Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

_____ / _____
_____
Data section includes the provided diagram – completed and taped in. The diagrams are consistent with the holding position. Some form of a data analysis is documented; analysis reveals suitable effort and good reasoning ability. While the analysis does not need to be squeaky clean, it should clearly document the efforts to relate the resonant frequencies to the standing wave patterns.
_____
Conclusion/Discussion explains how the resonant frequencies are related to the standing wave patterns. The discussion is consistent with the data analysis (in Data section); supporting evidence is explicitly referenced. The discussion is complete, thorough, and reveals both effort and understanding.

Score
_____
Included, labeled and organized all parts of the lab report.
_____ / _____
_____
Data section includes provided table; table is complete. Work for calculations is clearly shown and labeled. Data is reasonably accurate.
_____
Conclusion clearly and thoroughly describes the effect (or non-effect) that doubling, tripling and quadrupling the string length has upon the frequency and the speed. Writing is organized, clear and responds to the question. The conclusions are accurate and consistent with the data.
_____
Discussion of Results provides the logical support for the Conclusion; specific trials of data are cited as evidence in support of each statement made in the Conclusion section.
S7.
Music in a Bottle Lab
Score
_____
Included, labeled and organized all parts of the lab report.
_____ / _____
_____
Data section includes a diagram of the set-up; length of air column is accurately indicated on the diagram. Frequency-length data is organized in a table with labeled column headings and units. A plot of the frequency-length plot is provided; the results of the linear regression analysis (slope, y-intercept and regression constant) are reported. Results are reasonable accurate.
_____
Conclusion reports the equation relating frequency to the length; variables in the equation are defined; did not use y and x in place of f and L.
_____
Discussion of Results discusses the meaning of the slope (or constant of proportionality in the equation). Relevant information from class discussions and textbook readings are used in the discussion; Logic and reasoning is evident as an effort is made to relate this constant to other physical quantities. Discussion reveals understanding of closed-end air columns.
