Unit 9: Radioactivity and Nuclear Energy

Unit 9 is on the topic of nuclear radition and nuclear energy. We will learn what nuclear radiation is and how it is used for both bad and good purposes. It will be a shortened due to the end of the school year. The actual schedule for the remaining days is listed below on this page.

There are two Reading Guides and two other non-Reading WebAssigns. There will be a quiz on this topic on Thursday, May 31. It will be the last score of the quarter.



Final Exam

The Chemistry Final Exam will be during the Block 1 time slot in the Lyceum on Monday, June 4. It will be only mildly cummulative. That is to say that content learned first semester will be on the Final Exam. However, it is the first semester content that was repeated during second semester or incredibly important that will find its way into the Final Exam. Most questions will be based on second semester content.

Relative Abundance of Radioisotopes

As we discuss radioactivity, radioactive decay series, and the relative abundance of radioisotopes, we will be looking at the following data:

FREE: A Chemistry Study Tip

Stretching out your studies over a lengthy period of time so that there are many "visits" of the material is far better than lengthier, less-frequent sessions of intense studies. So what's this have to do with Chemistry class? I'm going to tell you:

A little Chemistry each day helps. Your homework usually includes two WebAssigns - one is a "looking ahead" WebAssign in which you read about something that is coming up next. The other is a "looking behind" WebAssign in which you practice using something that we just learned in class. So why not do the "Looking behind" WebAssign on the evening of the Blue day - the day you were presented with the material. And then do the "Looking ahead" WebAssign on the evening of the Gold day - the evening just prior to when we cover the material the next morning. Hopefully that makes sense ... and it gives you a little Chemistry every day.  =SIGH=
