Day 54

(IWB - Day 54 Ions & Isotopes)

Students had the opportunity to take the periodic table quiz.  We discussed what an isotope is and how it helped to determine the average atomic mass of an atom.  Following that discussion, we watched a www.brainpop.com video of Isotopes and took the quiz thereafter.  It only took about a minute for students to complete worksheet 3-15 on isotopes.  We then discussed how ions are created and how that effects their net charge.  We watched a www.brainpop.com video on Ions but DID NOT take that quiz.  We ended class by having students work on worksheet 3-16.  Most students had difficulty with this page, so I went over the first 2-4 samples with them.  The bell rang before most students were done, so we will complete the assignment tomorrow.

No homework was assigned, and the Chapter 3 test will be on November 19th & 20th
