Effect of Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg

Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for

Diffusion and Osmosis Experiment with a Shell-Less Egg After Three days of Testing Methods with Water and Corn Syrup Lisa July 1‚ 2013 Purpose To use the properties of diffusion and osmosis to see the effects of either corn syrup or water on a shell-less raw egg over a three day period. While looking to see the effects of these liquids on the raw egg‚ one can also apply the properties of hypotonic‚ hypertonic‚ and isotonic solutions. Introduction Cells have an outer covering called the cell membrane

A. Stanford Prison Experiment- In this experiment‚ students volunteered to be a part of a psychology experiment that was being conducted at Stanford College. Because of the situation around them‚ they conformed to the environment‚ even though it was only a simple experiment in a Stanford hallway. Embarrassed and yet impressed‚ the experimenters stated this‚ “The negative‚ anti-social reactions observed were not the product of an environment created by combining a collection of deviant personalities

Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference

Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this

When you start you should have put the gummy bear in the water and the other in the plastic bag. The one in the water at the beginning of the experiment had a thickness of 9mm a width of 11mm and a height of 22mm and it had a total mass of 2.59grams and a total volume of around 2178 mm 3 The one in the plastic bag is going to be the constant It massed at 2.53 grams and had a height of 21mm a width of 12mm and thickness of 11mm and a total volume of 2772mm3 .
