How To: Make your own thin-layer chromatography (TLC) plates
The price of TLC plates can add up. See how to make thin-layer chromatography plates (TLC plates) for a few cents each that are as good as commercial TLC plates that sell for a dollar or two each. You can use these home-made TLC plates the same way you'd use chromatography paper, but the plates provide sharper separations and require far less analyte. They also lie flat, and are much easier to store for later reference. For more information, including step-by-step instructions, and to get sta...
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.

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: Measure the volume of a balloon
Here we will demonstrate how to measure the volume of a balloon. A balloon is not a straight edged polygon shape, usually, so the mathematical equations get that much harder, on the flip side, it may be a spherical or ovalish shape, but measurements with math alone are detrimental due to the uneven sizes of the balloon. Here is how to do it properly. You will need a bucket, preferably, to hold water, a larger container than your original bucket, and a measuring container. Place the bucket ins...
How To: Experiment the law of inertia
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...
How To: Draw the Lewis structure for carbon dioxide & methanol
In this Education video tutorial you are going to learn how to draw the Lewis structure for carbon dioxide & methanol. Carbon dioxide is CO2. Oxygen atoms don’t bond together. So, carbon atom has to be in the center. Oxygen has 6 valence electrons and carbon has 4. Hence, carbon wants to form 4 bonds and each oxygen atom wants to form 2 bonds. So, two each electrons of carbon will bond with 2 electrons of each oxygen atom. The Lewis structure for CO2 will be ( …. O=C=O….). The 4 dots within t...
