An invention is something new that someone makes or thinks of. To invent things, inventors must first have ideas. They research each idea, and then try the ideas, step by step. Inventors learn from ideas that work, but they also learn from failed ideas. Failed ideas can help them come up with new ideas.

Some inventions solve problems. Some make things work better. Some inventions happen by accident. But all inventions have one thing in common—they all start with an idea.

Early motor cars were horse carriages with engines.

Chester Greenwood’s Cold Ear Problem

Fifteen-year-old Chester Greenwood lived in Maine. He liked to ice skate on freezing winter days. But he had a problem—his ears were always cold!

One day in 1873, he had an idea. Chester bent a piece of wire into a U-shape. He asked his grandmother to sew a pad made of fur on each end. Now he could stay outside and skate longer with his friends. His ears were warm and toasty!

Chester’s idea led to a new invention. Can you guess which one?

If you guessed earmuffs, you’re right!Chester’s friends wanted their ears to

be warm too. Chester started making more earmuffs. Soon Chester started selling them. He called them Champion Ear Protectors.

Today, every December 21, the people in Chester’s home town celebrate “Chester Greenwood Day” in his honor.

Mary Anderson’s Streetcar TripIn 1902, Mary Anderson had an idea.

It was a snowy day in New York City, and it was Mary’s first trip on a streetcar. Mary watched the driver shiver as he reached out to clear the snow that had piled up on the windshield. Mary took out her notebook and began to draw. She designed an arm that would swing back and forth on the windshield. The arm would be controlled by a lever near the driver inside the streetcar.

Mary’s idea led to a new invention. Can you guess which one?

If you guessed windshield wipers, you’re right! Windshield wipers have changed over the years. Today, every kind of vehicle has windshield wipers so that the driver can drive safely on a rainy or snowy day and keep warm at the same time.

Years later, another inventor tried to use Mary’s idea to invent windshield wipers for eyeglasses, but the idea did not sell.

Arnold Fornachou’s and Ernest Hamwi’s Accidental Invention

In 1904, Arnold Fornachou was selling ice cream at the World’s Fair in St. Louis, Missouri. It was a hot summer day, and he had so many customers that he ran out of ice cream dishes. The baker next to Arnold was named Ernest Hamwi. Ernest was selling very thin pastries. Arnold and Ernest decided to work together. They rolled Ernest’s pastries into a cone shape and filled them with ice cream.

Arnold’s and Ernest’s idea led to a new invention. Can you guess which one?

If you guessed an ice cream cone, you’re right! Since then, people have invented machines to make many different kinds of ice cream cones. The machines can make about 150,000 ice cream cones a day!

Ruth Wakefield’s MistakeIn 1930, Ruth Wakefield wanted to bake

a special cookie for her new restaurant. She started with her favorite cookie recipe. Then she broke a chocolate bar into small bits and stirred the chocolate into the cookie batter. She thought the chocolate bits would melt into chocolate swirls. But she was wrong! The chocolate did not melt completely. It stayed in the batter as little pieces.

Ruth’s idea led to a new invention. Can you guess which one?

13276_001-020.indd 1113276_001-020.indd 11 11/16/05 1:32:25 PM11/16/05 1:32:25 PM

If you guessed chocolate chip cookies, you’re right! Everyone loved Ruth’s cookies. They became very popular. The company that made the chocolate bar soon started making chocolate chips that people could pour out of the bag right into the cookie batter.

George de Mestral’s HikeIn 1948, while George de Mestral was

hiking in the woods, he noticed something. Small, prickly burrs from bushes he brushed against were sticking to his clothes.

Later, George looked at one burr under a microscope. He saw it was covered with hundreds of tiny hooks. The hooks had grabbed onto the loops of the fabric on his clothes. He realized that he could use this idea to fasten two things together.

George’s idea led to a new invention. Can you guess which one?

If you guessed Velcro®, you’re right!Velcro is made up of two strips of special

fabric. One strip has tiny hooks. The other strip has tiny loops. When the two strips are pressed together, they form a strong bond.

Velcro® is used on many everyday objects. Have you ever had Velcro® on your shoes? It is even used by astronauts in space.

Spencer Silver’s Failed IdeaSpencer Silver was a scientist in the

1970s. His job was to make a very strong glue. In the process of making the glue, something went wrong. Spencer’s idea did not work. He made a glue that was very weak. Some people thought it was useless. But Art Fry, who worked with Spencer, thought the glue was interesting. The glue could be applied to any surface and then be peeled off and used again. Art applied Spencer’s glue to some small slips of paper.

Art’s idea of using Spencer’s weak glue led to a new invention. Can you guess which one?

If you guessed self-stick notes, you’re right! Today, you can buy self-stick notes in every size and color. Some people use the notes for bookmarks. Some people write messages on them.

Next time you put a self-stick note on something, be sure to thank the scientists who didn’t throw away an invention that did not work!

Ideas can come at any time and in any place. Keep your eyes and ears open. If you excel at coming up with ideas, you just might create a few inventions of your own!

Now Try ThisThinking Like an Inventor

Inventors think of many ideas. Then they choose their best ideas and try to make them work.

Now it’s your turn to invent. Before you begin, think about this question: What are some everyday problems that need solutions?

13276_001-020.indd 1813276_001-020.indd 18 11/16/05 1:33:02 PM11/16/05 1:33:02 PM

1. Fold a sheet of paper in half. Write “Problems” on the left half. Write “Solutions” on the right half.

2. Now brainstorm! Make a list of problems and your ideas for solutions. For example, a problem you might think of could be finding the time to get your chores done, or your homework done. How could you fix these problems and make them fun to do?

3. Think of lots of solutions. Some won’t seem right. Some will sound pretty good. Some will sound terrific. Write down all of them!

4. Circle your best idea. 5. Draw pictures of how your idea might

look as an invention. 6. Share your invention with your class.

Here’s How to Do It!
