Plant Lab Report

Introduction: Define the problem

Problem: Is light necessary for the sprouting of a potato?

Hypothesis: If I put the potato in the dark, it will sprout.

Variables: Independent: Dark place
Dependent: Sprout



Constants (controlled): Same bag same temperature same kind of potato same dark same paper towel same water.
PROCEDORE

Materials: 1 medium size potato
2 plastic bags with twist ties knife
2 paper towels
Graduated Cylinder (for water)

Control of Variable:
1. Cut the potato in half.
2. Count the number of eye.
3. Fold each paper towel repeatedly.
4. Moisten the towels with water (5ml).
5. Place paper towel in each plastic bag.
6. Put the potato cut side, down the paper towel.
7. Tie each bags with twist ties knife(rubber band)
8. Place one bag in the light and one in the dark

Potato in light 5 4 5
Table2
Number of sprout Vivan&Polina Monica Jason
Potato in dark 0 6 10
Potato in light 4 4 0
Table3
Percentage of eyes Vivan&Polina Monica Jason
Potato in dark 0% 150% 91%
Potato in light 80% 100% 0%

DATA ANALYSIS

The effect of potato eyes sprouting in the dark V.S the light

CONCLUSION AND EVALUTION

The purpose of this experiment was to see the effect of the right compare to dark on the sprouting of potato eyes our data show that more eyes sprouted when the potato were in the dark, as seen on table 3 and graph A, This data support of our hypothesis.

EVALVATION OF EXPERIMENTAL DESIGN

In this experiment it was difficult to count the potato eyes and to get the same amount of water.

SUGGESTIONS FOR IMPROVEMENT

A suggestions to make the “eye counting” easier would be to use older potatoes that have not yet sprouted, to fix the water problem we should have use more water and measured carefully.



FURTHER STUDIES

Hypothesis: If I put the fertilizer in the potato, It will grow faster.

Variables: Independent: Add fertilizer Dependent: The growth of potato
