No Oscilloscope? No Problem! Teaching Ideas to Visualize Sound with Scratch and Free Tools<\/span><\/strong><\/p>\n In science class, have you ever wanted to visualize the “loudness of sound” or “waveforms” but found that a real oscilloscope is too expensive and tricky to use? Teaching students how to use it can be a real pain, making it a high hurdle to clear in the classroom.<\/p>\n amazon<\/a><\/p>\n Rakuten\u3000OWON Digital Oscilloscope SDS1104 1Gs\/s 100MHz Bandwidth<\/a><\/p>\n That’s where free digital oscilloscope-like teaching tools come in handy. Even without special equipment, if you have a PC or tablet and an internet connection, you can “visualize” changes in sound in real time.<\/p>\n \u3010Recommendation 1\u3011 Visualize Sound Loudness in Real Time with Scratch!<\/strong><\/p>\n Scratch is a classic programming tool for elementary and middle school. By using a program that displays microphone input volume, you can visualize sound loudness like a bar graph.<\/p>\n oscillo_1<\/a> \u3000https:\/\/scratch.mit.edu\/projects\/18315338<\/a><\/p>\n \u2022 How to Use:<\/p>\n Turn on the microphone (requires permission in your browser settings).<\/p>\n Click the green flag.<\/p>\n Make a sound, and… the bar graph moves!<\/p>\n Students will be amazed and captivated by how sound volume is visualized. This is a perfect tool for introducing or reviewing the concept that “sound is a wave,” without needing expensive equipment.<\/p>\n \u3010Recommendation 2\u3011 Free Web Oscilloscope “XXY OSCILLOSCOPE”<\/strong><\/p>\n If you want to see waveforms in more detail, this web app is for you.<\/p>\n XXY OSCILLOSCOPE\u3000<\/strong><\/p>\n![\"\"](\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2024\/07\/31ccfa716a3b8e5ec40ec06c2151608f.jpg\")
