Explore internet resources to study the effect of humidity and temperature on the speed of sound, for example the PhET sound-waves simulation, Chrome Music Lab, and the Phyphox experiments.

Use the simulations to vary temperature and humidity and note that the speed of sound rises as either increases; summarise the trend with a short table or graph of your observations.
🔑 The Quest Continues…
Sound helps us explore beyond human hearing — space probes have recorded the first sounds from Mars, scientists time distant earthquakes to track ocean temperature, and researchers listen to soil microbes to study biodiversity. Keep listening and keep questioning!
