No Oscilloscope? No Problem! Class Ideas for Visualizing Sound with Scratch and Free Tools<\/b><\/p>\n

Have you ever wanted to show students the volume or waveform of sound in a science class but found that professional oscilloscopes are just too expensive and complicated to use? Teaching students how to operate them can be a hassle, making it a high barrier to entry for classroom use.<\/p>\n

That\u2019s where a digital, oscilloscope-like teaching tool comes in handy! With just a PC or tablet and an internet connection, you can visualize changes in sound in real-time without any special equipment.<\/p>\n

Using Scratch to Visualize Sound in Real-Time!<\/h3>\n

Scratch is a popular programming tool used in elementary and middle schools. You can create a simple program using a microphone input to display sound volume as a real-time graph.<\/p>\n

Here’s a great example: oscillo_1<\/b>\u00a0 https:\/\/scratch.mit.edu\/projects\/18315338<\/a><\/p>\n

How to Use:<\/b><\/p>\n

    \n
  1. Turn on the microphone (you may need to allow permission in your browser settings).<\/li>\n
  2. Click the green flag.<\/li>\n
  3. Make a sound, and… a bar graph will appear and move!<\/li>\n<\/ol>\n

    Students will be amazed as they see the concept of sound volume visualized right before their eyes. This simple project is a perfect way to introduce or review the concept that “sound is a wave”<\/b> without needing any expensive equipment.<\/p>\n
