Persuasive Writing: Amazing Inventions!

 To celebrate Thomas Edison's birthday, students were asked to come up with an invention they thought could change the world for the better.  To convince the reader that this invention is an absolute necessity (and perhaps even possible!), they had to write a five paragraph essay outlined like this:

I. Brief Intro on the invention, perhaps including a scenario or hypothetical question

II. More detail on how the invention would work

III. Whom this invention would benefit

IV. Extra details (cost, size, various options)

V. A conclusion sentence with a snappy "sell it" sentence.


Enjoy these samples!  I bet you'll want to buy these inventions to have for yourself!


 CancerCancelator2000

By Adeline (4th grade)

If I could create a new invention, it would be the “CancerCancelator2000.” My invention would be able to cure cancer using a laser, and you would save a lot of money doing it. Then cancer patients wouldn’t have to worry.

The “CancerCancelator2000” would be easy to use. It is a two inch long device, and if you press the on/off button, it turns on or off. If you press the yellow button, a dark blue laser shoots out. When you aim it at the cancer patient, the tumor will disappear, and they will be healthy again.. 

This invention would help cancer patients. If they are sick, they will get better. Doctors are helpless in curing cancer. This invention will make things easier and will save a trip to the hospital. 

The “CancerCancelator2000” comes in any color, and is only $11.99. Returns are allowed, but you won’t need to return it because this invention is so helpful. The “CancerCancelator2000” is very obliging and will help you save money. When it cures the person, confetti shoots out to celebrate! This will make the cure even more exciting. 

This invention will help many people and hospitals. And it is not expensive. Buy it to cure cancer!



"The Personal Temperature/Weather Control," by Jayden (5th grade)

If I could create a new invention, it would be the ‘Personal Temperature/Weather Control™’. Have you ever overheated in a greenhouse on the equator or hypotherminated on the North Pole? Or maybe just wanted to change the weather for your own well-being? Well, there isn’t any way to control the natural weather, but you can control your own personal weather/temperature with this new invention!

All you need to do to use the Personal Temperature/Weather Control™ is to push the power button. Because your neurons communicate with electrical signals, the Personal Temperature/Weather Control™ can detect them. Using a lot of AI training, it can detect what you are thinking. After this stupendous invention reads your mind, it automatically changes your personal weather/temperature to what you want. You sense the whole world as it would be if it were the weather/temperature that you want. For example, you could be in a snowstorm but want a sunny, warm, but not too hot day. You think, “I WANT A SUNNY, WARM, BUT NOT TOO HOT DAY!!!” The Personal Temperature/Weather Control™ then reads this and changes your weather to a sunny, warm, but not too hot day. This means you can see no snow at all, feel it, or interact with it, but instead feel and interact with a sunny, warm, not too hot day. This invention does not affect any other people’s senses or weather(for anybody who is absurdly evil and wants to control the whole world’s weather).

This invention would help people who like outdoor spaces, but hate the weather. Also, people who live in extremes could use this, for THEY could definitely live at the North Pole or in a greenhouse on the equator. And everyone has experienced guessing wrong with the daily weather, or ignoring the forecast altogether.

The regular price of the Personal Temperature/Weather Control™ is $50. If you want others to see your weather (maybe on a very bad day), you can get that version, which costs $10 more. Also, you can switch it off if you want your weather to be private. Another option is the tints modification, which can give your world any color tint. This costs $10 more. The last version you can get is the day/night version, which costs $15 more. These additions are all stackable.

Everybody has experienced a situation where they hoped that winter was warmer or that summer was cooler. By using the Personal Temperature/Weather Control™, every single aspect of the unreliable, natural weather could be changed into a blissful, realistic version of the earth!



 The Lost and Found KeyChain

 by Jessie (5th grade)


Have you ever lost something and felt depressed about it? My newest invention, “The Lost and Found KeyChain.” will fix that. A “Lost and Found KeyChain” is a small convertible keychain that when you click a button, your lost object, as stated in the name, will be found.


This Lost and Found KeyChain would be extremely simple to use. First, when the owner of this keychain realizes they have misplaced an object, they would simply take out their keychain and press the a button. Take into consideration that there are two buttons: the blue one is for finding a person, and the purple one is for finding an object. After pushing the a button, make sure to say what you want to find, or else your KeyChain will give you everything anyone has lost. Thanks to the mechanical functioning in the KeyChain, your lost objects won’t be lost for long.


This creation will help all the kids or grown-ups find their lost objects. The sadness in your mind for losing something valuable to you will soon be replaced with the joy of getting it back. A lost cell-phone, Apple Pencil, water bottle or even sibling at a busy amusement park, will all be solved with my creation. But the “The Lost and Foundkeychain” does not only specialize in finding objects, it also helps find people!  For example, have you ever seen a parent running around, terrified trying to find their kid?  Well this little piece of backpack decor will fix it all up. “The Lost and Found KeyChain” would save so much money otherwise spent replacing important objects, with just a push of a colorful button.


For only  $4.99, the “Lost and Found KeyChain” not only provides you with the joy of finding a lost object or person, but so much more. This keychain can come in customized colors of your pick on a website for free. From red to purple, and gold to silver, this KeyChain can also come in the form of a bracelet, necklace, headband, choker and even anklet. 


The Lost and Found KeyChain can help even the clumsiest person find their lost objects. Next time you wish upon a star to find your lost object, you know that you can just wish upon a The Lost and Found KeyChain.
