A science project is a time to improve children's minds and enlighten them to all the possibilities that science has enabled. There are several different projects that would make suitable learning experiences for children. One of the most popular types of projects is a volcano made out of vinegar, baking soda and a container. The baking soda is a base while the vinegar is an acid; when they make
. contact they break apart into a foamy mixture of water and carbon dioxide, fizzing as it forms and emits carbonic acid. Another popular experiment is to make eggs float. It is an established fact that an egg sinks to the bottom because the egg is denser than the water. However, salt water is denser than tap water, thus an object that is less dense than it will easily float to the top. This simple experiment involves an egg, a glass of water and table salt. Start by adding about six tablespoons of salt to the glass of water, then add more plain water without mixing the two. Finally, gently lower the egg to see what happens. If the directions are followed correctly, the egg will float in the middle of the glass. Another more recent discovery is the reaction caused by mixing Diet Coke and Mentos candies. To do this, take a large plastic bottle of Diet Coke, half a pack of Mentos candies and a geyser tube. Go outside where it is possible to place protective plastic on the ground, stand the Diet Coke bottle upright in the center of the plastic and unscrew the lid. Then, put the geyser inside, drop the Mentos through the geyser into the Diet Coke and watch what happens. No one agrees on exactly why these two foods cause such a reaction, but one theory suggests that the carbon dioxide in the Diet Coke caused by small flavor particles on the Mentos cause the reaction. There are others, but these are the most enjoyable and innovative for young children. For more information, please see: http://www.reference.com/motif/Education/cool+science+experiments
