06:06 On the left side of the page, you can see a heading called Simulations.
06:12 Under the heading, we have a list of links.

New Sims,


Subject-wise Sims,

By Grade Level,

Teacher Resources and other links.

06:26 Here we can choose the appropriate links as per requirement.
06:30 Let us click on By Grade Level link.
06:34 A new page opens with four links:

Elementary School,

Middle School,

High School and University.

06:44 Again choose the link as per your requirement.

I will click on High School link.

06:51 All simulations that are under High School category are displayed on the new page.
06:59 To view all the available Sims, click on All Sims link.

A new page opens with all the Sims.

07:08 Scroll down the page. Notice that we have Simulations in 3 different formats HTML, Java and Flash.
07:19 They are denoted by icons on the bottom-right corner of the simulation.
07:25 The simulations in HTML format are denoted by HTML5 icon, at the bottom-right corner of the window.
07:34 We can directly open HTML format and flash format simulations by clicking on them.

Click on the play button.

The simulation window opens .

07:48 We can work with the simulation till we are connected to Internet.

Back to the previous page.

07:56 To download the simulation for off-line use, let us select Atomic Interactions PhET simulation.
