Conclusion

You might think that all the good things have been invented and that there is little left to invent. But that is not true. There is always a need to make things better. With each new invention, creation, and exploration, another is sure to follow. Maybe you will be the person who will invent the next product to make life easier or more exciting for us all!

Invention, Discovery, or Creation?

Have you ever wondered how an invention is different from a discovery or a creation? One way to find the answer is to look at the people. Explorers are people who discover. Astronomers explore space. They discover new stars and solar systems.

Creators are artists,

composers, and writers. They make works of art,

Van Gogh's self portrait

music, and stories. Vincent Van Gogh was

an artist who created fantastic paintings.

Beethoven was a composer who created

beautiful symphonies. William Shakespeare

was a writer who created great plays.

Inventors invent. They make things that they think make life better or work easier. Thomas Edison worked for thousands of hours inventing the light bulb. He was a true inventor and went on to invent many things, such as the first movie projector.
