simplest  chromatography Smarties are colored using different dyes, which can be separated by chromatography. Find out which colors are made up of the most dyes and then eat the smarties! Ingredients Tube of Smarties Blotting or filter paper Recipe Place a smartie in the center of a circle of blotting paper Slowly drip water onto the smartie until a 5 cm wet patch surrounds it Leave until all the components of the dye have separated Eat the now white and soggy smartie Why does this work? In lots of cases, a dye is made up of several different colors all…

Find the DNA in a Banana Introduction What do you have in common with a banana? Even though we might not look alike, all living things—bananas and people included—are made up of the same basic material. Just like houses are made up of smaller units such as bricks, all living things are made up trillions of microscopic building blocks called cells. Within an organism, each cell contains a complete set of "blueprints". These directions determine the organism's characteristics. Background If we could zoom in on a single, tiny cell, we could see an even teenier "container" inside called a nucleus.…

How To Make Pulse Counter The rhythmical dilation of arteries produced when blood is pumped outward by regular contractions of the heart, especially as palpated at the wrist or in the neck.   The pulse is usually felt just inside the wrist below the thumb by placing two or three fingers lightly upon the radial artery. The examiner's thumb is never used to take a pulse because its own pulse is likely to be confused with that of the patient. Pressure should be light; if the artery is presse d too hard, the pulse will disappear entirely. The number of…
