Essay --

Food related projects are super interesting, projects that have to do with seeing changes when you add disparate nubs and how it affects the outcome. Last year, I did a project on how acids affect the rate of corrosion of steel wool. This year, my focus was food, especi each(prenominal)y cook. My research resulted in projects involving different amounts of baking soda and their affect on cake texture, or how chips lose their crunch. Then, an idea stood out to me what bewilders colloidal gel and gels so strong. I wondered, what is in gels that make it strong and piano to form a shape. That led me to forming my question What sorts of substances make gelatin the strongest?HypothesisIf different substances are added to gelatin, then it is expected that the citric acid would make the gelatin strongest because it is found in gelatin tr tuckers like sour gummy worms, which have a strong texture. GoalsFind a substance which makes the gel strongest. See what substance weakens the gel.Fi nd out what can make a gel go from strong and firm to a jelly-like consistency. Determine if the pH has anything to do with the gel organism strong. See whether or the not the substance being a solid or liquid affects how strong the gel reachs. Find what substance can make the gel to shake. Background Information/Review of Literature The Egyptians first used gelatin, they found gelatin in the Pharaohs tomb in the form of glue. In 1682, Denis Papin, a Frenchman, took out tissue from animal bones and boiled it. He created a pure protein. In 1753, an Englishman made the first gelatin, and from then on, it got manufactured and became an industry. Gelatin is something that we eat a lot in our lives. Foods that contain gelatin are Jell-O, gummy bear... ...Use different substances like detergent, soap, egg whites, or cheese. Do the experiment chthonian the sun and see which is strongest.Use sweetened gelatin instead of unsweetened.Different Experiments-How does temperature affect gels t o become strong?How do bananas, apples, and grapes affect how strong gels will become?How do different amounts of gelatin affect how strong it becomes?Does pH affect how strong a gel is?AcknowledgementsI would like to thank Ms. Simmons who helped me step by step for the Science Fair. She guided me through all the work necessary to make a good project. She reviewed my Research Paper to make sure it met all of the criteria and check for any mistakes. I would like to thank my mom and dad who got me all the supplies and helped me make my project possible. When I needed help, they were always there to spark off me.
