Osmosis is the chemical process of diffusion, involving the transfer of solvent with a lower concentration of a certain solute through a semipermeable membrane, and into the area containing a higher concentration of that solute it sounds like a confusing concept to teach younger children just. In biology, the osmosis effect can be demonstrated in a number of ways in schools, there is a standard apparatus for demonstrating osmosis with visking tubing however, osmosis can also be demonstrated using household ingredients, as described below an egg contains a semipermeable membrane. Reverse osmosis was not practically demonstrated until the early 1960s with the invention of asymmetric membranes at university of california at los angeles. Class practical in this procedure, you can observe osmosis in an animal system by using chickens’ eggs from which the shells have been removed by dissolving in acid.
