Continuing on from the beginning of our unit on the science of sound that we started in Term 3, we discovered what sounds 'feels' like today using balloons, our voices and musical instruments.
Check out our discoveries below:
 |
| Taylor and Bella using vocal sounds to make the balloon vibrate |
 |
| Charlie, Asha and Livvy found out how big the vibrations got using a didgereedoo |
 |
| Foster, Hamish and Tessa giving it a go |
 |
| Does it still work if we don't touch the balloon with our mouths? |
 |
| Ollie and Leeroi used their biggest voices to create sound waves that transferred into vibrations |
 |
| William, Josh and Liam tried it out too |
 |
| What do you think they could hear in the balloon? Did it have anything to do with what Lorenzo is doing? |
 |
| Lily, Ella, Rachel and Anika discuss what is happening in their balloon |
 |
| Taylor and Bella then tried out transferring sound using the tin can telephones. Do you think it worked? |
 |
| How far away can you hold the balloon and still feel sound vibrations? |
Very interesting way to measure sound Room 3. What if you put some water in the balloon, or have you tried putting water into bottles and measuring whether different amounts of water contribute to differences in sound?

Thanks for making us think more about this idea Nicki and for sending in some balloons so we can try it out. We've put the videos up of us experiementing with balloons here
DeleteWhat did you feel when you made sounds near the balloons ? I so want to try it now ! And I want to try to see if there is a difference between high and low sounds. From playing my guitar I have a hypothesis that the low sounds will make the balloon vibrate more and more slowly and the high sounds well be faster and vibrate less.
ReplyDeleteCan you see sound waves ? How could you make the balloon write the sound waves ?
Great to see you all working so hard in week 1 !!!!
Cheers

Kia ora Gill,
DeleteThanks for your comments on our blog. We're trying to figure out what you mean when you ask 'how could you make the balloon write the sound waves'?
Could you explain what you mean?
I was thinking if it was vibrating it would be moving and if the balloon was moving it might draw a pattern.
DeleteI have tried it now with a balloon and I don't think it would move enough to be able to write.
Have you seen what vibrations look like ? Try looking at voice memo on your new ipads. Tell me what you think.
Cheers
Gill
We will give that a go when we have the iPads. Thanks for the suggestion Gill!
