if you think radiation uses convection to transfer heat... radiation is heat transfer between two solid surfaces and convection is heat transfer in a liquid (which air is classified as)
I’m actually Alaskan Native and I am Inupiaq, or Eskimo. The word Igloo actually means “home” but our actual word for it is something along the lines of Igluoq, but. when the Russians came they just made it igloo. also, we actually didn’t live in igloos. we made them for storage of animals that we killed and as a temporary home for hunting during the winter. Our more permanent home during the winter were semi-subterranean homes, which the permafrost in the ground and bones from dead animals helped structure it. i get all of this information from my ancestors and firsthand experience, and also because I worked at the Alaska Native Heritage Center. Message me if you’d like more info
John B Ok, no problem. But what do we call them next year and a few years after that? I don’t know anymore what is going to offend some one. What do you call a person with really dark skin, or light brown skin???? I am afraid to call them anything. My sister and I are white but we often call each other white honkys. Lol
You don’t call Inuit “Eskimos” anymore. It’s derogatory to Inuit people as it means “raw meat eater”. So please don’t use it.
The one thing about Inuit is in their culture they choose their own names when they are older. Calling them a name that they wish not to use for their own people is in fact demeaning.
Virtuitous Vampire okay, first I knew they were not still hunting rabbits or whatever they did hunt, I will use the term Eskimo when I am talking from someone HERE. When I am over THERE, i will use the term Inuit so not to offend anyone.
Most middle class people here do use the term Eskimo, NOT in a offensive way, but that’s just what we call you. Again, we don’t mean anything by it, it’s just the thing we call you. I’m ww2, we called Americans yanks, not as a insult, but that’s just the thing we called them. Sometimes for a little joke, sometimes just second nature. Don’t think British people walk around calling people names and being racist for Christ’s sake lol.
olly bro I’m from Canada and live in an area with Inuit and First Nations people. And from where you live it’s quite obvious your ignorance of Canadian and indigenous cultures are something to be imagined. Yes, it is demeaning. The term “Eskimo” has actually been eliminated from our history books for the last 40 years because of Inuit and indigenous human rights and what is called reconciliation from what the British and colonizers did to Inuit culture. So again, maybe you should LEARN about how other people live and cultures because you are actually not even in modern times. I’m trying to inform you. It’s up to you to actually understand what you say may be offensive to other cultures. Just because you say it doesn’t make it so. Go to Nunavut and say the word “Eskimo” and you will find yourself in a frozen lake. And just so you know Inuit people don’t necessarily even live in igloos anymore. They use modern snowmobiles instead of sled dogs and most eat the same food as everyone else because it’s flown and trucked in. Don’t think that Inuit people are behind the times like they were Neanderthals and hunt walrus, polar bears and fish everyday. They are human beings that still have their culture and food, but now have modern conveniences and technology and actual human rights. When you call them a name they don’t want to be called, you are actually taking those rights from them and further trying to colonize them to what you believe they should be. That’s wrong and disrespectful.
In fact wherever you come from, I would imagine America, it may be hurting their ‘ feelings’. But I’m British, over here in Europe it has no offensive meaning. It is just generally what we call them, because well, that’s the best known word for them. So I’m sorry if it’s offensive over there, but here it’s just the word we use.
Eskimo? Are you living in 1950s? How bout be smart enough to know the difference between archaic racist terminology and and an opportunity to teach folks who are interested in understanding some of our host peoples and their ways? #timetobebetter #acknowledgethegenocide
It's okay to be smart even when you're not smart enough to know that water expands when it freezes and a cubic meter of ice (920ish kg) doesn't weigh the same as a cubic meter of water (1000 kg) 2:54 not that 80 kilos makes it all that much heavier but if you're going to throw in a number make sure it's the right one
Learning how to draw cartoon animals from the farm is not such a difficult task! Weve grown up surrounded by them! Farm animals are everywhere: In blockbuster movies, childs books, greeting cards. their shapes and images are printed in our minds!
In this section, I will show you how to determine what are the physical uniqueness of each animal and how to work with them. Then, you can practice drawing each cartoon character using basic shapes.
You will have the opportunity to make nice illustrations, practice sketching and cartooning using short easy lessons and complete your creation using a drawing software to create vector art if you want to! Cartoon drawing is really fun once you get into it!
Dont be afraid to try until you get it right. This method is really simple, but requires practice and observation. So, sit back and relax. Learn how to draw animals from the farm and start your journey on a good note!
Lets try s few basic characters to get started! :)
A cute turkey to begin with.
In this first tutorial, you can learn how to draw a fun turkey mostly made from small rectangles and large circular shapes. The posture of the character is really interesting. Not only is it easier to draw than a front version, but its also easier to add some perspective (as we can see with the legs). The fact that we just need to draw one wing is also interesting.
Most of these cartoon animals are not filled with complex textures or digital effects. In this case, the subject is filled with plain colors and only a few basic details (inside the tail) were added.
A nice turtle also from a side view.
