22 Hydrogels EOH 2009 This exhibit is suitable for: All Location: First Floor This exhibit is suitable for: All Undergraduate Materials Organization Learn how hydrogels work and why they can be used in many applications. There will be samples of hydrogels to touch, as well as demonstrations of how hydrogels in items like diapers can swell to many times their size. See what happens to hair gel when people “sweat”. Other examples of hydrogels will also be provided to show the diversity in their functions. Location: First Floor This exhibit is suitable for: All Materials Challenge Location: First Floor This exhibit is suitable for: All Undergraduate Materials Organization Here, there is a hands-on project where you build plaster beams with different reinforcements. Have some fun trying to build the strongest cement block! Compete with friends and family! Location: First Floor This exhibit is suitable for: All Piezoelectrics Undergraduate Materials Organization An exploration of common piezoeletrics, such as those used in watches and various modern applications. Location: 100 This exhibit is suitable for: All Materials Science of Food Undergraduate Materials Organization and Candy Undergraduate Materials Organization The general idea of our project is to illustrate through demonstrations and posters the material science of different food items, such as caramel and Jell-O. Location: 100 This exhibit is suitable for: All Recycling Aluminum Hydrophobic and Hydrophilic Materials Undergraduate Materials Organization A demonstration of hydrophobic and hydrophilic materials. There will be demos of “magic sand” that visitors can mold under water, but it is dry when you pull it out. There will also be some small demos with oils and water, as well as informational displays. Location: First Floor This exhibit is suitable for: All Mechanical Properties of Materials We will be comparing recycling aluminum with manufacturing aluminum. The costs of recycling aluminum will be analyzed and compared to the costs of manufacturing aluminum. We will have an interactive game to help explain the process of recycling aluminum. Location: First Floor This exhibit is suitable for: All Liquid Crystals and Optical Materials Undergraduate Materials Organization Visitors will be able to use a small, levered machine in order to attempt to deform polymers, ceramics, and metals in three tests. Location: First Floor This exhibit is suitable for: All Stored Energy Solar Cooker Undergraduate Materials Organization Come see examples and demonstrations of different liquid crystals and optical materials, and learn about their importance to material scientists. Location: 100 Non-Newtonian Fluids Undergraduate Materials Organization We’ll discuss non-Newtonian fluids, which include dilatants, pseudoplastics, and ferrofluids. Our exhibit includes hands-on and visual demonstrations. Engineers Without Borders We are presenting a scale working model of our design of a stored energy solar cooker. Heat is collected and stored during the day, and make it available later for use in cooking. Come learn about the benefits of solarpowered cooking! Our goal is to complete construction of a full scale version later this semester. Location: First Floor This exhibit is suitable for: Middle School, High School, College, General Public
