Spring Break Homework= May 2009 Exams- Paper 1 and Paper 2
What's going on in class? Start of a New Semester!
IB Chemistry
Welcome back! Second semester is going to be tough (of course), but very rewarding (also, of course). You'll get back into some Organic Chemistry, plus you'll be learning about Food Chemistry- additives, packaging, antioxidants, colorings, and Environmental Chemistry- ozone, global warming, waste management, and water purification.
There will be a final exam in early May. I like to give it before students take the real IB exam May 19, so they get the full experience before it counts for potential college-credit.
Chemistry
Please note that the "Chemistry of __" project will be pushed into next semester because we just don't have enough time to complete it without creating homework this week.
This semester is going to be fun! We'll start with a unit on reactions-- yay! Lots of labs! Then, we're on to Stoichiometry (big word, huh?), acids and bases, reaction rates, and finally organic chemistry. We'll have three big labs this semester (1) examining the yield in a magnesium reaction (2) investigating rates of a reaction with acetic acid and (3) ranking diaper absorption.

IB Chemistry:
Use this site to access the class wikispace: mrsbullock.wikispaces.com/IBChemistry
It has most of the general resources, the Equilibrium/Acid-Base unit materials, and a little bit for midterm review. Let me know if there's a file you want that isn't there...
For your research on industrial equilibria, look wherever you can, but here are a few helpful sites hand-picked by me:
The midterm for this class will be an actual IB exam (minus the Organic questions)- paper 2. It's written, cumulative, and of course super hard and super generously curved. We will work through 1 full test (Paper 2) in class. Plus, there are a couple of review tools on my wikispace- a review game that I have used in the past, a study plan template, and a hear/think activity which should help you answer the written questions.
Topics on the midterm:
(1) Quantitative: molar conversions including molarity, percent composition/empirical formula
(2) Atomic Structure: electron configurations (including ions), isotopes, mass spectra, emission spectra
(3) Periodic Table: ionization energy trend, acid/base nature of oxides, reactivity trends
(4) Bonding: Lewis structures, VSEPR shapes
(5) Redox: reactions, electrolysis, voltaic cells
(6) Thermo: Hess's Law, bond enthalpy
(7) Kinetics: factors which affect rates- how and why
(8) Equilibrium: K, LeChatelier's principle (shifting equilibrium)
(9) Acid/Base: strong/weak, Bronsted-Lowry
Chemistry:
We're doing some experiment design/scientific method stuff at the end of the semester.
You have a big report due Wednesday 1/15: # of Atoms in Your Name with Chalk. It will be graded using all categories of the Lab Rubric.
Then, we'll do another shorter one finding the %composition or pennies where you'll get to do some more sophisticated mathematical manipulations. This will be done completely in class.
The midterm exam will be cumulative and multiple choice. You'll get a review guide and some practice in class. But, you should also be studying your old packets and notes.

Have a great holiday and a very happy start to 2014!
What's going on in class? 11/18-12/20
IB Chemistry
Redox Extra-credit (due before the Holiday break on December 20):Research 1 specific type of battery (for example D-cells, car batteries, fuel cells, solar panels, AAA, Lithium battery) and make either a mini-poster or pamphlet explaining the CHEMISTRY of how it works.
In class right now it's.... THERMOCHEMISTRY! That means heat changes in chemical reactions. You'll be learning about how and why reactions change heat, plus how to calculate the heat change in a process using calorimetry, Hess's Law and Bond energies.
You'll also be doing your big IA: Investigate 1 factor which affects that results of a calorimetry experiment. You can use either the burn-under-water technique or the reaction-in-a-cup technique to find the affect of one factor on the calculated heat change. This is a FULL IA, will all 3 sections, due December 19. Fun!
Chemistry
Bond Test Thursday 12/12! You've been learning about ions, names and formulas for ionic compounds, covalent bonding, Lewis Dot structures, VSEPR shapes, and intermolecular bond strengths. Whew! But, the ionic names and formulas are by far the most important part. That is the section which will carry through into other units and is the section which carries the most weight on the test.
Next up, you finally get to learn about.... THE MOLE!
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:
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)

