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 the sound of the paper will be a echo sound like in a tunnel.
Materials needed
Piece of paper and tissues.
Experiment (procedure):
e.g. 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 was clear and didn’t make a difference.
|
2
|
funnel facing to the front
|
It sounds like a echo.
|
3
|
funnel facing to the side
|
It sounds like you are inside someone else and like you are whispering
|
4
|
tissue blocking funnel.
|
It just sounded clear.
|
5
|
rolled up piece of paper (facing to the front)
|
It Sounded like I was having a conversation.
|
6
|
rolled up piece of paper (facing to the side)
|
I could just hear the sound in the background.

Observations:
It turns out that half of my hypothesis was right. When the paper was flat and Nikita spoke it sounded like Nikita and I were having a conversation. When we turned the paper into a funnel shape and faced it to the front it sounded like an echo. When we faced the funnel sideways it sounded like you were inside someone else's head and they were whispering. When we added a circle shape tissue at the end it sounded like someone was shouting to you across the room. When we rolled up the piece of paper facing the front it sounded like
someone is talking to you but echoing. Finally, we faced it to the side and it sounded like someone was whispering to you.
Conclusion:
Just Like my hypothsis was right. And my Observation.
