Tap water Method Peeling down the potato and cutting it into 1cm3 cubes (25 cubes) Weighing potatoes on the scales Putting different amount of sugar into five plastic cups (1st no sugar 2nd 6,8g 3rd 13,7g 4th 20,5 5th 27,4g) Adding 100ml of water to each of the cups Mixing the sugar with waterPutting in 5 potatoes into each cup Waiting 20 minutes Pulling out the potatoes, drying them up and putting on the scales Writing down new mass.

Conclusion The potato lost more mass as it was submerged in bigger concentration solutions because the bigger concentration difference is, the osmosis will occurs more intensively. Evaluation I think that laboratory work went pretty well, I managed to see the differences in potato mass change and make a conclusion of it. Next time I should write down original numbers and not rounded ones to give more accurate results.
