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 Matter Density Ranking Tasks Directions

Density Ranking Tasks - Directions

Using the Density Ranking Tasks Concept Builder is quite simple. There are three activities in all. Every question in every activity involves the same basic task - to rank three samples of matter according to their density. In each question, information about three samples of matter is provided. The information that is provided is different in each of the activities. Nonetheless, the information is sufficient for making judgements about the relative density of the three samples. The densities can be ranked - greatest, smallest or middlest - by tapping on answer fields. Tapping on an answer field will toggle the answer from smallest to middlest to greatest. Once the desired ranking is displayed for a given sample, quit tapping on that field. Once all samples have been given a unique ranking, a Check Answer button will be displayed. If you are satisfied with your choice of rankings, tap on the Check Answer button. Your answer will be evaluated 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.
