🩹 Build a real working stethoscope from recycled materials and 3D printed parts!
Then use it to solve sound mysteries your ears alone can't crack.
What Students Will Do
- 🔧 Build a Real Stethoscope - Assemble 3D printed parts, recycled plastic, and beverage tubing into a working medical tool
- 👂 Test Everything - Try the stethoscope on tables, walls, water bottles, and anything else they can reach
- 🔎 Mystery Sound Challenge - Hidden sounds are sealed inside boxes - can you figure out what you're hearing using only your stethoscope?
- 💓 Listen to Your Body - Hear your own heartbeat race after jumping, listen to your breathing, and discover what your tummy sounds like
- 🏠 Take It Home - Keep your stethoscope and keep exploring sounds at home!
The Mystery Box Challenge
- 📦 Sealed Boxes, Hidden Sounds - Each station holds something making a sound too quiet to hear without your stethoscope
- 👀 No Peeking! - Your ears are the only tool allowed - press your stethoscope to the box and listen carefully
- 🤔 What Could It Be? - Is it crackling? Ticking? Rushing? Fizzing? Every box sounds different
- ⌛ Can You Listen to Time? - Some sounds will surprise you - you've never heard anything quite like this before
- 🎉 The Big Reveal - After everyone guesses, we open the boxes together!
What Students Will Learn
Sound & Vibration
Everything that makes a sound is vibrating - your stethoscope helps you hear vibrations that are too quiet for ears alone.
Tools Extend Our Senses
Doctors use stethoscopes because some sounds are too quiet to hear without help. Tools make us better observers!
Careful Observation
Scientists don't just look - they listen, compare, and describe. That's exactly what Sound Detectives do.
Making from Recycling
Your stethoscope diaphragm comes from a yogurt lid! Everyday "trash" can become real, working tools.
Made from Stuff Around the House
- ♻️ Recycle #5 Plastic - Families send in a clean yogurt lid or deli container lid (polypropylene) - it becomes the stethoscope diaphragm!
- 🍻 Beverage Tubing - The same soft, flexible tubing used in soda fountain machines worldwide
- 🛠️ 3D Printed Parts - Chest piece and connectors printed right here in our maker lab
- 🔊 Real Ear Tips - Comfortable, extra-small ear tips sized for young ears
Designed for Little Makers
- No Cutting, No Sharp Tools - All materials are pre-cut and ready to assemble
- Snap & Push Assembly - Parts connect by pushing tubing onto connectors - small hands can do it!
- Comfortable Ear Tips - Extra-small tips that sit gently - no need to push them in
- Body Listening Over Clothes - Heartbeats and breathing are heard right through shirts
- Supervised Stations - Mystery boxes are staffed so every child gets guided through the experience
Why Schools Love This Workshop
