National Science Week – Doppler Rockets

Townsville State High School
36 Boundary Street, Railway Estate QLD 4810, Australia
The Doppler Rocket combines the elements of a toy with an audio Doppler shift to create an educational experience students won’t forget. The Doppler Rocket emits a true, sinusoidal sound waveform at a constant frequency of approximately 620 Hz. The circuit and speaker are housed in skinned foam that protects the unit during normal impacts. The circuit is powered by a 9 V battery. As the Doppler Rocket passes the students, they hear a noticeable shift in frequency. Velocities of 10 m/s can be easily achieved, resulting in a 20 Hz shift in frequency.
Students will be able to
- Fly It Horizontally (using handles and string)
- Swing It Overhead
- Play Catch
This will be operating in conjunction with the air rocket launcher where students can experience first-hand the operation and flight path of rockets and investigate projectile motion.
