Title: Creating the chemical reaction of Osmosis with an Egg.
Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration.
Introduction: When trying to create an osmosis reaction, it is important to understand Hypotonic and Hypertonic solutions. When a cell is placed in a hypotonic solution water diffuses from its surroundings and will enter the cell and cause it to swell. Both plant and animal cells when placed in a hypertonic solution, water will leave the cell and the shell will shrink because the water moves from the cells which have the higher water concentration to the surroundings. Diffusion is a passive process where the cell has no control over the rate or direction of diffusion. The direction of diffusion is determined by the relative concentration of specific molecules on each side of the membrane. The energy supplied for osmosis to occur comes from the kinetic energy of the molecules themselves.
Hypothesis: I believe the egg will lose mass while submerged in the Karo Syrup because it doesn’t contain much water and when the egg is placed in water, I believe it will gain mass showing the process of Osmosis – where water will move through a semi-permeable membrane.
Materials & Method: Material used: 3 Eggs (1 used – 2 for backup) Vinegar Karo syrup (light) Water 3 containers to hold eggs Scale Towel Sink
I placed 3 eggs in a container and filled Vinegar and let sit for 24 hours. After 24 hours had passed, I
