Lab 2A:
Introduction
In this lab, you will be studying osmosis across the membrane of
potato cells. You will create equal-sized pieces of potato and then
place the pieces in solutions with differing concentrations. You
will then, over time, measure any changes that take place in the
size and weight of the potato pieces.
To measure changes in size, you will need either a gram scale
(like a food scale) or a millimetre ruler. It is best if you have...

Procedures Place two 150 mL Erlenmeyer flasks from the Containers shelf on the workbench. Double-click on the flasks to label one flask “A” and the other “B”. Obtain a 10 mL graduated cylinder and a 50 mL graduated cylinder from the Containers shelf. Place two constant temperature baths from the Instruments shelf onto the workbench. Set the temperature on each bath to 21.5 °C. The contents of each flask will vary with each trial as indicated in the table below....
