Badminton

This is my Presentation about Badminton this Term, I had lots of fun because it teached me good lessons about it.

Straw Oboe Experiment

Title of experiment: Straw Oboe Experiment

Question:

(What do we want to find out?)

We want to find out if its going to be loud enough for us and also what we want to find out if we put more straws will it be loud it will it still be the same as the first one, and if the sound goes deeper if we put lots of straw or will it be lower.

Hypothesis: (what do you think will happen?)

I think it will be really loud and it will vibrate into a person ear and it will go through there eardrum and it will go to there brain and there will do all the work. Also what will happened is that it will be really annoying because will always have to blow there straw oboe.

Procedure:

How will we find out?

(Step by step)

Is that first we grab a straw and a scissors and cut the top of the straw but we have to cut the sides and then we put the straw inside our mouth. And if we want to make even more better we can add some holes into it but it has to be small holes.

Results:

What actually happened When we put it to our mouth a sound came out it sounded like a beeping sound from a car horn I didn’t think that it was gonna work but it did at the end of it when we cut it shorter the sound became louder and lower it was so cool.

Conclusions:

We had to try it out to see if it will work or not and to see if it was loud enough for it to hear it. At the end we learn that it did work and the sorter you cut it the louder it gets for us and when you blow it hard.

Questions:

1. What is producing the sound? What producing the sound is that when you blow the straw and try to make a really weird sound and try to make it loud because Its really cool but also we are producing that sound.

2. What pitch did we get when all holes were closed, compared to when the holes were

open? Is when the hole were closed what happened is that when when went to blow it it sound really funny it but when you add the holes it is really cool because you can make your own sound.

3. What does opening or closing a hole in the straw really mean in terms of vibrating an

air column? Is that if we put holes on them it will still vibrate because it will vibrate under the straw because when we blow it the air will go under the straw.

Questions:

What happens to the pitch as you cut off pieces of the straw? Is that the pitch will go lower and lower because the more you cut it it will go lower and the more you even cut it it will go even lower. Why? The reason it will go even lower because how you cut it it goes even lower and lower.
