We investigated this using some cubes cut from agar gel that had an indicator added to it. By placing the agar blocks into Sodium Hydroxide solution the bright pink colour of the agar blocks showed us how far the Sodium Hydroxide had diffused.

Surface area to volume ratio experiment
One reason that cells are small is: Small objects have a larger surface area compared to their volume than large objects. This means that the transport of materials into and out of cells can occur easily through simple diffusion rather than requiring the more energy costly active transport.

How long did you have the agar in the sodium hydroxide?
