When you come back to the dish, you will see all the bacteria that has grown! This is a great science experiment to do for children in schoo...
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...
In this video tutorial, viewers learn how to do a sodium and water experiment. Sodium is a silver metal that is very reactive. When exposed oxygen in the air, an outer coding of sodium oxide will form. Simply drop a piece of sodium into a cup of water. When dropped in water, sodium reacts to form sodium hydroxide and hydrogen gas. The sodium will constant move around in the water. Sometimes the heated reaction will cause the nitrogen gas to ignite. Under the right condition, it may even cause...
