# Science Experiments with A Drinking Straw

Updated on July 1, 2011

## Kids Science Experiments

There are many different easy Science experiments that kids can do with just a regular plastic drinking straw. You can find some different projects that are easy and fun in Science Experiments Using Straws.

We know that straws were invented by Marvin Chester Stone in 1905

We learned from other science experiments thatÂ  from a simple plastic drinking straw we can make a medicine dropper, a perfume atomizer and make a spray water bottle. Read more for some other straw science experiments.

## What is A Straw

Teaching kids about science and straws let start with the fact that a pipette, a tube that scientists use to measure and transfer liquid from one container to another works the same way a straw does.

Here we will see an experiment using a straw to produce sound waves and see how wheels make work easier with friction.

Nobody completely understands what causes friction but with this easy science project you can see and learn by doing.

## A Straw Turns into A Trombone

With a soda bottle, some water and a straw you can make a slide trombone. By submerging one end of a straw in water and blowing across the other end, you can make the air inside the straw vibrate and, in turn, produce sound.

## You will need:

• a straw
• water
• a soda (or any bottle)

What to Do:

• Pour water into the bottle until it is about 3/4 full.
• Put the straw in the bottle. Blow across the top of the straw in the bottle.
• Then either lower the bottle or lift the straw and continue to blow.

## What Happens:

As you lower the bottle, the sound gets lower in pitch.

## Why:

You are lengthening the column of air in the straw. This is how a slide trombone works. The movement changes the length of the air column in the straw. The longer the column of air, the longer the wavelength and the lower the frequency of the sound waves. The lower the frequency of the sound waves, the lower the pitch.

## Straw Wheels

Do wheels make work easier?

Lets see . .

## What you need:

• 2 Straws
• A book

What To Do:

Place a book on the table and try to push it. Then place the straws on the table andÂ  put the book on top of the straws. Push the book.

## What Happened to the Book:

Without the straws, you need to push hard to move the book. With the straws, the book moves more easily.

## Why:

when one item rubs against another, it resists moving because both surfaces are not completely smooth, The bumps of one surface the book catches the bumps in the other the table,. The amount of resistance, known as friction, depends on the kinds of surfaces and the forces pressing them. The rougher the surfaces, the greater the friction. Rolling results in less friction than sliding.

Cags - wow . .that is big hearing those words from you! More science to come. . thank you for these words here:)

Coolmom - and it is from when my daughter was in grade school that I am pulling these ideas out from. I forgot how much fun we had . . thanks for coming by. . you really are a cool mom:))

I enjoyed reading your article, reminds me of elementary school science projects.

Hey Shari, that was a pretty cool hub. Found it a great read. I'm headed over to your other hubs on science. You did an excellent job on presentation. Thank you. :)
