Introduction Task Process Evaluation Conclusion

Introduction Nuclear chemistry is often one of the most misunderstood and feared subjects. We most often associate it with the atomic bomb, nuclear war and Chernobyl. While these problems are very important to the study of Nuclear Chemistry there also important and safe issues. Some of these include the use of Nuclear Chemistry in the fields of medicine, food preservation and power production. You are going to explore these issues and then make informed decisions about them. BACK TO BEGINNING

Task In this Web Quest you will be exploring the world of Nuclear Chemistry. • You and your group will be part of a Problem-Solving team who studies Nuclear Chemistry and the pros and cons that go along with it. • Each person in your group will become an expert on a particular topic within Nuclear Chemistry. You will decide this within your group. • You will then research all of the topics with the Internet links I have provided you. • After completing your research your group will get back together and write a letter to your congressman discussing whether funding should continue towards nuclear research. • You will then have an assignment to complete by yourself. You will need to choose one of the topics concerning Nuclear Chemistry and then choose to write either a Feature Article, Speech, or Persuasive Letter about it. BACK TO BEGINNING

Your job now is to get back together with your group and draft a letter to your congressman stating whether you think funding should continue towards the study of Nuclear Chemistry. After turning in your letter your next job is to write either a feature article, speech, editorial or persuasive letter related to any of the topics that were discussed on Nuclear Chemistry.

Evaluation Your grade will be determined by the completeness of the questions during the Process section of this Web Quest as well as the scoring of your group’s letter and your feature article, persuasive letter, speech or editorial.

Conclusion Now that you have completed this Web Quest hopefully you have a more thorough understanding of Nuclear Chemistry. With the energy crisis we are experiencing these issues will come up as we look for energy alternatives.
