How Do We Use Sound? – Our Guest Speakers

Special thanks to all our wonderful guest speakers who came in to share with us how sound is used in their field of work! We had the honour of having a doctor, police officer, early years teacher, yoga instructor, musician, and learning support coordinator.

Doctor: Students learned that doctors use a tool called a stethoscope to find out information about our bodies. They really enjoyed listening to own and friends’ hearts: “It is so LOUD!”

Student Reflections on Learning:

Doctor listens to your heart (Sienna). 

Your heart is inside. Doctor has to use the instrument to hear it (Win).

When someone is sick, the doctor listens to find out why he is sick (Joon).

If your heart is sick, you can die (Win).

They listen to your stomach too (Poh).

When I am coughing, doctor listens to my chest and my back and checks my throat and ears (Robyn).

I could hear my heart (Summer).

Patient is someone who is sick (Ryu).

Doctor is listening why we are sick (Vincent).

Police: Students learned that a police officers use walkie-talkies, as a communication device, to exchange information to other officers within the same vicinity.

Student Reflections on Learning:

The police men are using walkie-talkie to talk (Pokpong) 

To talk to other policemen (Berci).

To call them? To tell other police men where the bad guy is, if they see him (Arth).

Walkie-talkie helps police to hear each other (Nathur).

Others, who are not the police, cannot hear it (Win).

Police use a special phone to talk to their friend policemen (Pun).

Listening to walkie-talkie (Kajorn).

Musician: Students learned that sound happens when two objects come into contact with each other. Also, that the force at which something comes into contact with another object will determine the volume, pitch and tone of the sound. We have also explored why people play or listen to music.

Student Reflections on Learning:

The guest speaker played us a song (Vincent).

He was making different sounds (Chaosub).

We listened to the orchestra on the smart board (Vincent).

He played the violin (Sienna).

Music people show us how to play music (Joon).

They play music because they love to listen to music (Summer).

Songs make you feel sad or happy (Ryu).

People like to listen to music so musicians play music for them (Arth).

Yoga instructor: Students learned the power of silence and meditation. Our guest speaker showed us how to play many games which require no sound. And by doing these activities, you can improve your focus and concentration.

Student Reflections on Learning:

Yoga teacher taught us yoga (Nathur).

How to balance (Win).

Different positions. I liked yoga teacher (Chaosub).

We used a bell  (Shiryu).

Walking with a bell but no sound, carefully (Ryu).

Yoga was fun! (Tara)

Teacher: Students learned that Early Childhood teachers as well as mothers are able to use the sounds that babies make to understand what the baby is trying to communicate. For example, “neh” means the baby is hungry and “owh” means the baby is sleepy.

Student Reflections on Learning:

Baby sounds were different (Robyn).

They were sad (Ryu).

They were crying (Vincent).

Baby wants to get something but mommy and daddy don’t know what it is, so baby cries (Win).

When baby cannot talk they can use their hands to show (Summer).

Learning Support Coordinator: Students learned that children that are challenged in speech can use machines which are able to speak on their behalf. Students also explored an app which allows the user to form sentences through images and prerecorded words.

Student Reflections on Learning:

When you cannot talk, you can click a button on computer and it will speak for you (Joon).

These children can’t talk but they are very smart (Robyn).
