Sometimes it is much easier to work out an equation if your numbers are in decimal form instead of fractions. This is especially useful if you are using a basic calculator.Check out this tutorial and learn exactly how to convert fractions into decimals in math class.So, if you are new to conversions, or simply need a refresher, have a look at this informative video and start rockin' your math tests.

This video illustrates how to do a "free fall" experiment to understand orbits. Here are the following steps:

Are you "just not a math person"? Hogwash. Everyone seems to think that at one point in their life. With a little practice and study, math will become more and more easy to understand. Start your journey towards become a "math person" with help from this video, which teaches how to graph a linear equation using slope-intercept form.

In this video from Dr. Carlson, users are shown how to witness the effects of the relationship between temperature and matter firsthand, using light-sticks. For the experiment, users need 3 beakers (or vessels of the sort,) and 3 light-sticks of the same color, shape, and light. To test the range, each beaker must correspond to one of the following states: room temperature, ice-water, or boiling water. Deposit a stick in each of them and observe for two minutes. Thus, one will see how the atoms...

In this how to video, you will learn about Chemiluminescence and the oxidation of Luminol. The first solution is Luminol and NaOH. The second is K3 and H202. Luminol is used to detect blood in crime scenes. It reacts with Iron in Hemoglobin. As you can see in the example, it illuminates the chemicals in the dark. This is why it is very useful for crime scenes. It can be used even if the blood is not visible with day light. Thus, it is an invaluable chemical in the name of science and...

Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not....

This video is about how to splint a broken bone in an emergency situation. You will need two sticks. For a broken arm you will place the sticks on the front and back of the arm. Now tear a shirt, piece of clothing or other cloth into strips. Tightly wrap the strips of cloth around the arm and the sticks on either side of the fracture - near the elbow and near the wrist. If you have a severe break where part of the bone is sticking out through the skin, take two strips of cloth and wrap one...

Calculating probablities can be used to help us make decision. PatrickJMT explains how to calculate probability in an "either A or not A" scenario. The probability of A plus the probability of not A is equal to one. Therefore, the probability of A is equal to one minus the probability of not A ; P(A)= 1 - P(not A). The probability of a major earthquake in San Francisco over a period of time is used as an example. The probablity of an earthquake of a magnitude of 7.5 or greater in San Francisco...

In this Education video tutorial you will learn how to do a cool volcano experiment at home. You will need a bottle of tonic water, mentos and some paper. Wrap the paper around the mentos to make a tube for releasing the mentos in to the bottle. Now pour about half a packet of mentos in to the paper tube and prevent them from falling off with your finger. Now open the bottle of tonic water and release all the mentos from the paper tube in to the bottle all at once. The tonic water will gush out...

In this how to video, you will learn how to make a rain gauge. First, you will need a 2 liter bottle to collect the rain. You will also need scissors, a ruler, and a permanent marker. First, take the bottle cap off of the soda bottle. Next, cut the top of the bottle off. Now, collect some pebbles and put it at the bottom of the bottle. This will keep the bottle in place. Pace the top of the bottle on top to use a as a funnel. Now, take a ruler and measure 7 cm high on the rain gauge. ...

Ahh, the thesis statement. Two words I haven't read or heard since I was in college. Two words that tortured me for a good year in high school. Anyway, this video tutorial gives you an understanding of what a thesis statement is and how to write a great one. Pay attention and good luck!

From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps. With this free math tutorial, you'll learn how to change top-heavy improper fractions into mixed numbers.

Paraphrasing is a useful tool you can use to avoid plagiarism, and still use expert facts. In this tutorial, learn how to quote your research in an essay properly and avoid making illegal mistakes.

The fastest and easiest way to improve your handwriting is to learn to hold your pencil properly. A lot of people bypass this seemingly small step and then wonder why their writing looks like chicken scratch. This video will show you exactly how to hold your pen or pencil for the best writing results. This is especially helpful for teachers or parents wishing to help their child develop good writing habits for life. So, grab a pencil and follow along - you will be writing up a storm in no...

In this video the teacher shows us how to use a TI-84 plus graphing calculator to graph a function, adjust the view window, and determine the values of several types of critical points on the graph such as x-intercept, y-intercept, local maximums, and local minimums. After entering the function in the Y= editor she presses the ZOOM button and selects Z-Standard this adjusts the view window to a range of -10 to 10 on both axis. To find each of the critical points requested the teacher uses the...

The idea of finding the area under a curve is an important fundamental concept in calculus. Consider a function y = f(x). Now the area under the curve is to be calculated. The area under a curve problem is stated as 'Let f(x) be non negative on [a, b]. Find the area of the region lying beneath the curve y = f(x) and above the x-axes, from x = a to x = b. Note that finding the area under a curve will imply that you are dealing with a non negative function. The way to approach is to divide the...

Shelley Lovett from Childcareland demonstrates sand writing as an early childhood learning activity. All you need for this activity is a baking sheet that is approx one inch deep and some sand. Colored sand makes it more fun for the kids. Shelley says the cheapest place she has found colored sand is at Wal-Mart, but it is also available at craft stores and perhaps even at Home Depot or Lowes. You spread a thin layer of the sand onto the baking sheet and try to make it pretty even. For very...

In this video the math teacher explains the meaning of the indefinite integral formula in calculus by stating it in terms of antiderivatives. He then shows in general terms how this indefinite integral formula has a related derivative formula, i.e. if the derivative of F(x) is f(x) then the indefinite integral of f(x) is F(x) plus a constant term (C). With this general relationship the teacher takes us through three related examples where he converts a derivative formula to an integral formula....

This video demonstrates how to do anti-differentiate functions with radicals in calculus. To simply problems, try to substitute. For example, in the problem, the integral of x times the square root of x plus 2 dx. You can substitute w for everything underneath the radical: i.e. x + 2. When you simplify, it becomes: the integral of x times the square root of w dw. Now, you need to get rid of the x, which you can do with a substitution: w – 2 = x. Now, plug in the values and simplify it. The...

This video gives you brief tutorial on simplifying expressions, or canceling out common factors. He starts out by answering the question "What is canceling?" and demonstrates a basic example. You find the greatest common factor between the numerator and denominator, which you then divide both by. This can also be done if you have variables in your fraction. He then shows it can be done the same way if you have binomials in your fractions. However, you must be careful that the denominator does...
