Happy to share glimpses from the #NewYear #VoiceCard making workshop conducted by #Kalpakghar at Pimpri Chinchwad Science Park and Planetarium 
#Visitors and #Educators loved this unique blend of science, art, and creativity where young participants recorded their New Year wishes and explored the #spectrogram of their own voice.
Through this activity, children visually experienced how a frequency vs time graph is generated, making #sound visible and meaningful with #SoundArt (NCERT/Class9/Chapter:Sound)
The spectrograms were then printed on pre-designed #NewYear cards, turning science learning into a memorable #STEMART.
Software Used during the workshop:
Audacity (For Voice recording)
Audacity is the popular audio editing and recording app.
Vocaroo is a free, web-based tool that allows users to record voice messages online without needing to create an account or install any software.
