How could I amplify a heartbeat for kids to hear quickly and easily, with or without a stethoscope?
Hi Everyone. Can any of you devise a way to amplify kids' heartbeats so that they are easily heard, without resorting to a stethoscope? Our school is having a fitness night...I thought it would be great to let each kid listen to his heart beat before and after jump-roping, but a single stethoscope would be too cumbersome to use-the kids don't have any experience with them...whereas holding up some kind of mic to their heart would be fun and fast. A quick amplified heartbeat would be best...either through a stethoscope or some other microphone arrangement. Any ideas? Thanks!
