Tap to Learn the Meanings!
- changed: When something becomes different from before.
- comparing: Looking at two things to see how they are the same or different.

Now you can use these words to talk about how sound travels!
Sound Travels
Sounds move away from a sound source.
Listening With Our Ears
We hear the sound when it gets to our ears. We call this listening.
Let’s Investigate!
Question: Does sound change as it moves?
You will need: a triangle or other instrument
The children are doing an investigation.
Thinking Questions:
1. Who will hear a loud sound?
2. Who will hear a quiet sound?
They are comparing the sound in different places.
Method:
- Try doing this science investigation.
- Stand in different places and compare the sound you hear.
- The sound has changed if it is different in different places.
- Try using different sound sources.
Safety First:
- Do not stand near to a very loud sound. It is not safe.
- It can damage your ears.
How am I doing?
Do you hear the change in sound? Listen carefully.
Is it a big change or a small change?
Show how loud the sound is in different places with your hands.
Well done for comparing sounds carefully and thinking like a scientist!
Near Sounds Louder
When you are near to a sound source the sound is louder.
Far Away Sounds Quieter
When you are far away from a sound source the sound is quieter.
