In the Singing Rods Demonstration Kit for physical science and physics, demonstrate resonance in a variety of different metal rods. Learn and remember important wave concepts including frequency, the Doppler effect and more.
A classic demonstration-times four! Demonstrate resonance in a variety of different metal rods. Which variables affect the resonating sound the most? Compare thick and thin rods, short and long rods, and solid and hollow rods. Will a hollow tube resonate differently than a solid rod? Position your fingers at different locations along the rods and hear the effect on the sound's frequency. Students will be fascinated by the range of frequencies and sounds they hear as you play the different singing rods. Best of all, students will learn and remember important wave concepts including frequency, transverse waves, the Doppler effect, resonance and harmonics! Four singing rods, enough rosin to perform the demonstration for years to come, and detailed instructions are provided.
