Funnel paper, ears Experiment.

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 Each position would change. And I think that you can still hear but not clearly.

Materials needed: Tissue’s, Paper and tape to hold the structure.

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

Step 4 - When your partner Speaks, write down what it sounds like.

Step 5 - Switch position’s and see the difference.

Data (What happened?)

flat piece of paper
Nearly the same  as normal hearing
funnel facing to the front
Sounds loud and there's little sound in the background
funnel facing to the side
Nearly Clear but theres lots of sound in the background.
cotton ball blocking funnel
Still can hear but it you can’t hear what they're saying clearly.
rolled up piece of paper (facing to the front)
Very clear not muffed.
rolled up piece of paper (facing to the side)
Nearly the same as No.5. Not clear.

We had to get a flat piece of paper and it was nearly like normal hearing.Sounded funny because there was a little noise in the background.
.Was clear as well and there was also a little noise in the background.Was not so clear but you could hear properly, it sounded muffled Was very clear. Was nearly the same as No.5.

Through all the effort and hustle, we managed to finish our experiment. I found my hypothesis a bit right because when we changed the shape of paper and positions, the sound always changed.
