PhET is a fantastic resource that Ive shared a lot of times for many years. Just recently, I was checking out the website when I noticed that its
activity search tool now includes a filter for remote activities. Through this search tool you can locate lesson plans designed for remote direction and knowing. You can integrate the remote search filter with any of the other topic, level, and language search filters.
View this brief video to see how it works..

Lots of the PhET simulations are offered to place into PowerPoint discussions through using.
PhETs complimentary PowerPoint Add-in. With the Add-in installed you can search the offered simulations and place them into your slides. The simulations work in your slide simply as they do on the PhET website.

In the following video I show how to include PhETs science and math simulations in your Google Site. Those of you who watch the video will also discover that the simulations can also be shared via a direct Google Classroom integration.
