AIM: Movement of water into and divulge of the potato.
Apparatus: Cork Borer, Potato, Test Tubes x2, sucrose Solution, Rack
Method:
1. We stack away Test supplys and labled them A & B.
2. We half filled the the scrutiny tubes with 0.1M of Sucrose solution and 1M Sucrose solution
3. Collected a potato and apply a cork borer to cut out 2 cylinders from the potato.
4. The cylinders were trimmed to equal length.
5. The cylinders were dried to remove the liquid from the outermost surface.
6. They were gently squeezed to feel it was soft or firm.
7. We used an electronic balance & weighed both cylinders and took a note of its initial mass.
8. consequently we immersed the cylinders into the test tubes A & B
9. After 40 minuets we took flock the results.
Results
----------------------- 0.1M 1M
Initial Weight - 4.0g 4.0g
Final Weight 5.13g 3.86g
0.1M: +3.25%
1M: -3.5%
Class Results:
give ear 0.1M 1.0M
E+B +7.3% -7.3%
M+S +2.13% -4.35%
K+C +4.3% -8.
5%
M-L+S +8.6% -2.6%
F+M -23.8% -2.7%
S+A +47.6% -19.4%
S+S +2.95% -8.33%
C+S +3.25% -3.5%
H+E +2.5% -2.6%
J+M +5.9% -5.9%
Conclusion:
In the 0.1M sucrose test tube showed that my result was +3.25% and that the class average was +6.07%
In the 1M sucrose test tube showed that my result was -3.5% and the class average was -8.97%
Evaluation
If the potatoes were not rolled on paper towel each time whence the results would be invalid because then the potato cylinder wouldve had more mass before we started the experiment. To make this experiment more undeviating then we induct a class average.If you want to get a full essay, order it on our website: Orderessay
