In this video, we learn how to understand organic molecules in Chemistry. First, you will need to take a look at the chemicals that are inside of each of the different molecules. See how the molecules are made out and then see what number of different acids are inside of them. Once you learn this, you can see what the difference between this and other molecules are. This can all help you understand the beginning and end of what's inside of the molecules. If you aren't good at chemistry, you w...
Mike Lively of Northern Kentucky University shows you how to build an interactive Molecule Viewer in Papervision3D and Flex 3. This is a fun application building project for anyone learning Adobe Flex Builder 3 and a great resource for molecule viewer for students, educators, and researchers in chemistry and biochemistry.
Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined fr...
This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...

In this video tutorial the instructor demonstrates resonant frequency. In this video the instructor shows the sound of resonance and how to generate it. Resonance is a forced vibration of energy into molecules of an object that makes those molecules vibrate at their resonant frequency. When these molecules vibrate naturally they produce a kind of noise that can be annoying some times. In this video the author makes a small object using a rubber band and a net that produces vibrations when rot...
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...
This video provides instruction on how to make "buckyballs" (dodecahedron, truncated icosahedron) from "PHiZZ" units. It looks complicated but it is really easy to make.
Cooking instructions at John's Cuisines, the all-time Filipino favorite dishes are now unveiled to the whole world.
Do you understand organic molecules or oxidization in chemistry? If you answered no then this is the video you need to watch. This video will show you grade 12 chemistry, with organic models, and will teach you about oxidization. In less than 4 minutes you will have a much better understanding of the topic. This is demonstrated with a few common chemicals which include potassium dichromate and ascorbic acid. Ascorbic acid or vitamin C is found in many foods that we eat including fruits and ve...

Instruction on how to make a spiked truncated icosahedron AKA "Hairy Buckyball" (don't think it's an official stellation of the truncated icosahedron) or Buckminster fullerene molecule (every spike is a C-atom).
It's a small but very real frustration: you want a chilled drink, but you open the freezer only to see nothing but empty ice trays. Fortunately, there's a simple way to make ice cubes quickly—use hot water. Yup, you read that correctly. Hot water freezes more rapidly than cold.
In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...
If the all the fingerlike projections in our gut were flattened out, its surface area would be 100 times bigger than our skin's. It's so large that the actions of just a small part of it can impact our health. A new research study has found that enterochromaffin cells in the intestinal lining alert the nervous system to signs of trouble in the gut — trouble that ranges from bacterial products to inflammatory food molecules.
Smelly foods are what make my culinary world "go 'round," so to speak. I grew up with fish sauce, learned to cook with and love fermented beans and veggies, and am one of the biggest garlic advocates I know... other than my husband, who thankfully shares the same smelly food sensibilities. (Let's put it this way: anyone that can stomach stinky tofu can handle anything I could possibly cook up.)
In this video we learn how to make a candy DNA model. First, purchase some black licorice and another color. Grab two each from the pack and then purchase some gummy bears. After this, pick out four different colors from the gummy bears bag. Take your scissors and put the licorice together. Cut one inch pieces so you end up with six of them. These will represent the sugars in the molecules. Once you do this, you will take the string and push it through the holes that are in the licorice. Laye...
Here's a fun experiment you can do that will demonstrate the effects that pressure has on the freezing point of a liquid. You will amaze your friends as you do what seems to be impossible, turning water into ice without sticking it in the freezer.
Lance Lund, a professor at Anoka-Ramsey Community College, was asked to prepare a promotional science video for the college back in 1995 that was to air on a local cable access channel. All went well until he inhaled some sulfur hexafluoride (SF6). The video never aired, but many more of you from around the world will be able to enjoy this right here.
If you plan on being a physiologist, or you just like science in general, then go no further than these five video tutorials on the cell transport physiology of the human body.
Having someone send you flowers will almost always lift your spirits. Wilting, dying flowers, on the other hand, aren't so great to look at and smell even worse. While there are time-honored tricks to keep flowers alive longer (change the water regularly, put a penny in the bottom of the vase, and cut stems diagonally are three that come to mind), it turns out that a few items in your kitchen are pretty useful at making sure those blooms stay perky.
Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
Maybe not water per-se, but with this simple technique you can turn one of the most abundant materials on earth into a highly explosive gas.
