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

Physics Interactives: Who Can See Who?
The Physics Interactives is our simulation section.This section provides a playful way to learn, Alter a variable, experiment with a system, and interact with the simulation in order to find out how nature works. While our Who Can See Who? activity is unrelated to this Six-Foot Person Problem, it does provide another useful application of ray diagramming.
Minds On Physics, Reflection and Mirrors module, Mission RM3
A Minds On Physics mission is an interactive questioning module that will make you read carefully, think deeply, and know your concepts. None of this is popular. All of it works. Give Mission RM3 a try in order to sharpen your understanding of ray tracing.
Curriculum Corner, Reflection and Mirrors
Our Curriculum Corner includes in excess of 200 Think Sheets on discrete topics. Each Think Sheet takes a developmental approach to a topic. The one on Ray Diagrams includes some content related to this 6-foot person problem. Blend it with a MOP mission or our simulation (below) and you will have a great lesson.
Physics Interactives: Who Can See Who? Simulation
There are five students sitting in front of the mirror. Who can each student see? This interactive exercise provides students immediate feedback and guidance. It's a "no-fail" activity; every student will eventually succeed.
Concept Builder: Who Can See Who?
Students love Concept Builders. They provide a large bank of questions of varying difficulty, an intelligent question-delivery system, and immediate feedback on student answers. They can be used in class or (with our Task Tracker system) out of class as quick formative assessments. While this one is unrelated to the six-foot person problem, it still goes a long way towards assessing student understanding of other ray diagram applications.
Minds On Physics, Reflection and Mirrors Module, Mission RM3
Minds On Physics has always been a tool that trains students to read closely, think deeply, and reason conceptually. This mission on Plane Mirror Ray Tracing will do all that and more. Give it a try.
Teacher Toolkits: Plane Mirrors
We love our Teacher Toolkits. We hope you do as well. They include a collection of links to vetted resources throughout the web that are standards-based and multi-media driven.
