PhET is a great resource that Ive shared a bunch of times for many years. Recently, I was checking out the site when I discovered that its
activity search tool now includes a filter for remote activities. Through this search tool you can locate lesson plans developed for remote direction and learning. You can integrate the remote search filter with any of the other subject, level, and language search filters.
See this brief video to see how it works..

Lots of the PhET simulations are readily available to place into PowerPoint presentations through the use of.
PhETs free PowerPoint Add-in. With the Add-in installed you can browse the readily available simulations and place them into your slides. The simulations work in your slide simply as they do on the PhET site.

In the following video I demonstrate how to include PhETs science and mathematics simulations in your Google Site. Those of you who enjoy the video will also see that the simulations can also be shared by means of a direct Google Classroom combination.
