A must for explorations of sound and waves, these rods are an easy way to demonstrate longitudinal waves as opposed to transverse waves.
They're ideal for teaching about nodes and anti-nodes in standing waves.
Our Singing Rods make a great addition to your lessons on sound and waves.
These magical rods will "sing" for you if you know the secret. Simply hold a rod between your thumb and forefinger at one of the three marked nodes.
Then rub that hand along the rod from middle to end.
And they're a great follow-up activity to see if students really understand sound and waves.
Place a little of the included special rosin on your other hand.
You get two rods (75cm and 50cm), so you can demonstrate the relationship of pitch to length.
