Twenty years ago, kids in school had never even heard of the Internet. Now, I'll bet you can't find a single person in your school who hasn't at least heard of it.

So you have to be sure that whoever posted the information knows what they're talking about, especially if you’re doing research! But what if you're just emailing people? You still have to be very careful. If you've never met the person that you're communicating with online, you could be on dangerous ground! You should never give out any personal information to someone you don't know, not even your name! And just like you can't believe the information on every website out there, you can't rely on what strangers you "meet" on the Internet tell you either.
