All VGN's are written by SciHigg (Justin Higgins) include discussion/review portions, have few fill in the blanks, and focus on student analysis. Only the PDF student versions are linked on this website. For educators looking for access, please see the FAQ page.

Only materials that I, Justin Higgins 'SciHigg', have developed privately, on my own equipment and time, are listed here.

If you wish to use these VGNs, you will need to have ownership of the publication.
