Investigating osmosis in a vegetable

Posted: September 8, 2014

In Year 10 Science, students are investigating osmosis, the diffusion of water. Water naturally diffuses from areas of high water concentration to areas of low water concentration. Students measure the initial mass of a vegetable piece, soak it in a solution overnight, and then weigh the final mass of the vegetable after it has soaked. The change in mass of the vegetable determines whether water diffused in, or out, of the vegetable.
