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.

Hello friends! Welcome to a new Happy Learning video.
Have you ever wondered how plants feed? To answer this question, we need to understand photosynthesis!

Photosynthesis is a process in which plants make their own food to be able to grow and develop. In order to perform photosynthesis, they need various elements: sunlight, carbon dioxide, obtained from air and water. They also need chlorophyll, which is a green substance that all plants have, and is fundamental for performing photosynthesis, since it could not happen without it. By the way! chlorophyll is what gives all plants their green colour!

But how does photosynthesis take place?
Look at this plant. As you can see, its roots are anchored to the ground, and through them, the plant absorbs water and minerals in the soil.
Water with minerals are transported up the stem, reaching the leaves. The leaves are full of tiny pores, called stomata, which absorb carbon dioxide that air in their surrounding contains.
All this containing water, minerals and carbon dioxide is called raw sap.

Now it’s chlorophyll’s turn!
The chlorophyll in the leaves has all the necessary ingredients for photosynthesis to take place and when it receives sunlight, the process begins by transforming the raw sap into elaborated sap, which also circulates around the plant and works as food.
All plants feed from elaborated sap, and they store it in their roots, like a carrot. Or in their fruit, like an apple or a pear.

Now we know how photosynthesis takes place but…
Why is it so important?

Without plants, there would not be life on Earth, we wouldn't have oxygen to breathe or food to feed on. You already know that herbivores eat plants and carnivores, eat herbivores. Plants are fundamental for the food chain. And they are also fundamental for our respiration. Actually, when humans breathe, we turn oxygen into carbon dioxide, quite the opposite of when plants perform photosynthesis. A curious fact you need to know is that, at night, because plants don’t have sunlight to photosynthesise, they breathe like humans do. They take in oxygen and release carbon dioxide. Remember that!

And one last thing so you understand the importance of photosynthesis. When plants absorb dirty and contaminated gases, they transform them into pure air, into oxygen! This way, they clean the atmosphere and all nature. Plants are the best solution to fight against contamination, don’t you think?

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!

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

World history on Khan Academy: Called the Great War (before World War II came about), World War I was the bloody wake-up call that humanity was entering into a new stage of civilization. Really the defining conflict that took Europe from 19th Century Imperial states that saw heroism in war into a modern shape. Unfortunately, it had to go through World War II as well (that some would argue was due to imbalances created by World War I).
