Introduction
'What does this subject have to
do with me?' This is an important question students sometimes ask. But
answering the question isn't always easy as each different 'me' might relate
to or connect with the topic in different ways. The following activity
is what's called a Subject Sampler. The idea of a sampler is that people
who are given the choice will choose things they like or are curious about
trying. Boxes of chocolates, compilation CD's, and smorgasbord buffets
all work on this principle. In the following activity, you'll find links
to Web sites related to the topic of Asteroids. After each link are three
prompts designed to get you to answer one question: 'What does this subject
have to do with me?' After all, you can answer that better than anyone
else.

Conclusion
By now you should have a better
idea how this topic does relate to you. This Sampler was created because
although it's important to learn information about things and to think
critically about subjects, further learning doesn't always take place if
a personal connection doesn't first exist. We hope that through this Sampler
you've found such a connection. If you have, maybe you're motivated to
learn more? The Internet and traditional resources offer plenty of other
choices to explore on the topic so why not follow your interests?
