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.

Home Concept Builders Fundamentals: Units and Measurements Significant Digits Directions

Significant Digits - Directions

Using the Significant Digits and Measurement Concept Builder is quite simple. There are three different activities, each of which has a different emphasis. In the first activity - What's Significant? - you are presented with a numerical value and asked to determine the number of significant digits in the value. You can select your answer by tapping on the answer field. Each time you tap, the answer option is changed. After you have passed through all answer options, you can cycle back through from the beginning. When you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated, feedback will be given, and your Progress Report will be updated.

In the second activity - Measurement - a graphic of a measuring tool is shown. You must use the measurement tool to make a measurement to the proper number of significant digits and then to identify the measurement from among the set of six answer options. Select your answer by tapping on the answer option (or the radio button to the left of the preferred option). Once you select an answer, the Check Answer button appears. If you wish to change your option, then you can tap a second time on the selected option or simply tap on another option (or the radio button to the left of that option). When you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated, feedback will be given, and your Progress Report will be updated.

In the third activity - Math Operations - you will be given information about two measurements being made. You will have to use the measurements to calculate a third value. As you do your calculations, you will have to express your answer to the proper number of significant digits. Identify your calculated answer from among the set of six answer options. Select your answer by tapping on the answer option (or the radio button to the left of the preferred option). Once you select an answer, the Check Answer button appears. If you wish to change your option, then you can tap a second time on the selected option or simply tap on another option (or the radio button to the left of that option). When you are satisfied with your answer, tap on the Check Answer button. Your answer will be evaluated, feedback will be given, and your Progress Report will be updated.

Your goal is to earn "Stars" and to complete one or more activities. Stars are earned when you show success on a particular question. Once you show success on all the questions for a particular activity, you will earn the trophy for that activity.
