Moles (in chemistry) are really clever and useful. The definition involves a really big number called Avogadro's Number and on its own is really unhelpful when trying to understand what the Mole is actually for! The best way to get your head around this unit (Mol) is to look at the problem that is solves. Along the way you'll find out about Atomic Mass Units, isotopes and some dodgy chemical equations!

Title: Comparing Fractions to 1 - Fast And Easy Math Learning Videos
In this lesson, you will learn when a fraction is less than one whole unit, equal to one whole unit, or more than one whole unit. A fraction equals one whole unit when the numerator and denominator are the same. This example shows us that two-thirds does not equal one. The numerator and denominator are not the same.
Here's another example of a fraction that does not equal one. Five-thirds does not equal one. The numerator and denominator are not the same.
Now let's look at a fraction that does equal one whole unit. Three-thirds equals one. The numerator and denominator are the same.
Here's another example of a fraction that is equal to one. Six-sixths equals one. The numerator and denominator are the same.
Now let's take look at fractions that are less than one and more than one. Four-sixths is less than one. A fraction is less than one when the numerator is less than the denominator.
Here's an example of a fraction that is more than one. Fifteen-sixths is more than one. A fraction is more than one when the numerator is more than the denominator.
Now try a few problems on your own. To solve this problem, you must click on the correct answer, like this.
The correct answer is less than. One-third is less than 1. For the problems that follow, click on the correct answer.

Title: Dividing Fractions
You know that the multiplication of both whole numbers and fractions can be represented using an array that looks like this. This example shows four-fifths multiplied by two-thirds.
The product of multiplying the fractions is eight-fifteenths.
You also know that division is just another way of writing multiplication when one of the factors is unknown. That’s easy to see using this array. Let’s assume that you know the total size of the array, which is eight-fifteenths, and you know one of the factors in the multiplication, four-fifths.
But you don’t know the other factor, which we’ll now call X.
X is the number you need to multiply by four-fifths to get eight-fifteenths.
We can represent this situation with two different number sentences.
The first number sentence is written as multiplication. We know that four-fifths is multiplied by some number on this side called X.
And the result is eight-fifteenths.
We can also describe exactly the same situation with a division number sentence like this.
We know that we have eight-fifteenths, which is divided by four-fifths.
But we don’t know the length of this side of the array, which is the value for X.
So, these equations tell us exactly the same thing because they represent the same situation shown by the array.
The X in both equations represents the same number – it’s the missing value for the length of one side of the array.
While this array is helpful in seeing what a division problem represents, it’s not very helpful in finding out the number we need on this side, because we don’t know how many parts to divide each whole unit into. So how do we find this number? The best way is to use what we know about algebraic reasoning, using these two equations to describe the array.
We’ll start by finding the value of X in the multiplication equation.
This will help us later in understanding how to solve the division equation.
You know that you can multiply both sides of an equation by the same number and it doesn’t change the equation. We can use this to our advantage if we choose the right number to multiply by. We want a number that will give us one X instead of four-fifths X on the left side of the equation.
You know that multiplying any number by its reciprocal gives you 1. Let’s multiply fourth-fifths by its reciprocal like this.
Five-fourths times four-fifths is one, so the left side of the equation now becomes 1 times X, which we write as just X. You also know that if you multiply one side of an equation by a number you have to multiply the other side by the same number.
So, we multiply the right side of the equation by five-fourths.
When we multiply, we get forty-sixtieths.
We can divide both terms by 20, to see that X equals two thirds.
When we compare this to the multiplication problem we started with, we see that two-thirds is the correct answer, because two-thirds times fourth-fifths is indeed eight-fifteenths.
But how does this help us understand how to divide fractions? It’s actually very simple. Let’s look at these two statements from the equations.
Remember that X represents the same number in both equations. It’s the length of this line in the aray.
The equation on the right says you can find X by dividing eight-fifteenths by four-fifths. The eqution on the left says you can find X by multiplying eight-fifteenths by the reciprocal of four-fifths.
Using what you already know about algebra, you can prove that this same approach always works, but we won’t go through that proof here. It means that dividing any number by a fraction and multiplying that number by its reciprocal gives you the same result.
We’ll just look at a couple of examples to verify that this works.
We’ll start with this multiplication statement. Three-fourths times five-eighths equals fifteen-thirty-seconds.

In this math lesson, you will learn how to tell time on an analog clock. In this lesson, we will focus on reading the short or hour hand and the long minute hand.
We will learn three easy steps to tell time.
Start at the small hand
Write two dots
Read the large hand.
Alfred Wegener developed the theory of Continental Drift. It states that at one time the continents were at one time one large land mass that broke apart and the continents drifted away from one another. The continents move away at a rate of about 10 cm per year.

The endomembrane system of eukaryotic cells is a transportation system inside plant and animal cells.
It consists of the nuclear membrane, rough and smooth ER the Golgi apparatus, and vesicles.
Ribosomes which are protein factories of the cell can be found on the rough er these ribosomes create proteins and then transfer these proteins into the ER where they undergo modifications, such as folding. These modified proteins may be absorbed into the membrane of the Er or packaged into a vesicle that may travel to the Golgi apparatus.

Learn how to create a dichotomous key. A dichotomous key is a method to identify objects like animals, rocks, trees, plants, and many other objects. In this video, I use monsters in order to show you how to create a simple dichotomous key. Dichotomous means two parts so the key uses two questions at each step. There are different types of dichotomous keys but in this video I show you how to make a simple key.
