Just how small are nanomaterials? And what can we do with stuff that small? Today we’ll discuss some special properties of nanomaterials, how some can change at different sizes, and the difference between engineered nanomaterials and ones that occur naturally. We’ll also talk about some of the future research that’s needed on the use of nanomaterials.

Grade 7th on Khan Academy: 7th grade takes much of what you learned in 6th grade to an entirely new level. In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Now that we’ve talked a little bit about how sociology works, it’s time to start exploring some of the ideas of the discipline’s founders. First up: Émile Durkheim. We’ll explain the concept of social facts and how Durkheim framed sociology as a science. We’ll introduce the idea of common consciousness and how Durkheim believed it binds society together. We’ll also talk about Durkheim’s studies on suicide and how he applied his concepts to a specific social problem.

Did you know that many everyday objects around you hide secret features you’ve never noticed? From the button on a seat belt to the hole in a pen cap or even the extra eyelets on your sneakers, these small details all have hidden purposes that make life easier, safer, or just more interesting. In this video, we explore the most surprising hidden purposes of everyday items you use all the time without thinking. Some of these secret features were designed for safety, some for convenience, and others are clever engineering tricks that most people completely miss. Once you see them, you’ll never look at ordinary objects the same way again. If you’ve ever wondered what those tiny symbols, holes, buttons, or shapes are really for, this video will finally give you the answers.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Educational Videos and songs for Kids. In this video we’re going to learn about the birds.

They are so diverse, and there are so many colors and shapes, it's fun to learn about them. For example, this tiny little hummingbird doesn’t look anything like this huge ostrich. And these penguins don’t look much like this peacock with its large fan-shaped tail. Well, they may not look alike, but they’re all birds, and have many things in common.
Birds are oviparous... which as you know, means that they reproduce by laying eggs. The females lay the eggs in nests, in the rocks... or on the ground... And with the heat of their bodies, they incubate the eggs until the little chicks hatch.
Birds don’t have teeth, they have beaks or bills... And these can be very different, depending on what that species of bird feeds on.
They breathe with their lungs, that are connected to... bags full of air... called air sacs... and these help birds to fly. Also, nature, which is very clever, has made their bones hollow, so they weigh very little, and because of this it’s much easier for them to fly.
The skin of birds is covered with feathers: these protect them from the cold and heat. Birds have four limbs, the back ones are legs... and the front ones are wings. Together, the wings and feathers are essential for them to be able to fly... and in some cases... so they can swim.
Birds are terrestrial and most of them can fly. Can you think of any birds that can’t fly? That’s right!!! Penguins and ostriches are two species of birds that cannot fly.
Birds have four types of feathers: those that cover the whole body; flight feathers in the wings that help them to fly; down feathers, which cover the chest and belly and maintain the body at a constant temperature; and tail feathers that help guide the birds’ body like a rudder on a boat.
Birds can be classified into several groups, according to what they eat: herbivores feed on plants and grasses – their beaks are short and strong, and can crush seeds and grains. When they only eat grains, they are called granivores.
Carnivorous birds hunt and eat other animals, using their strong, curved beaks. Within the group of carnivores there are insectivores, that only eat insects, and piscivores that only feed on fish. These birds have pointed beaks that are long and sharp to help them catch the fish. Remember - birds that eat fish are called piscivorous.
The last group - omnivorous birds - includes pigeons and hens, and they eat almost anything.
So remember: birds are oviparous, which means they reproduce by laying eggs; their mouths are beaks or bills and they breathe with their lungs; their skin is covered with feathers; and depending on the food they eat, they can be herbivorous... carnivorous... or omnivorous.
 So, now you know a lot more about birds.

This calculus video tutorial provides a basic introduction into l'hopital's rule. It explains how to use l'hopitals rule to evaluate limits with trig functions, fractions, exponential functions with e^x and natural log functions such as ln(x). To use l'hopital's rule, you need to take the derivative of the numerator and denominator of the fraction any time you have an indeterminate form as a result of direct substitution.
