These demonstrations, created by agriscience education students in the teaching methods course, are designed to engage students in agricultural and environmental sciences.Each day from 9am-3pm, agriscience education students will also lead wagon tours of the Gwynne Conservation Area, which includes a butterfly garden, natural streams, wetlands, ponds, windbreak plantings, wildlife food plots, a soil pit, and more.Demonstration topics are:Wednesday: Soy InkTo make soy ink, soybean oil is slightly refined and the blended with pigment, resins and waxes. Soybean oil is naturally clearer than petroleum oils, making it easier to obtain brightly colored ink. Since the oil is clearer, less pigment is necessary to produce the same effect. In addition to a brighter ink, printers report that they need less ink to print the same out of paper when compared to petroleum inks. In this activity students will create and test two paints and soy inks. Thursday: Engineering Egg Catchers It takes 30 million eggs a day to satisfy the U.S. consumer! Ohio is No. 2 in the nation in egg production and ag engineers have helped to design facilities that keep chickens safe from predators and disease, comfortable in all kinds of weather and allow the animals easy access to water and food made from soybean meal. In addition, the eggs the animals produce must be safely transported, cleaned and packaged. In this activity students will use the engineering design process to imagine, plan and test a prototype egg catcher.
