Exploring sound in different ways
... talking to experts
Lucas: I’m so excited to learn about it!
Hugh: I think it’s something that you put on your heart to hear it.
Wilder: Sam, do you know something weird? The visitor’s name is called Sam!
We welcomed another expert to St. John's; our Brown Room teacher, Elena's partner, Sam Varney. Sam is currently a Medical student at Georgetown University and was excited to share more about the human heart with us. He brought a digital stethoscope, which is a medical tool that can amplify and record the sounds it detects. This way we were able to experience the sounds of the body collectively as a class. The children had many curious questions for Sam, about his stethoscope and the heart. Thank you for joining us, Sam!
Sam V: It has different parts.
Hugh: Put it in your ears.
Wilder: And the other part is for put it on your body.
Finlay: Put it on here (tapping his belly). On your belly and check your heart and hear how fast it’s beating.
Sam V: Yes, you can hear how it’s beating, your blood going through.
Wilder: Yours has a lot of ends.
Sam V: This is a special one. It has different listening ends. We call them diaphragms.
Michael: And these are the bones (pointing to his arm)
Wilder: Does one of the holes test your bones? Does one of the holes test your neck to hear your bone pump?
Sam V: It can also listen to your lungs and breathing.
Finlay: How does the beat get into someone’s body?
Hugh: Your heart.
Sam V.:What we hear is your heart opening and closing. So there’s two sounds that you hear.
Wilder: It’s going up and down and closing.
Michael: That’s a tapping thing (bottom of stethoscope, diaphragm?)
Luke: I can hear someone talking in your belly.
Finlay: The lungs talk. The lungs help you talk.
Sam V: You hear the blood going through. Like a waterfall makes sound, right? So that’s what you’re listening to.
Daniel: It’s not a waterfall.
Wilder: It’s like bood water inside your body.
Ines: Yes, your blood is going through your blood vessels, like rushing through it.
Wilder: Like rushing water.
Did you know your heart is about as big as your fist?
