Sound

We have finished our topic on "Exploring Sound". Let us know what you learnt.

Creating a Soundscape

Mrs D wrote a story for us and we drew a soundscape picture of what it sounded like. Then we created a piece of music to tell the story.

Here are our pieces of music.

What did you enjoy about our soundscapes?

Our musical stories about a storm

Our task was to create a musical story about a storm. We were only allowed to use our bodies to create sound.
We had to think about soft and loud sounds and what parts of our bodies would make each sound.

A really cool song about sound!

Sounds – Lyrics

Well now sounds are made, when objects vibrate
It’s not something you can always see
But air vibrates so make no mistake
That’s the sounds you hear, solid, liquid and through air
And it’s entering your ear, come on I know I’ve made myself clear

The pitch of the sound, how high or how low it goes
A short string gives a higher pitch sound
A tighter skin makes a higher sound on the drum
Now come on! Come on!

Well now sounds are made, when objects vibrate
It’s not something you can always see
But it is something that will always be
I know I’m not but if I was
An astronaut in space I couldn’t hear anything
It’s a vacuum the sound has no trace x2
Come on! Come on!

The sound has no trace
Now sounds are made, when objects vibrate
It’s not something you can always see
But air vibrates so make no mistake
That’s the sounds you hear, solid, liquid and through air
And it’s entering your ear, come on I know I’ve made myself clear

Well now sounds are made (I know I’m not but if I was)
When objects vibrate (An astronaut in space)
Well now sounds are made (I wouldn’t hear any thing)
When objects vibrate (It’s a vacuum the sound has no trace)

What we have learnt about sound so far...

Victoria meant to say on the voice that the person at the back of the field can still hear the sound but after the closer person.

Sound can travel through water, air and solids.

We have just watched a video on sound (see our science tab on our class blog above) and have also learnt....

• Sound travels as vibrating waves called sound waves (Courtney)
• Some older people can't hear high sounds because they have damaged their hearing over time (Megan)
• Sound can be high and low (Makayla)
• Light travels faster than sound (Ashton)
• The longer the tube the lower the sound (Fin)

Making musical straws

Today we made some musical straws. This is how we made them...

1. Flatten one end of the straw.

2. Cut the corners to make an upside down V

3. Blow through the tip of the straw to make a sound

4. Cut the bottom of the straw shorter and shorter and keep blowing

What did we notice?

The straw made different sounds.

As we cut the straw shorter the sound got higher and higher.

Shorter = high sound, Longer = lower sound

We found out that to make the sound the air inside the straw was vibrating.
