Be Safe on the Internet pg. 93–94

Can I Trust the Information on the Web?
Do not believe everything you read on the Internet! To
evaluate the information you find on a Web site, ask yourself
these questions:
 Is the site’s creator reliable or unreliable?
Biased or unbiased?
 Can you contact the site’s creator?
 Is the site’s information current?
 Can you confirm the site’s information using
other sources?


Going Online

How Safe Is the Internet?
It is extremely important to protect your privacy online by
following these common-sense guidelines:
 Never give out personal information unless a parent
or guardian allows you to.
 Never give out your Social Security number.
 If you do give out personal information, make sure you
know who is receiving the information and that it
will be secure.
 Use different user names and passwords for
different sites.

B. Use the same user name and password to access
different Web sites.

While it may be easier to remember a single user name and
password, you should use different usernames and
passwords for different sites. That way, if an unethical person
discovers your user name and password for one site, he or
she will not be able to log on as you at other sites.

Project Assessment

Compare What is the difference between drilling down and
using a site map?

Drilling down involves opening links to other pages on a Web
site. In addition, each page may have links to more pages. A
site map, on the other hand, is like a table of contents for a
Web site. You can choose the page you want to view and go
directly to it.

Search the Internet Effectively, pg. 109–121
Project Assessment

Evaluate Why might you use a Boolean search
instead of a simple keyword search?

If a simple keyword search produces too many
results that are not specific enough, a Boolean
search can help limit the results to useful and
relevant Web pages.
