If you want to play an innocent April Fool's prank on someone, visit The Dialectizer website. It will take a website, (you must provide the URL address for it), and convert it to any one of these dialects: Redneck, Jive, Cockney, Elmer Fudd, Swedish Chief, Moron, Pig Latin, Hacker, or Censor.
Classroom Idea: Convert a website to a chosen dialect. Have your students read it so they can determine if it is a reliable source. See how long it takes them to figure out it the information is not reliable. Take note of their reactions and comments. Explain to them that not all websites are reliable sources and that anyone can post to the Internet. This is a good example on finding valid websites that are reliable and have creditable information.
Here is an example of the Elmer Fudd dialect.
You can also enter the URL address of a website and it will convert it to the specific dialect.
Here is a resource from Edutopia, April Fool's Day in the Classroom.
