Visit the following site, and make some
observations about the type of information you
find there: Aluminum Foil Deflector Beanies
You will notice information found is well-
organized and the style of the page seems to be
professional, but upon further investigation,
some issues pop up…
The information here is not supported by
scientific fact, or by functional links, and the
author does not offer verifiable information
about his background

web site may be useful or not

By the end of this lesson, you will
be able to look at a site online and
determine if the site is reliable through
