Science experiment:
Question: What will happen to the sound if I change the shape of a piece of paper? (e.g. from a flat shape to a funnel shape)
Links to research about Sound:
Hypothesis: (What do you think will happen?) e.g. I think that….
I predict that when you make a funnel shape, it will be louder than the flat shape.
Materials needed:
paper and sellotape and tissue
Experiment (procedure):
Step 1 - First hold a flat piece of paper against your ear. Block your other ear with your hand. Get your partner to speak to you. What is the sound like? Can you hear clearly?
Step 2 - Next, roll the piece of paper into a funnel shape. Put the funnel against your ear. Face the funnel towards your partner and listen to them speak. What does it sound like? Can you hear clearly?
Step 3 - Next, face the funnel to the side while your partner speaks to you. Does it make a difference to the sound that you can hear?
Step 4 - Put some cotton balls or tissue paper into the funnel to block one end. Does it make a difference to the sound you hear?
Step 5 - Next, roll the piece of paper up and l

Results:

1
|
flat piece of paper
|
It didn’t make a difference
|
2
|
funnel facing to the front
|
It was loud and clear
|
3
|
funnel facing to the side
|
It wasn’t clear it wasn’t loud it just sounded blurry
|
4
|
cotton ball blocking funnel
|
It sounded like someone speaking while my ears were blocked
|
5
|
rolled up piece of paper (facing to the front)
|
It was loud, and my ears were sore
|
6
|
rolled up piece of paper (facing to the side)
|
I couldn’t hear my partners voice, I just heard everyone in the background.

Observations:
I just realized that when you roll up a paper and someone talks through it it will sound really and it will hurt your ears .
Conclusion:
The flat paper will not be loud. But then when you roll it up, it will sound really loud. So I guess that my prediction was wrong. The funnel paper wasn’t loud, it was the rolled up paper.
