Phonograph recordings



Telephones



Computers



Cars



Televisions

The flush toilet has remaine pretty much the same since it was invented by Thomas Crapper

The Evolution of Useful Things by Henry Petroski is a very good book on the changes in things from forks to pins to paper clips to zippers. You may be able to get a copy through your library.

EVERY invention goes through numerous changes. I can't think of any that didn't, including the flush toilet.

The phone may have... There were the big ones that only worked on the wall and now there are cell phones! Hope you do good on your project!