Lewis Dot Tutorial that I mentioned in classWe are wrapping up our last review unit- Atomic Structure, Periodicity, and Bonding. You'll have a bonding test Thursday in class. Plus, they will have a homework calendar due that day. Plus, your silver lab (Conclusion and Evaluation only) is due Wednesday
Next up: Redox.
Starting next week, review will be over and you'll be learning all new stuff. Yay! The pace will slow a little bit, but the content will get more difficult. Redox will last about 3 weeks... which will take use all the way to Thanksgviing break.
Chemistry
This week we will focus on the Periodic Table and learn about the patterns on the table for reactivity, melting point, atomic size, electronegativity (whoa! big word...), and ionization energy. Part of this section will be a project- "The Periodic Table of..." where you will make a table of something that interests you. It's a lot of fun, so stay tuned for details.
This unit will wrap up Nov 6, just before
parent conferences.
What's going on in class 10/1-10/13
IB Chemistry
We have just finished a big Stoichiometry review and learning about how to write an IA (Internal Assessment). This week, it's time to do a REAL IA! Students are using titration to find the %CaCO3 in an eggshell. I encourage you to all use the IA template (all files are on a wikispace, see link down below).
Next up is Atomic Structure, the Periodic Table, and Bonding. This unit includes a review of atoms, electron configurations, periodic trends, VSEPR, Lewis structures, polarity... from regular Chem + you'll learn about mass spectrometers, empirical formulas, and how to write concise answers to IB questions. Cool stuff!
October 11 is the Group 4 Project: A project where students from all disciplines of IB Sciences come together to create experiments and interpret data together. You will be conducting an experiment out at Dillon Falls along with a group of other students and thinking from a Chemist-perspective. At the end, you will produce a poster which needs to be up in S-Hall by Tuesday 10/15. You will be graded on your poster, but also your "Personal Skills" as required by IB.
Chemistry
Right now, we're wrapping up a unit on designing experiments-- Including an experiment on which materials have the fastest cooling rates. Friday we will be making videos on how to find/write about sources of error. Get creative.
Next up= States of Matter and Gas Laws. You'll be reviewing kinetic theory, but also learning how to explain gas behavior using math. How much does a weather balloon's volume change when it's way up in the atmosphere? How does a potato gun work? How does dry ice turn to a gas?

Who am I?
Hi there! I just want to take a minute to introduce myself and give you a little of my background.
My name is Casie Bullock. I grew up in Texas, went to high school in Chicago. Then, I went to Michigan State University where I played soccer and majored in Chemistry in the Honors College. I graduated, goofed off for a while, and then landed in Tahoe where I worked for AmeriCorps- working with the teen parent and AVID programs at South Tahoe High. After that, I worked for 3+ years at a biotech company in the Bay Area called Inhale. We made (or tried to) injection drugs into powders that could be inhaled through the mouth. Insulin was supposed to be our big product. That didn't work out, and I had always wanted to teach anyway, so I got a teaching credential at San Jose State and started teaching in 2000. I spent 3 years at Branham High in San Jose. Then, I moved to New Zealand for 3 years and just ended up teaching by accident! (Yep- there's a story there) We moved back to the Bay Area (what a shock after living in a town of 3000), couldn't deal with it, and escaped to Bend. After a year of tutoring, subbing, and baking, I landed at Bend High (Yeah!). The 2012-2013 school year will be my 11th year teaching and my 6th at BSHS.
I LOVE my job. There are so many things that make it wonderful, and I'm excited for the school year. My goal is to create a classroom where students feel safe, have fun, and are challenged to truly think, to question everything and search for their own answers, and to be scientists.
But, I also love my family. I have a husband named Grant and 2 little boys named Cal and Ian. In between, I am usually outside- playing soccer, running, hiking, skiing... whatever gets me out.

We're studying Food Chemistry right now- hydrogenating fats, antioxidants, preservatives, artificial and natural colors, and genetically modified foods. By the end of the unit, you'll know how haggis is made, what the issues are with GMOs, and about some scary food additives. You'll also be able to argue both for and against food preservation and describe some of the extreme food waste in North America.
Your final IA is due Friday 3/8. If you're really wanting to improve your IB score, you can choose to do the optional one highlighted on the wikispace (see link below).
There is no test for this unit... just little quizzes: Groups/Fats, Shelf Life, and Terms.
Chemistry
Stoichiometry! We're learning about how to convert amounts of 1 substance into amounts of another by using the balanced equation. For example: If you have 0.9g of Mg and react it in air, what mass of MgO will you make? Then, we'll be doing the same type of calculations but given two amounts. For example: If you have 0.9g of Mg and 10L of O2, what mass of MgO will you make? For this second one, you need to first figure out which reactant limits the amount of product/which will get used up.
Extra Credit WS on the wikispace (see link below): Stoichiometry 3
Plus, there are a few random worksheets available in the classroom, so you can take one and do it for an extra stamp on your packet.

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.

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%
