Not all inventions have such profound impacts on life, but they can make our lives easier or at least some people's lives easier. And even if they don't, the inventor can gain a sense of accomplishment and gratification.
If your child is curious and creative, he or she just might have what it takes to be an inventor. Some inventors seem to be born to invent (like Edison), but children can learn to how to approach problems like an inventor. Even if your child doesn't become a rich and famous inventor, he or she can have lots of fun!
