Guiding Question: How does the density of a material affect the properties of sound traveling from a tuning fork?
Hypothesis: If the dense of the surface is high then the pitch will be lower.
Material:
Hypothesis: If the dense of the surface is high then the pitch will be lower.
Material:
- Tuning fork
- Two types of surface:
- wood
- glass
Procedure:
1. Take a pencil and a notebook before you get started with your experiment, because you wouldn’t want to miss something out, otherwise everything would be incorrect.
2. Take a tuning fork of normal size and hit it on each material. You should feel the vibration of the tuning fork while you’re holding it.
3. Get a timer/watch stop and time how long the tuning fork vibrates. Save your observations on a document or in your notebook.
4. Repeat the steps above.

Material | Observation |
Wood | Long vibration, lasts for long time |
glass | Annoying sound, loud and intense |
Conclusion: My hypothesis was right if the material has higher dense then it will have a lower pitch.
What happened to the data analysis? How do you know? What would you change about your lab procedure?
