In science class we made our own stethoscopes and tested them . We used plastic pipes , tape, and either a plastic bottle top or a funnel. The most difficult part was getting a good connection between the pipe and the funnel or bottle top. We discovered this was also the most important part ! Some groups had to fix their connection and the trick was to use a pipe size that was a good fit with lots of tape. We used the stethoscopes to listen to heartbeats, pulse and digestion. Digestion was very noisy !! ( it was just after lunch break )
We tested the pipe end and the funnel end for listening.We also got to use a real stethoscope and compared to it our own stethoscopes worked well.
We did a class project on the heart and with help from everyone in our class we knew 41 facts about the heart. Thank you to Mrs. Mc Mahon who did a super job of displaying our project. Here are some photos ………
Listening to digestion ! Who has a grumbly tummy ?
