Ata and Martha 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)

It not that loud like a normal paper I have try it with the circle paper and it was a little loud. But not as loud as a normal paper.

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

You hear things like louder and sound like a robot. Might here and eco noise, sounds might reflect from the paper and might sound worse.

Materials needed:

Paper,Toshishes,sellatap

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	I didn’t make a difference, There was no excitement.
2	funnel facing to the front	It did and echo sound, You could hear a bit louder then you normally do.
3	funnel facing to the side	You could hear the person at less louder the usual.
4	cotton ball or tissue  blocking the narrow end of the funnel	It was twice as loud as we normal here.
5	rolled up piece of paper (facing to the front)	It was loud .
6	rolled up piece of paper (facing to the side)	It was the same as the one shape as a cone.

Observations:

When I put the piece of paper to my ear it didn’t make a difference. When I tried out the cone it sound louder. It goes with the rolled piece of paper. When we try out with the cone when we put the toshie it sound like baby voices.

Cutting the piece of paper it sound a bit loud but not as like the cone vision.

Conclusion:

It wasn't that clear but it was really sounding like a robot
