Most recent site updates

The changes below have been made since 10/27/15, when I started keeping this record. Most recently updated 4-13-16.


  • If a file has “been converted to standard format”, this means that is has been converted from either .doc or .pdf format to .odt (an open source document format).
  • If a file has been “edited”, it has been changed in some non-trivial way.
  • If a file is “no longer read-only”, it is now possible to edit the file as any other document.
  • All files mentioned here now adhere to the (CC BY NC-SA 4.0) Attribution-NonCommerical-ShareAlike 4.0 International Creative Commons License.
  • Sometimes I forget to add stuff, so if you see something new and it’s not mentioned here, don’t be too shocked.

13 April 2016

I’ve actually done a ton of updates in the past month and forgot to include them here. Basically, these have included updating worksheets which were previously in outdated .doc, .docx, and .pdf formats to .odt and adding a bunch of new worksheets on basic topics. There are also some new student handouts, so check ’em out.

Today, I updated some acid/base stuff.

3 March 2016:

I just spent the whole day making the following 11 periodic tables. Because it took so long, I put them all in the public domain to ensure that nobody will ever need to type out a periodic table again.

For those of you who are concerned about copyright issues, scientific data (such as data on the periodic table) is not copyrightable.  I have, however, cited the sources to the best of my ability to figure out where the data originated, because that’s the right thing to do. The actual formatting of periodic tables is copyrightable, but as the originator of this formatting I can put it into the public domain so anybody can use it for anything. This is what I have chosen to do.

2 March 2016:

  • Graphing Practice Worksheet completely rewritten (i.e. new question, teacher answers and background information, correct formatting).

29 February 2016:

  • Each of the changes for today are located HERE.
  • Molarity practice problems worksheet was split into two different molarity sheets. Additionally, each has been completely rewritten and reformatted.  There was nothing really wrong with having a long molarity sheet, but it was pretty tedious to work out all those problems so I decided to just break it up.
  • Dilutions worksheet put in standard format and small edits made.
  • Concentration practice problems worksheet put in standard format and small edits made.

26 February 2016:

  • The chemistry-specific autocorrect file for LibreOffice has been updated and a new download is available here.
  • Updated, edited, converted into standard format, and generally made the Balancing Equations Race activity way more awesome.  Located on this page.

24 February 2016:

  • Updated and edited ten percent yield and stoichiometry worksheets on this worksheet page.  Also converted them into standard format.
