State+Fair+Soil+Conservation+Booth

On Sunday, October 15th, 2017, I went to the fair to help Mrs. Shelia Jones teach people about soil conservation. Many people came of all ages and occupations. At our booth, we had multiple demos on soil. We had one on the multiple colors of soil, apparently soil is not just brown; it's also blue and green and even white. Also, I taught kids about the texture of the soil. Soil scientists have a competition where they must determine the amount of clay soil, silt soil, and sand soil that is within the mystery soil based on a triangular chart. Next, we had a demo on the deterioration of the mineral/chemical coating of soil, which is very similar to what happened to the Statue of Liberty. After that, I taught some children about soil filtration and how sand isn't a very good filter. Then, I learned something new with this particular demo which was on the electricity of soil. This demo went along with the filtration demo, because in the filtration demo i poured a green drink down a bottle of clay; but the liquid that came out of the bottom wasn't green, it was yellow. This happened because clay has a negative charge will the blue particles in the green solution have a positive charge, and the rule //"opposites// //attract"// was applied and the blue particles stayed within the clay soil. Finally, I learned how to do a pH test on soil. It's easy yet difficult at the same time. At the end, I talked to farmers, parents, and other adults about soil testing and how they can do it and turn it in to NCSU. This applies to APES because later on in the year we will be learning about soils and how they filtrate pollutants and other liquids within the environment.
