How An Igloo Keeps You Warm
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! |

Cotton T-Shirts and how they're made
How does a simple T-shirt get made? To find out, NPR decided to make one -- and track every step of production. It all started in Mississippi. Or, if you go back far enough, in a seed lab. Take a look at the first two videos of five parts made.

Cotton
How Your T-Shirt Can Make a Difference Did you know that the t-shirt on your back has a major impact on the planet? Producing it took 2,700 liters of water, plus it takes a lot of energy to get it from the cotton fields to your closet. But some of your t-shirt's biggest impacts are in how you care for it. Here's how you can help reduce its effect on the environment. Published on Jan 15, 2013 |

Atoms Explained
Published on Jan 20, 2015 Atoms are very weird. Wrapping your head around exactly how weird, is close to impossible – how can you describe something that is SO removed from humans experience? But then again, they kind of make up everything, so let us try anyways. |

Just how small are atoms?
And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.

Do You Know What Nano Means?
Published on Jan 31, 2013 This video won the 2011 Webby Award for Animation in the Online Film & Video Category. Produced by: Science Alberta Foundation Artist: Daniel Gies http://danielgies.carbonmade.com/ Nano may mean small, very small, but when it comes to making your body work it is big, very big. If your fingernail is about one millimeter thick, and a nanometer is one millionth of a millimeter, you can imagine that there are a lot of nanomaterials making up that small space. |

Liquid stacking in layers works because each liquid has a different density (children can use four different concentrations of salt water and food colouring to achieve the same results)
You'll need: Empty bottle measuring cup dark corn syrup dish washing liquid water (add food coloring) vegetable oil rubbing alcohol (add food coloring) Fill your bottle with water then pour it into a measuring cup, keeping track of how many total oz the bottle held. Then divide the number of liquids you want to stack, into the total amount of oz. That will tell you how many oz of each liquid you should pour into the bottle so that the layers are equal in size. Obviously if you want to have different sized layers, you can. When you add the corn syrup and dish washing liquid be sure to let the liquid drop straight into the container so that it doesnt touch the sides. When you add the water, vegetable oil and alcohol, tilt the bottle and let the liquid run slowly down the sides. If you pour it in too fast, it will mix with the other liquids.
