Extract

For this investigation we are going to find out whether potato chips placed in a range of different concentrated sugar solutions increase or decrease in mass.
Background knowledge
Osmosis is the passage of water molecules from a weaker, dilute, solution into a stronger, more concentrated, solution through a semi permeable membrane.
Each cell in a leaf is surrounded by a membrane, which separates the contents of the cell from the outside. The membrane has tiny holes in it, which allows small molecules only to pass through it.
