Hypothesis : my supposal is that the white white potato will shrink in size because when you repose the potato in the scared upshots the water likely immaterial the potato will be less than the water potential inside the potato therefore , the potato will shrink.
Variables :
1.Independent : concentration of the solution
2.Dependent :mass of the potato
3. Controlled variable:
Temperature
The amount of the solution
Materials :
1.4 beakers ( atomic number 6ml)
2. potato
3.knife
4.cork ( size 2)
5.ruler
6. Graduated cylinder (25 ml )5
7.balance
8.weight boat
9.dropper
10.forceps
11.solutions with different concentration :
50 ml of 0.1 of kale concentrated solution
50 ml of 0.2 of chou concentrated solution
50 ml of 0.3 of plunder concentrated solution
50 ml of 0.4 of sugar concentrated solution
50 ml of 0.5 of sugar concentrated solution
50 ml of distillated water.
influence: as the paper attached.
Table: the mass of the potato earlier and subsequently its placed in the solution.

1 of sugar concentrated solution0.44 kg0.43 kg
20.2 of sugar concentrated solution0.48 kg0.42 kg
30.3 of sugar concentrated solution0.49 kg 0.44 kg
40.4 of sugar concentrated solution0.50 kg 0.44 kg
50.5 of sugar concentrated solution0.44 kg 0.44 kg
6distillated water0.41 kg 0.43 kg
Graph: in the attached paper.
info processing:
1. portion counterchange in mass :( final mass initial mass/ initial mass)*100.
Percent change in mass for potato 1 =0.43-0.44/0.44*100=-2 %
Percent change in mass for potato 2 =0.42-0.48/0.48*100=-12 %
Percent change in mass for potato 3=0.44-0.49/0.49*100=-10%
Percent change in mass for potato 4=0.44-0.50/0.50*100=-12%
