experiment. In this experiment‚ strips are cut from the same potato and placed in sucrose solutions with different concentrations to see if there are any changes in term of weight.

purpose of the lab was to discover‚ through osmosis‚ the concentration of sugar water in a potato. First‚ potatoes were cut into strips about 3 centimetres in length and six strips were individually massed. Next‚ the six strips were placed in 6 different Dixie cups‚ labelled A‚ B‚ Q‚ X‚ Y‚ and Z. Each of the Dixie cups were then filled just enough to cover the potato strips‚ with substances that matched the letters of the cups.
