Unit 9: Radioactivity and Nuclear Energy
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 will be a couple of readings and 1 or 2 other WebAssigns.
There will be a quiz on this topic on Thursday, June 1. Keep a good
packet and you will have an effective study tool for that quiz. It will
be the last score of the quarter.
Information about the Final Exam will be available soon. 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

Mr. H's Little Secret
Pssss. Hey bud! I
have a secret to
share. Now that you know how to calculate the molar mass, here's a
little cheat you should be permitted to use. It's called the Molar Mass
Calculator and you will find it by following the links. You type in the
formula and it calculates the molar mass. (Revised links on 2/28/17)

- How about that Maker Fair?
- What is a radioactive decay series?
- What is nuclear bombardment and how can the nuclear change be represented as a balanced nuclear equation?
- What is the meaning of half-life and how can the concept be used to relate age and the amount of a radioactive sample remaining?
Shortened Periods - Honors and Awards Assembly
Block 3: 1:03 PM to 2:06 PM
Block 4: 2:12 PM ==> 3:15 PM

Time in Class
|>> Tuesday, May 30 <<
will review half life and half life mathematics. We will spend some
time discussing binding energy and nuclear stability. We may have some
time to discuss stellar evolution and nucleosynthesis.
