Can a straw be altered so that it will produce a sound, and can the pitch of that sound be affected by the length of the straw? Yes it can because the shorter the straw the higher the pitch the longer the straw the lower the sound. I found out this Information by trying the experiment, my self so I know that it works! ...Kayla P.

On January 12, 1999 we used straws. We were trying to find out the different sounds from longer and sorter straw lengths. What you had to do is cut the end of the straw and cut it shorter and the shorter it gets the higher of the pitch you get. It's fun in ways. ...Kris

In science class yesterday we did a straw observation. We cut the straw like a reed and tried to make a sound. Mrs. Eldridge couldn't make a sound, but the rest of the class could. Maybe it was because she had asthma, or could not blow hard enough. The reason we did this project is so it would help us on the meaps. ...Jessica

Yesterday our class did a meap experiment with straws. It was very fun & very loud. What we had to do was cut a sort of reed out of the straw so it made a noise, then we cut three cm. off it to make higher pitches, and louder noise. Then we had to record everything we learned in the booklet. I think this experiment was a great success and the class loved it. ...John

The day we blew out our ears

In science class we learned that you can make sounds through straws. These are some ways you can make sounds through straws, blow over the straw, drill holes in the straw like flute. I think I'm going to try that, drill holes in the straw.

I think our teacher got a headache. I know my mom would. At first I did not get how you blow in it, but then I got it.

This is one of the things I learned is that the longer the straw the lower the pitch. The shorter the straw the higher the pitch. This was one of my favorite experiments. ...Ryan

In science class yesterday we did an experiment with rubber bands and straws. We answered the questions in the straw instrument investigation journal. We all tried to answer, Can a straw be altered so that it will produce a sound, and can the pitch of that sound be affected by the length of the straw? Then we started the fun. We made sharp cuts into the straw so that it was like a reed. And so we learned that the longer the tube the lower the pitch and the shorter the tube the higher the pitch. I thought that the straw experiment was fun. ...Cari

The question we investigated was " Can a straw be altered so that it will produce sound and can the pitch be affected by the length of the straw." I new by blowing across the straw would make sound, but we did it another way. In the end our room was loud enough to shatter the windows. In my opinion it was very fun and would do it again. ...Ty

Can you make a straw make a high or low sound? We did in our 5th grade classroom. The majority of the class though that as you cut off more of the straw the sound that the straw produced would become a higher pitched. Here are a couple more ways we though you could make noise from popcans by blowing across it, and filling it with water and hitting it with a stick. What we though about the shorter the straw the higher the sound was right. You should try to make higher and lower pitch with different things too. . .. Clinton

The class and me did a straw experiment. It was for the meap. We found out that the shorter the straw was the higher the pitch was. You had to blow hard to get the sound out. It vibrates on my teeth and tongue like a reed of on a clarinet. I really like doing this. ... Emily E.

Straw Experiment

The question was could a straw be altered so that it will produce a sound and can the pitch of the sound change? The answer is yes you can make noise and change the pitch of the sound. ...Jordan

The answer is you can make a straw make a sound and, you can make the pitch higher or lower. We did this experiment by making the straw smaller and bigger and blowing threw the straw. ...Tim

#1 First we took straw and flatten one side of the straw. #2 Use scissors to make the flattened end look like a reed on an instrument. #3 Put the straw in your mouth so the reed is covered. #4 Blow into the straw and listen to the pitch. #5 Cut off three centimeters. #6 Keep blowing and cutting until 6.5 centimeters is left. You'll learn that either shortest the highest or shorter the lowest. It can be very helpful cause you can use it for a duck call. ... Cheyenne

A while ago our class did an experiment with straws. First we had to design a question our class question was, Can a straw be altered so that it will produce a sound, and can the pitch of that sound be affected by the length of the straw? Secondly we had to find out what we already know about the question some said if you blow over the top of the straw like a pop bottle you get a sound, others said that if you blow though the straw you'll get a sound. Last we had to make a chart saying when we got the lowest sound and highest sound. We had lots of fun doing this experiment and we hope to do it again. ..Curtiss

The day my teacher got a headache

In science class we learned that the length of the straw can alter the sound it will produce. We had to predict if the sound would be a higher pitch if the straw were short, or if the pitch would be louder if the straw were longer.

Well, of course, our teacher cannot teach a lesson without doing an experiment. She showed us how to cut the straw so the straw would act like a reed. She tried to blow through it, but she couldn't make any sound. She then said- "lets see if anyone can make the sound in this room, I know it is possible, but I can't do it to prove it to you."

1...2...3...! Everyone started to blow on the straws and sure enough- out came a low or high a pitched squeak depending on the length of the straw. That minute I knew that my teacher had a headache, and boy did I feel sorry for her because we knew she had another science class to teach and it would be on the same thing, the straw experiment. ...Chelsea

In our class we did some stuff with straws, like see if we can make a sound come out. First we had to write a question which was, "Can a straw be altered so that it will produce a sound and can the pitch of that sound be affected by the length of the straw?" Then we had to tell what we already know like, (Making a sound by blowing though the tip of the straw.) Next we had to tell what we think will happen. I put down, "I think the sound will be different by the length of the straw." Now we get to do something with the straws. First we had to cut the reed end. After we were done with that we had to blow though and it made a big and a really weird sound. Our teacher couldn't make a sound but everybody else did. Then we had to make four line and make the straw shorter. That didn't work for me. Next we had to tell what the results were. Then the answer to the question. Our last step was to make some kind of bar graph. ...Mandie

We had a very fun day in school. We were doing an experiment of straws. We liked it because it was very loud in the class because we needed to guess if the straw made a sound. There were steps to make the straw make a sound. Here are the things you will need six plastic drinking straws, straw instrument investigation journal, centimeter ruler pair of scissors and a dark marker or felt-tip pen. Here are the steps in order. First, you needed to flatten the end and cut with your scissors to trim the end so it could make a reed. Second step is use a marker that is dark to make lines three centimeters apart. Third step is to put the straw in your mouth completely. Fourth step is to cut three centimeters off a straw. Fifth step is to repeat the step of fourth. I am done telling you all the steps of the meap test. The experiment was not hard but it was very fun. We all were in teams in the meap test. ... Jose

Our class did an experiment with straws. The question was, can a straw be altered so that it will produce a sound, and can the pitch of the sound be affected by the length of the straw? The answer is yes. If you cut the end in a certain way it acts as a reed and makes a noise. The longer the tube the lower the pitch, the shorter the tube the higher the pitch. Everyone in our class that could was buzzing away and it gave our teacher a headache. It was a lot of fun buzzing because if it touched your tongue with the end in your mouth it tickles you tongues. Then we had to go to our next class and we had to stop buzzing. ...Ginny
