First we did a lab to determine the half-life of cornium atoms.   Make sure you have completed this lab with a graph, data table, analysis and follow-up questions and turned it in.

Next we did a practice quiz on radioactivity.   The key is found HERE.  We will have an open notebook quiz on radioactivity on Monday.

 Today we took some notes on radioactivity and half lives.  See Tyler's videos for help with this concept

Next we did some practice problems found HERE.   Check your answers HERE and HERE.   Finally we watched a video on the most radioactive places on EARTH:

 Today we wrote the Chemistry Unit test.   Nice work balancing all those equations and compounds......👏💪. Next read and take notes on pages 222-223 in your text as well as 228-230.  Turn these notes in.  

Have a great weekend!

Today we did the lab 8A (posted in yesterday's blog):  Classifying Solutions of Ionic Compounds.  Make sure you turned this lab in (no conclusion necessary). 

Everyone also turned in the Chemistry Test Review.  ANSWERS ARE FOUND HERE.
