is to see if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water. Background

Will the egg float or sink if put in salt water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The

How to float an egg in the middle of water? Objective: To understand how density works and how you can change the density of a liquid. Materials Needed: Procedure: 1) Fill 3 glasses with 250ml of water and place a fresh egg in one of the glasses‚ watch as it sinks. 2) Put 4 tsp. of salt into one of the glasses stir it up and place an egg in the water. Watch as it floats. 3) Put 4 tsp. of salt into the final glass stir it up and pour out some of the salt water. Now place an egg

How Much Water Does Epsom salts Contain? Purpose The purpose of the experiment was to find the percent of water in Epsom salts by heating it. To find the percent of water in a hydrate‚ the hydrate must be heated. The experiment did not only show how dehydration occurs‚ but this experiment also gives an accurate and definite portrayal of the amount of water that is removed Background Information A hydrate is any compound that contains water. An anhydrous compound is a hydrate in which the water

Does Thinking Take Too Much Time? In discussions of human thinking‚ a controversial issue has been whether thinking takes too much time and we as humans would rather go with what we are told to do or what others around us are doing. On the one hand‚ some argue that thinking takes too much time. From this perspective‚ people are becoming lazy and do not want to think for themselves‚ so it is easier to just agree with what others have said. On the other hand‚ however‚ others argue that humans do

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min

falls‚ making you liable for injuries. So most people rely on deicers such as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete.

The song ”Float On” by Modest Mouse has changed how I feel about my surroundings. It made me realize that I am just one small part in a bigger world. The piece begins with the line‚ “I backed my car into a cop car the other day. Well he just drove off sometimes life’s okay”. This line uses the listener’s previous knowledge of how cops react to accidents to show how sometimes people can surprise you. When people do the unexpected they can change your life for the better. It’s actually my favorite

The Effect of Osmosis on The Mass of Eggs Victoria Vu Biology October 22‚ 2013 Introduction & Hypothesis The membrane of an egg is composed of keratin (a type of protein)‚ which is semipermeable. This means only certain materials will be allowed to enter and exit through the egg’s membrane. The purpose of this experiment is study the process in which water molecules pass the egg membrane‚ osmosis. This experiment also gives insight on how other ‘semipermeable membranes’ work‚ like a
