Experiment 8 Seed Germination

The experiment aimed to determine the conditions necessary for seed germination, specifically the need for air, water, and suitable temperature. Results showed that only the test tube with all three conditions (A) resulted in germination, while others did not. The hypothesis was accepted, confirming that these conditions are essential for seed germination.

年级： Junior 1 日期：

Title:
Experiments to determine the conditions for germination of seeds.

Aim:
To determine the required conditions for the germination of seeds.

Problem statement:
Are air, water and suitable temperature necessary for seeds to germinate?

Hypothesis:
Seed needs air, water and suitable temperature to germinate.

Variables:
a) Constant variable: Type of seed

b) Manipulated variable: Germination conditions

c) Responding variable: Seed germination

Materials and apparatus:


Boiling tube, cotton wool, water, cooking oil, sugar paper, green beans and refrigerator.

Procedure:

Figure 1 (a)

Figure 1 (b)
1) Four boiling tubes labelled A, B, C and D was prepared as shown in Figure 1 (a) and
Figure 1 (b).

2) Test tube A, B and C were put in the laboratory while test tube D was put inside a
refrigerator.

3) All the seeds were observed after five days for each of the boiling tube.

4) Observation was recorded in a table.

Result:

Presence of Seed germination


Test tube
Water Air Suitable temperature (Germinate/ Does not germinate)
A ✓ ✓ ✓ Germinate
B  ✓ ✓ Does not germinate
C ✓  ✓ Does not germinate
D ✓ ✓  Does not germinate

Discussion:
Seed needs air, water and suitable temperature to germinate. Test tube A act as a control
experiment which contain air, water and suitable temperature for seeds to germinate. The
purpose of using cooking oil in test tube C is to prevent air from entering the test tube.

Conclusion:
Hypothesis is accepted. Seed needs air, water and suitable temperature to germinate.
