i thought so the same .. wood is also a non conductor .. but how would u get a block of the same size.. ?? :P

use thick rigid wire toconnect electrodes. remove electrodes from beaker vertically. measure.
this is what i would write at least..

wont the resistance decrease .. ??

Supposing the gap needs to be 1 cm large.


Cut a wood block of 1 cm length. Then place the block into the beaker and shove it in between the electrodes.


DONE !

if you use it from the start of the experiment it wont matter, they are only investigating condution of current through the solution
