Temperature and Tuning Forks

Temperature and Tuning Forks | Science Fair Projects | STEM Projects
Ever wonder how temperature affects the sound of a tuning fork? In this project, you'll explore the relationship between temperature and the frequency of sound from a tuning fork.


The hypothesis is that the frequency of sound from a tuning fork will decrease as the temperature increases.

Method & Materials

You will vary the temperature of a tuning fork at 0°C, 25°C, 50°C, 75°C and 100°C, and measure the frequency of sound with a frequency sensor and scope.
You will need a tuning fork (640 Hz), a sound sensor and scope, a beaker, some water, a stove, a refrigerator, and an infrared thermometer.


The experiment showed that when the temperature of the tuning fork is increased, there is a slight reduction in the frequency sound generated. This proves that the hypothesis is true.

Why do this project?

This science project is interesting because it explores the relationship between temperature and sound, and how this affects the frequency of sound from a tuning fork.

Also Consider

Consider repeating the experiment with a tuning fork made from a different material, or with tuning forks of different frequencies.
