Materials Required:
-
4 identical potted plants (same species and size; e.g., mung bean or money plant)
-
Ruler or measuring tape
-
2 speakers or headphones
-
Music source (mobile, speaker, or audio system)
-
Different types of music (e.g., classical, rock, no music, nature sounds)
-
Water, sunlight, and a controlled environment
-
Notebook for observation
Procedure:
1. Setup Groups
Label 4 pots as:
Group A: No music (Control group)
Group B: Soft/classical music
Group C: Rock/loud music
Group D: Nature/ambient sounds
2. Keep Conditions Constant
Place all pots in the same room with equal sunlight and water daily.
- Keep them at the same distance from the music source.
3. Play Music Daily
Play music for 1–2 hours per day at the same time for each group.
Group A receives no music at all.
4. Observe and Record
Record plant height every 3–4 days for 2–3 weeks.
Note differences in leaf number, color, strength, or overall health.
Observation Table (Example Format):
| Day | Group A (No Music) | Group B (Classical) | Group C (Rock) | Group D (Nature Sounds) |
|---|---|---|---|---|
| 0 | 5 cm | 5 cm | 5 cm | 5 cm |
| 7 | 6.2 cm | 7.5 cm | 5.8 cm | 7 cm |
| 14 | 7.5 cm | 9.3 cm | 6.4 cm | 8.5 cm |
| 21 | 8 cm | 11 cm | 6.7 cm | 10.2 cm |
Conclusion:
Plants exposed to soft or classical music and nature sounds grew faster and healthier than those exposed to no music or loud/rock music. This suggests that sound vibrations might influence plant metabolism or hormone activity, especially when gentle and rhythmic.
