Day 61

For periods 3, 6 & 7, we completed worksheet 3-15 to begin class.  Afterwards, along with the other two classes, we practiced the periodic table quiz.  I instructed students to disregard the four atomic forces (electromagnetic, strong, weak and gravity) at the end of their notes.  That being said, we covered the remaining material in section 3-4 notes, which included ions, electron clouds and energy levels.  I used this link to demonstrate electron arrangement within an atom.  I revealed how the number in the left-hand corner of the element's block on the periodic table identies its electron distribution among the energy levels.  I also discussed how ions were created, which led to today's http://www.brainpop.com/ video on Ions.  Students did not take the quiz following the video.  Instead, students did worksheet 3-20 while I used an IWB flipchart to demonstrate the same page.  We ended class by doing worksheet 3-19 before the bell rang.

No homework was assigned, and the Chapter 3 test will be on Tuesday, December 6th.
