Potato Lab Sample Essay

Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isosmotic solution is a concentration and solution that is the same sum.

Hypothesis inquiry: What will go on if you put a murphy in hypertonic solution? What will go on if you put a murphy in hypotonic solution? What will go on if you put a murphy in isosmotic solution?

Hypothesis statement: If you put sugar H2O in one cup. salt H2O in another cup and field H2O in another cup so the piece of murphy will spread out in the sugar H2O psychiatrist in the seawater. and remain the same in the regular H2O because of the hypertonic. hypotonic and isosmotic solution.

Materials:
3 cups
Scale
Measuring cups
Water
Sugar
Salt
Paper pencil
3 murphy pieces







Procedure:
1 ) Gather stuffs
2 ) Cut the murphy into 3 small pieces
3 ) Weigh each piece of murphy on the graduated table
4 ) Record the weight of each murphy
5 ) Make a hypertonic solution. ( 20 milliliter of H2O. 80 gms of sugar )
6 ) Make a hypotonic solution. ( 80ml of H2O. 20 gms of salt. )
7 ) Make an isosmotic solution. ( 100 milliliter of water. )
8 ) Topographic point one murphy in each cup and record which murphy goes in each cup.
9 ) Leave overnight








10 ) Following twenty-four hours. take out each murphy piece one at a clip
11 ) Record the new weight of each murphy on the graduated table.
12 ) Put the murphy pieces in the same solutions they were in.
13 ) Repeat steps 9-12
14 ) Clean up experiment
15 ) Find the differences in weight of each murphy piece.
16 ) Write decision





Data and Analysis:
| Initial Mass| Day 1| Day 2| Change |
20 % Hypotonic Solution Salt| 8. 2 grams| 8. 0 grams| 7. 9 grams| -0. 29 grams| 80 % Hypertonic Solution Sugar| 8. 0 grams| 6. 5 grams| 5. 6 grams| -2. 4 grams| 100 % Isotonic SolutionWater| 8. 0 grams| 10. 0 grams| 10. 3 grams| 2. 3 grams|

Decision:
What will go on if you put a murphy in hypertonic solution? What will go on if you put a murphy in hypotonic solution? What will go on if you put a murphy in isosmotic solution? The murphy in the hypertonic will shrivel the most out of all the solutions. The murphy in the hypotonic solution will merely shrivel a small spot compared to the hypertonic solution. The murphy in the isosmotic solution will derive mass. and in two yearss the murphy gained 2. 3 gms.

My hypothesis was non right. It was wrong because I said that the murphy would spread out in the sugar when it truly shrunk the most. In my informations tabular array you can see that the hypotonic solution. the hypertonic solution had the biggest alteration in mass out of all the solutions. In my experiment I think that some mistakes that could hold occurred was. in the sugar solution on the 2nd twenty-four hours I saw that it had a bed of dried sugar at the top and most of the H2O was evaporated from the cup. The following clip I do this experiment I could set a palpebra or some kind of screen over the top of the palpebra so so less H2O will vaporize from the cup.
