Science Fair Slideshow: Osmosis and Diffusion

  1. 1. The Beginning It all started in Learner High School‟s Biology class,where I learned a lot about cellular processes likeosmosis and diffusion. That‟s when I decided to try tore-create those processes using eggs as the animal“cell”.
  2. 2. The Project I spent the next four weeks working on the project. First, I submersed the eggs in different solvents to make them more permeable.Salt-water solvent Sugar-water solvent Water solution
  3. 3. The Final TestAfter 48 hours, I dried each egg and carefully poured certainamounts of each solvent over each egg. Then, I measured how much ofeach solvent actually passed through the egg. After that, I determinedwhether the egg was penetrated through osmosis or diffusion.Exhibit A (Salt-water egg) Exhibit B (Sugar-water egg) Exhibit C (Water egg) 15 ml 7ml 0 ml
  4. 4. Data After many tests, I finally found out that eggs A and B were penetrated through osmosis and that the project was a success.
