What's going on in class 10/31- 11/7

IB Chemistry:

REDOX!  Yay!  New unit starts Monday and it's called Redox.
You will be learning about electron movement in reactions and how we can harness those electrons to create batteries, plate metal, or recover reactive metals from nature.

The next IA is November 22- a design IA revolving around Voltaic cells.  You will do the entire thing in class that day.  I will give you some tips to prepare, but 50-minutes is enough time to do a stellar job.

Thanksgiving: (1) Review Crossword (2) Optional Redox extra credit assignment discussed in class

Chemistry:

We're wrapping up a unit on the Periodic Table.  Is there anything more important in Chemistry?  By now, you know a lot about atom structures, isotopes, electron configurations, and how to read the periodic table.  The final phase is periodic trends.  The table is full of them!  You'll learn what the trends are for reactivity, size, ionization energy, electronegativity, and melting point.  But, most importantly, you'll be able to explain WHY the trends are what they are.

The test for this unit has 2 parts: essay on Nov 5 and multiple choice on Nov 7.

Next up = Bonding: naming and writing formulas for molecules

Periodic Table of... project details:  DUE Friday 11/8

Create a periodic table of something, ANYTHING other than elements.  Your table must have at least 20 items.  They must be arranged so that there are sensible patterns across (left to right) and down (top to bottom) your table.  It need not be in the same shape as the original periodic table.

Here are a couple of online examples to get your creative juices flowing:

Candy: http://www.drchinese.com/periodic_table_of_candy.html

Instruments: http://pubs.acs.org/supplements/chemchronicles2/pdf/poster.pdf

Dessert: http://www.eblong.com/zarf/periodic/closeup.html

Tools: http://blog.makezine.com/archive/2007/01/periodic_table_2.html

Your table can have pictures from magazines, from the internet, drawings, or just words.  It should be on poster board (or large paper) for display in the classroom.  On the back of your poster, write a short description of the patterns in your table.

To get an

A+ = The best in the whole room! 20+ items, creative, lots of work put into the trends and project overall

A= The minimum is done with extra creativity, more than 20 items and/or really effective/clear trends

B = Minimum done, 20 items with 2 trends, easy to understand or explained clearly

C = Less than 20 or trends in only 1 direction or really unclear trends (missing explanation)
