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?
