Eric, Rave and Nikita Funnel ears Science experiment template

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)

Hypothesis: (What do you think will happen?) e.g. I think that...

Rave: I think that the sound will get worse.  

Eric: I think that the sounds volume will go up with the funnel facing to your partner

Nikita: I think that the sound will go worse.I think that the sound

Materials needed:

A Piece of Paper, tape and tissue or cotton.

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

Data (What happened?)

	Shape/object/materials	Results:
1	flat piece of paper	The sound was clear and didn’t make a difference.
2	funnel facing to the front	The sound was clear and it sounds like you turned up the volume.
3	funnel facing to the side	It sounds like you are inside someone else head and like you are whispering.
4	Tissue  blocking the narrow end of the funnel	It sounds like someone is whispering inside your head
5	rolled up piece of paper (facing to the front)	It sound like someone is talking to you but it sound like echoing.
6	rolled up piece of paper (facing to the side)	It sounds like someone is whispering to you.

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:

We have noticed that the sound is louder when it is facing in front of you. With all the experiences of the paper is turns out that it kind of makes a difference to the sound travelling to your ears. But from the different angles that we held the funnel the sound was different. Some sounds sounded like someone was whispering to or shouting to you from across the room.
