Egg Flotation

Egg flotation Objective/Question/Problem My objective is to see which screwball will float. The question is how much salinityiness is needed to be added to make the egg float. The problem is that I do not know how much saltiness is needed to make an egg float. Hypothesis If I add salt to the water then the egg will float because the egg has a parsimony that is lower that the parsimony of the fluid it displaces. Background Information If the object has a density that is higher than the density of the fluid it displaces, it will sink.If the object has a density that is lower than the density of the fluid it displaces, it will float. virtually objects that sink in fresh water will float in salt water. This is because saltwater has a higher density than freshwater. Websites that I used for this project are the ones below. www. ehow. com Education www. sciencehound. com/science_project_community/node/7206 www. blurtit. com/q729307. html answers. askkids. com How tug Works ww w. thegeminigeek. com/why-an-egg-floats-in-salty-water/ VariablesThe manipulated unsettled is that the water will be changed one is salt water and the other is not. The Responding variable is that I will measure how much salt is needed to make the egg float. The controlled variable is that I will be the one doing everything and recording the project, and I will have the same type of eggs. Materials 2 eggs tab water Two Beakers salt stirring stick Measuring cups Experimental Procedures footprint 1 Put the water in cup half port upStep 2 Put 6 tsp of salt into the water. Step 3 Mix the water and salt with stirring stick until you cant see the salt at the bottom. Step 4 Gently Put in the egg and record what happens. Data analytic thinking As you can see in the first tbsp the egg floated about 200mL. later putting the warrant tbsp it floated up to 350mL. The third and fourth tbsp stayed the same at 500mL. After putting in the fifth tbsp it raised(a) up to 600mL. The las t tbsp did not make the egg rise all the instruction to 800mL it only raised up to 750mL. DataMy observations are that eggs could float because as the density of the water increased then the heavier objects could float. After each tablespoon the egg would rise little by little to get all the way to the top. After I put the egg in with all 6 tablespoon in the beaker I put the egg in and it sinked all the way to the bottom. After 1 minute passed it floated all the way up. Conclusion Eggs could float because the density of the water increased which it made the egg float. The more salt you put the more the egg will float.
