Chemistry – Beyond Core

Introduction

Work continues on finishing the materials for the remainder of the course. What follows are beta-versions of units which address other key concepts that modelers feel are appropriate for a 1st year course. There are detailed teacher notes for units 10 – 14, but some resources (worksheets, quizzes, tests) are incomplete.

Because many chemistry teachers report that they need to address the internal workings of the atom in the first semester (due to district tests), we suggest that they could do units 10 & 11 right after Unit 6. They could then return to Units 7 – 9.

If you have any questions, comments or concerns, you should direct them to Larry Dukerich.

Outline

  1. Models of the Atom:  From an examination of the radiation emitted by hot metals and atomic gases we conclude that atoms must have internal structure not explained by Thomson’s model.
  2. Periodic Table and Bonding: We extend the Bohr model to many-electron atoms, using it to provide a structural explanation for the organization of the Periodic Table, and to examine models of covalent bonding in compounds.

At this point, two paths are provided. Those who wish to delve more deeply into the difference between energy and temperature might choose to use Unit 12A. Teachers whose course precedes a capstone biology course, or who wish to investigate some basic biochemistry would choose Unit 12B.

  • 12A – Temperature and Thermal Energy: We know that when Ech of the system changes, the Eth also changes, eventually resulting in a transfer of energy between the system and the surroundings. We adopt a “kinetic” view of temperature to account for the direction of energy flow. There are additional materials -Entropy for AP Chem – suitable for an honors or AP course.
  • 12B – Intermolecular Attractions and Biological Macromolecules: In this unit we suggest a model to account for attractions between molecules and the effect on physical properties. Then we move to an investigation of organic molecules important to life.
  1. Equilibrium: We employ a “kinetic” view of particles moving back and forth across an interface to model a variety of processes (both physical and chemical) as they approach and reach the state of equilibrium.
  2. Acids and Bases: We extend what we’ve learned about equilibrium to the Bronsted-Lowry model of acids and bases, characteristics of strong and weak acids and neutralization reactions.

    I’m very excited about using the resources on this website. I only wish I found them a year ago when I started teaching. It would have saved me many sleepless nights. The scripted lessons are just what any new teacher needs! :)

    We’re pleased that you find them useful. Spread the word.

    i just downloaded the zip files for chapters 1,11,12,13 and 14
    I then extracted the files from the zip files. almost all of the word files open with just garbage characters.
    the school had installed the newest version of word on our laptops, would that matter?

    any help would be appreciated

      An unfortunate consequence of using Windows to unzip an archive zipped on a Mac is that a whole set of extra files appears at the top of the folder. These all have filenames beginning with “._” as in ._filename.doc” You will note that these are all tiny files (1-2 KB). The real files, fully functional appear below. Simply ignore these extra files which are an artifact of the way Windows unzips the archives.

    thank you for clarifying that. the format really confused me. looks as though the download worked!

    Anyone have any solutions to the assignments for these units?
