The Virtual Oscilloscope replicates a real, physical oscilloscope, including having live sound input on browsers that support it. It can also be embedded on any web page. The tool enables learners to become comfortable with using an oscilloscope in their own time. Oscilloscopes are expensive, niche pieces of equipment and this free online tool completely lowers the barrier for learners to get to grips with how they behave and function.

Students first explore different materials to see what types reduce the most amount of sound when placed in a box. Each group is assigned a different material and they fill their box with that specific material. Students measure the sound level of a tone playing from inside the box using a decibel reader from outside the box. Students share this data with the class and analyze which types of materials absorb the most sound and which reflect the most sound.

QueSST will test technology to fly faster, quieter, and more efficiently, and data gathered from the X-59 will pave the way for commercial supersonic flight over land.

Students measure the wavelength of sounds and learn basic vocabulary associated with waves. As a class, they brainstorm the difference between two tuning forks and the sounds they produce. Then they come up with a way to measure that difference. Using a pipe in a graduated cylinder filled with water, students measure the wavelength of various tuning forks by finding the height the pipe must be held at to produce the loudest note. After calculating the wavelength and comparing it to the pitch of each tuning fork, students discover the relationship between wavelength and pitch.
