What's going on in class 2/11-3/1

IB Chemistry

Some useful polymer videos:
(1) a good one from M2 Polymer Tech (12 min): http://www.youtube.com/watch?v=RMO6srwL2pQ and a pdf version: http://www.m2polymer.com/pdf/Superabsorbent-Polymers-Video.pdf
(2) silly Dr. Cheikhe version- can skip first 3 min (9 min): http://www.youtube.com/watch?v=B_XJ76OQC1w

Friday you will have the 50-minute period to plan and write your hydrogel beads IA.  You may use (and should!) notes and refer to your old IAs.

Hydrogel Bead Information- pamphlet that I showed you in class: http://www.asminternational.org/content/docs/water.pdf
The hydrogel beads are made from Polyacrylamide.  It's the same substance that the "instant snow" is made from.

Chemistry

The student teacher, Lisa Phillips, will be taking over classes sporadically over the next few weeks, but full time in March.  We sent out an introduction letter, but you can also see the letter on the Wikispace page linked below.

Reactions!  You're learning how to observe a reaction and then write a complete, balanced equation.  Big time Chemistry!  The Reaction Types Project is due Tuesday 2/19.  Details:

• Make a power point (or paper slide video)
• with Pictures to represent the 4 main reaction types (combination, decomposition, single replacement, and double replacement)
• Include a sample full, balanced equation of each type- there are tons of examples in your packet
• Make it cute and creative to get 100%

The rubric for the project and an example are posted on the wikispace (link below)
