Title: Bending Kangkong Stalk
Problem: What will happen to kangkong stalks when they dipped into water with
different compounds
Hypothesis: Type of compounds that affects the water potential of kangkong stalk
The type of solution and the water potential of kangkong stalk are
unrelated.
Materials:
Kangkong stalk
Blade
Salt
4 transparent glass cup
Spoon
Ruler
Water
Experiment/Procedure:
1. Gathering all the materials
2. Label the 4 transparent glass cup with A, B, C and D
A. Water with 1 tsp of Salt
B. Water with 2 tsp of Salt
C. Water with 3 tsp of Salt
D. Water
3. Select an internode of the kangkong stalk with a large diameter and cut out a
length of 3) mm using a blade
4. Cut the internode longitudinally into two halves
5. Then cut each half into 4 longitudinal parts to contain a total of 4 strips from the
whole internode
6. Observe the appearance of the strips after cutting
7. Place one strip into each cup with their corresponding compounds
8. Observe each changes every after 30 minutes
Analysis: Based on the analysis, the future course of action can be determined. If the
data found in the analysis is consistent with the hypothesis, it is accepted. If not, then it
is rejected or modified and analysed again.
