How To: Do a yeast experiment to see how much C02 it produces

In this Education video tutorial you will learn how to do a yeast experiment to see how much C02 it produces with different types of food. Yeast is a fungus and it has to eat. After it eats, it produces CO2 gas. The bubbles in bread are produced by the CO2 gas from the yeast. Take five different types of food items and measure out the same quantity for each item. In the video it is 8gms of cookie, oil, flour, salt and sugar. Take six glasses of water and mix one packet of yeast in each glass....

How To: Divide exponents with the quotient rule

Exponent of a number is nothing but the number multiplied to it self the exponent number of times. So five squared it equal to five multiplied to it self. Now when an exponential number is divided with another such number the result is the number raised to the different of the exponents. That is the ratio of x raised by a to x raised by b is x raised to (a-b). Similarly if we multiply a exponential number with other such number, the result is equal to that number raised to the sum of exponent...

How To: Wear your pashmina shawl or wrap three different ways

The Pashmina master shows us three unique ways to wear our pashmina shawls. The first one involves putting your pashmina on your left shoulder and gently slide it over your chest till you reach your other arm. Then you easily raise it until you cover your other shoulder too. Don't forget to leave the other end hanging up front as it's part of the process. The second example needs the pashmina to go over your neck like a scarf. Then you take both ends and run them through the pashmina just lik...

How To: Simplify expressions involving numeric radicals

In this video tutorial, viewers learn how to simplify expressions involving numeric radicals. This can be very frustrating to work with if you have not memorized the tables of square, cubes and fourths. If you are taking the square root of a number that is not a perfect square and you wish to simplify it, the key is to write it as the product of a perfect square or another number. This video is very descriptive and clearly explains the functions of the formula. This video will benefit those v...

How To: Simplify expressions involving algebraic radicals

In this video tutorial, viewers learn how to simplify expressions involving algebraic ratios. In some ways, simplifying algebraic radicals is easier than numeric radicals. When we are working with square roots, we need to find the highest even power of a variable to act as out perfect square. When working with cube roots, we look for the highest multiple of 3 as an exponent for our perfect square. This video is very descriptive and clearly explains all the functions of the formula. This video...

How To: Complete a proof involving segments

This video from Yay Math! is a geometry lesson on how to complete a proof involving segments. He draws a line segment with four points labeled A, B, C and D. The problem is as follows: Given: AC is equivalent to BD. Prove that AB is equivalent to CD. The first statement of proof is the given. Next, you need to define the congruent segments and state that they're equal in measurement. Next, break down the segments: AC=AB+BC, and BD=BC+CD. This is called segment addition postulate. The end of t...

How To: Square expressions involving radicals

Here we look at squaring expressions that involve radicals because people tend to make some common mistakes while solving such expressions. Take 5 times the square root of y quantity squared, the answer here is not 5y. Here's the reason, square means to multiply something with itself so the square of 5 root y would be 5 root y into 5 root y. So 5 x 5 is 25 and under root y into under root y equals just y so the answer will be 25y.

How To: Solve equations & inequalities with absolute value

In this tutorial the instructor talks about various strategies for solving equations and inequalities involving absolute value. To do this the first step is to isolate an absolute value. An absolute value is exactly equal to a number. If that number is less than zero then there is no solution. So, if you have an absolute value that is less than a number it means that the real value lies in between negative and positive value of that number. If your number is less than zero then it is empty se...

How To: Do long division with different approaches

Taking equal groups, in our case, 7 out of the whole number, in this case 364 involves guessing. A shorter method involves taking groups, in our case, 7 out of each individual number 3, 6 and 4. If you cannot take 7 out of a number, you will subtract 0 from that number and carry down the next number. For example, you cannot take 7 from 3, so you will subtract 3-0 with the answer being 3 and carry down the next number, 6, giving you 36. You can take 5 groups of 7 out. 5 groups of 7 equals 35, ...

How To: Make fire without matches using acetone and magnesium

In this how-to video, you will learn how to make fire without using any matches. You will need Manganese heptoxide and acetone to do this experiment. You will also need a rod, pipette, and glass beaker. Please exercise caution before doing this experiment, as it involves fire. Place the Manganese heptoxide in the glass beaker. Using a pipette, place a few drops of acetone around it. Now, place a drop on top. Be careful, as the Manganese heptoxide will ignite as soon as the drop hits the mater...

How To: Control a slice in golf

This video presentation details how to control and reduce a slice in golf. Materials required include a golf club, golf balls, and optionally a tee. Ideally a wood would be involved in this practice. How to control the slice is somewhat of a misnomer since the intent of the process is to remove the slice since it can be an unwanted thing. A slice is when a golf club is swung and the club remains 'open', this is when it is facing toward the right as the swing is coming through, this imparts a ...

How To: Understand arithmetic basics to do long division

This video shows us how to understand the basic arithmetic for doing long division. Whenever you are about to perform the division operation, the number which is to be divided is called as the dividend and the number which divides the dividend is called as divisor. So while performing a very long division, usually the dividend is put under a bar and the divisor is put upfront. So while dividing the dividend, the divisor is made to check whether it can divide the numbers involved in the divide...

News: Experiments in Stock Market 3D Data Visualization on the HoloLens

HoloLens developer Michael Peters of In-Vizible has released quite a few videos since receiving his HoloLens last year.

Classic Chemistry: Colorize Colorless Liquids with "Black" Magic, AKA the Iodine Clock Reaction

Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

News: Brain Hacking and Thought-Controlled Quadcopters: The Good and Bad Future of Mind-Reading Devices

Until recently, brainwave-reading devices have pretty much only existed in science fiction. Sure, electroencephalography (EEG), the technology that powers these devices, has been used in medicine and psychiatry since the late 1800s, but diagnosing people's brains and reading their minds are two totally different things. The first EEG headsets available to the public were used mostly in gaming and even in fashion, but in the last few years, they've gotten a little more sophisticated.

How To: Use the Eraser, Scissors and Knife tools in Adobe Illustrator

How To: Make a tea bag rocket and blast off

3,2,1... blast off! Here's a fun little experiment you can do with a tea bag and some matches. You can try it at home and see how far up you can make your tea bag rocket go. The Tea Bag Rocket is really an adaptation of a classic science demonstration called the Ditto Paper Rocket. Each piece of Ditto paper had a sheet of tissue paper that separated the two-part form, and it was this discarded piece of paper that kids used to make the "rocket." Since Ditto paper is a thing of the past, scienc...
