    This is an excel worksheet (the newer .xlsx version which will downgrade without trouble using MS converter) which follows the principals outlined in the brochure above. The workbook contains 3 sheets with instructions that allow the user to 1) Plot data without a fit to see the form of the relationship, 2) Plot data and fit to a straight line (useful once the students understand how to 'linearize' the data according to a model function) and 3) the same as 2 but allows students to enter error bars (intended for my AP students after we have covered error analysis). Both graphs in 2) & 3) have residual plots so the students can see the scatter from the model fit. With a little abstraction I suspect that this could be used to describe how to set up a chart in Open Office as well. {HOWTO Excel Graphing.pdf}

    15. How to grade lab reports more quickly.
    This technique is an overall suggestion on how to add extended comments to a lab report without having to write the same thing again and again. Instructions are included on how to customize the technique for your own standards and comments.

    Explanation to delve a level deeper than what one might expect of AP physics C students, and help myself and other teachers understand why and how this material is presented the way it is (without fictitious forces) at the introductory physics level.
