Physics Classroom is making strides to make our site accessible to everyone. 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. The Primary Navigation handles the first 2 levels of site pages. The Secondary (which is not always available) handles the 3rd and 4th level of structure. The Page level navigation allows you to navigate the current page's headings quickly. The Header Navigation contains the Light/Dark Mode toggle, Search, Notifications and account login. The Breadcrumb Navigation contains the breadcrumb of the current page. If the current page has a breadcrumb, you can get to it by skipping to the content and tabbing in reverse (shift plus tab). The Footer Navigation contains links such as Privacy, Contact, about and terms. Some resources contain an Audio Player that can be activated by holding down the T key for 3 seconds, and then using K to pause and resume. 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 this link to contact us.

Know Your Potential - Directions

Using the Know Your Potential Concept Builder is quite simple. When you start up the Concept Builder, you must enter your name tap on the Start button. Your name will be used in all Progress displays; it is never saved in any database. Once you tap on the Start button, you will be taken to the Main Menu. There you willl be presented with the three activities - Color Those Wires!, Which Bulbs Light?, and Volt On It!. Each activity consists of four circuits which you must analyze. You can do these three activities in any order but we recommend that you do them in the order in which they are presented - Color Those Wires! first, followed by Which Bulbs Light?, and finally Volt On It! Once you complete an activity, you will receive a Medal for that activity. The Medal is displayed on the Main Menu screen.
