The straw Oboe.

Title of experiment: Straw Oboe Experiment

(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.

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.

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.
