Science Fair Project Idea
Chlorophyll is a natural pigment found in green plants. It is the primary pigment that absorbs light energy from the sun for photosynthesis. This energy is then used by the plant to synthesize glucose from carbon dioxide and water. Chlorophyll in the leaves of plants can be extracted and separated using chromatography. A good source of chlorophyll for an extraction is a dark green leafy vegetable like spinach. Rub a fresh spinach leaf on the bottom of a strip of filter paper. You can get a… Read more

thumbnail Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different types of chromatography: paper, thin-layer, high-performance thin-layer, gas, and more. You will be using paper or thin-layer chromatography to analyze the compounds from different plants. Chromatography is used by analytical chemists, organic chemists, and many… Read more

thumbnail Have you ever looked at sunlight through a prism? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more

thumbnail This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other. Different materials can be attracted or repelled depending upon their molecular structure. We can utilize the different attractive forces between substances to separate a mixture of compounds. Chromatography is a method to separate mixtures and identify each compound in… Read more

Science Fair Project Idea
When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as swamp coolers. Evaporative cooling is also a potential source of energy waste in the kitchen because it increases the time it takes to heat water. In this chemistry science fair project, you will study how a variety of things cool down, whether for better or… Read more
