Osmosis In Potato Cells

Ben Zaré 9MK Biology Investigation - Osmosis in Potato Cells 9/7/04

Section 1 – Planning

Aim
What is the aim of your experiment? What do you want to find out?
The aim of this experiment is to investigate how potato tissue changes when placed in sucrose solution of different concentrations. Therefore, I want to find out if and how osmosis differs, when the concentration is changed.

Variables
What is the variable you are going to change in the experiment?
The input variable of this experiment (i.e. the variable to change) will be the concentration of sucrose solution present in the test tubes, which the potato samples will be placed into.

What is the variable you are going to measure in your experiment?
The output variable of this experiment (i.e. the variable to measure) will be the mass and length of the potato sample, before and after osmosis has occurred.

What are the other variables in your experiment? How can you keep them......
