Carr's Chemistry Chronicles

What are we doing in chemistry right now? 

January 29th Feb. 23 - Why do the strongest bonds have the lowest melting points? How can we use the physical properties of solubility, conductivity, or melting point to identify if a compound is ionic, molecular, or metallic? And what do those terms mean anyway? The answers to those questions and more will be answered during our study of chemical bonds. We'll also learn to write the names and formula for ionic & molecular compounds and acids. 

Coursework for this unit:

  1. Naming Compounds and Acids worksheet* (here's the answer key to check your answers WHEN YOU ARE FINISHED!)
  2. What's in the Bottle?(questions 1-7) and notes from class to help you through it
  3. Relative Strength of Chemical Bonds and answer key to check answers WHEN YOU ARE FINISHED!)
  4. Covalent Bonds, Ionic Bonds, & Intermolecular Forces (the slime lab)- no answer key provided for this lab.

Class Notes & Materials
If you are absent, or just need to review notes from class, I post each day's PowerPoint notes as a .pdf file on my documents page. 

All coursework assignments (those tracked on stamp sheets) can also be downloaded via Skyward by clicking on the assignment, and then the paperclip icon.

Online Resources

There are numerous online resources available to supplement our course content. Below are my personal favorites. 

Resource Description
Bozeman Science Paul Anderson is a science teacher from Bozeman, Montana who's pioneered the "flipped classroom" concept. That's where students view lessons online at home, then come to class prepared to apply and discuss those concepts. Go to the video link on his page and check out both his Chemistry and AP Chemistry lessons. 
 Tyler DeWitt  Tyler's style is quite energetic, and students find his problem solving videos especially helpful.
 Crash Course Chemistry  Funny and entertaining videos on everything from the nucleus to stoichiometry.  The BEST online periodic table available. If you've got a question about an element, this is the place to go!
 UC Davis ChemWiki  For those who want to know more! This is a college level online textbook resource, one that I utilize regularly when planning lessons and when a student asks me a particularly good question for which I don't have a good answer. 

Contact Information

Please don't hesitate to contact me if you ever have any questions about assignment, coursework, grades, etc. I will respond as soon as possible.

Mission Statement:
I teach to empower my students with the confidence, knowledge, and skills to meet the learning objectives of this class and the 2012 goals of the National Research Council, which states: 



" the end of 12th grade, all students [will] have some appreciation of the beauty and wonder of science; possess sufficient knowledge of science and engineering to engage in public discussions on related issues; are careful consumers of scientific and technological information related to their everyday lives; are able to continue to learn about science outside school; and have the skills to enter careers of their choice, including (but not limited to) careers in science, engineering, and technology."
