I know many teachers prefer to participate in the two minute silence alongside their students.
The PowerPoint will play automatically in ‘show’ mode - just advance the first slide , a cover image - and follow the instructions to begin. During the two minutes, a series of photos will fade in and out and a clock will show the two minutes passing by. The photos stop, when the two minutes are up.
I have attached a video as a preview, so you can view before downloading, to check if the show is suitable.
