Osmosis Investigation

Aim: To find out the effect of altering the concentration of sugar solution on osmosis in potato chips.

Introduction

Osmosis is an integral part of the OCR 21st Century Science course and comes up in Module B4 Homeostasis. This unit of work was the inspiration behind my choice of coursework. This area provides me with the opportunity to see science in action. The investigation chosen is one that can be safely carried out and the results can be readily observed and recorded without expensive lab equipment.

Osmosis is the diffusion of water across a partially permeable membrane from a region of high water concentration to a region of lower water concentration. This process takes place until equilibrium is established. Osmosis is a passive process. This means it happens naturally as all particles have some kinetic energy.

Factors that affect Osmosis

There are many factors that affect osmosis which are listed below:

* Temperature

* Surface Area

* Concentration

* The amount of water on each side of the membrane

The factor that I am looking at in my experiment is the concentration of the sugar solution in
