Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

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.

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

In the final years of the First World War, the Russian Empire was coming to its end. It had been devastated by revolution and finally transformed into the first Communist country in the World. In the years following the Revolution, non-Russian nations that lived under the House of Romanov sought to secure their long-lost independence. One of these was Ukrainе. From 1917 until 1921, the Ukrainians had struggled to build and secure an independent country, fighting against the new regime, against their neighbors in the west, and also among themselves.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Learn colors for Kids | Red Color | Kids Academy

If your kid is at that stage when he is supposed to learn about colors and their names then know that you as a parent or a teacher need to use as many visuals as you can. In fact, it’s an undeniable fact that colors can only be taught through visuals. For starters, you can use a textbook or color pencils to make your little one understand what colors are and how many are there.

Now, of course, the wiser thing to do is to start with the basic colors and focus on them until your kid has it all memorized. You need to teach your child about colors like green, red, yellow, blue. Just let him understand the concept of these basic colors first and then move towards the other ones because when it comes to colors, we all know they are uncountable.

Speaking of teaching colors, let’s suppose you are currently focusing on “red”. Now, in this case, you should be opting for Youtube videos and animations, etc that can teach your child about the color red.

Use different examples, make him watch different videos about the color red and then move towards the point where you test him. Use DIY color books, makeup and sing some songs and rhymes and opt for hand painting to make this learning process fun for your kid.

With a little practice and some hand painting, your kid will surely learn about the color red within no time and once he reaches that stage, you then can move to other colors like blue and green, etc. Moreover, you can even tell about the color red to your child by pointing out his/her favorite dress.

Did you know that different parts of the world are called different things according to the areas properties and wildlife? In this video, you and your kids will learn about several types of habitats that are found all around the globe. You'll learn about the driest places, the wettest places, the coldest places, the tallest places, and more!

First up is grasslands. These areas are full of tall grass and not a lot of trees. You can find them on every continent except Antarctica. Types of grasslands include prairies and savannas. Deserts are next. Even though most people think deserts are always hot, this isn't actually true. Some are very cold. These places are defined as having very little rain or being incredibly dry. Not a lot of animals or plants can survive the desert habitat.

Next you'll learn about a few types of forests: rainforests, temperate forests, and coniferous forests. Rainforests receive rain all year around and are home to more animals than all the other habitats combined!. Temperate forests are ones with trees that lose their leaves in the winter or remain green all year around. Coniferous forests are the forests that have the tallest trees in the world. They can survive extremely cold temperatures.

Speaking of cold, mountain habitats are much cooler because they are so high up. They receive less oxygen. Polar regions are likewise extremely cold. In fact, they're the coldest places on Earth. There are only two polar regions—the Arctic at the top of the globe and the Antarctic at the bottom. Very few types of animals can live here, such as polar bears and whales.

Water habitats exist as well, both freshwater and saltwater bodies are home to habitats like coral reefs and oceans. Freshwater habitats can be found nearly anywhere in the world. Coral reefs are usually around tropical areas of the globe. The ocean is the largest animal habitat in the world. I bet you can guess why! And believe it or not, cities and farms are their own habitats as well.

We hope you and your student(s) enjoyed learning about several types of habitats that we have on Earth! If you want to learn even more, head over to our website and download one of our many free lesson plans about habitats, full of activities, worksheets, and more!

Have you ever heard of the law of inertia? In this Newton's First Law of Motion video for kids, you will learn about why objects either move or don't move. The first law of motion, or the law of inertia, states that objects at rest will remain at rest unless something else moves that object. It also states that an object that is moving will keep moving until something stops it.

When it comes to an object at rest, think of anything around you that isn't moving. A pillow, a book on the desk, or the desk itself. They will stay unmoved unless you, or something else, moves it. As far as objects that are moving, think of a ball in the air. Eventually the ball will fall because of gravity and air resistance. However, if it were in space, it would keep moving forever at the same speed unless it hits something or something hits it.

Speaking of gravity and air resistance, these are two natural forces that affect an object's motion. Another is friction. If you roll something across a flat but uneven surface, that object will eventually stop because of friction. Say, however, you roll something along a flat and even surface, such as perfectly smooth ice. In this case, the object you roll may not stop for a much longer amount of time because there is much less friction to stop its motion.

We hope you and your student(s) enjoyed learning about Newton's first law of motion! If you want to learn even more, head over to our website and download one of our many free lesson plans about the law of inertia, full of activities, worksheets, and more!

This 3D animation explains the hormonal changes during the menstrual cycle. The menstrual cycle begins with menstrual bleeding, marking the follicular phase’s first day. When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the uterus’s thickened lining break down and are shed, and menstrual bleeding occurs.

About this time, the pituitary gland starts sending follicle-stimulating hormone to your ovaries, stimulating the development of 5 to 20 follicles in the ovaries. Each follicle contains an immature egg and produces estrogen. One follicle will soon begin to grow faster than others. This is called the dominant follicle. As the follicle grows, the levels of estrogen in the blood rise significantly. This increase in estrogen begins to inhibit the secretion of the follicle-stimulating hormone. The fall in follicle-stimulating hormone allows smaller follicles to die off. They are, in effect, "starved" of follicle-stimulating hormone.

The increasing amount of estrogen in your body also ensures that the lining of your womb thickens with nutrients and blood. This is so that if you do get pregnant, the fertilized egg will have everything it needs to grow.

The ovulatory phase begins with a rise in the levels of luteinizing hormone and follicle-stimulating hormone. The surge in the luteinizing hormone triggers one of the most prominent follicles to pop open and release its egg, which heads into the fallopian tube and starts its journey toward the uterus. Ovulation usually occurs 16 to 32 hours after the beginning of the surge, around day 14 of the menstrual cycle.

During the luteal phase, the levels of the luteinizing hormone and follicle-stimulating hormone decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces estrogen and progesterone, which cause the lining of the uterus to thicken even more. If an egg is fertilized, progesterone supports early pregnancy. But if no fertilization occurs, the corpus luteum will break down between 9 and 11 days after ovulation. This results in a drop in estrogen and progesterone levels, bringing us back to the first stage of menstruation if no pregnancy has occurred.
