Craft a Simple Stethoscope

Materials Required:
Plastic funnel
Cardboard tube
Tape or glue
Scissors
Steps Involved:
Attach the wide end of the plastic funnel to one end of the cardboard tube using tape or glue.
Ensure the connection is secure and that the funnel is positioned snugly against the tube.
Use the stethoscope to listen to different sounds, including your own heartbeat or other sounds around you.
Discuss how a real stethoscope works and how it helps doctors monitor the heart and other body sounds.
