I realize your plate is full as you scramble to create lessons in a fully online world as we all battle the Corona Virus. Phet is a terrific site that was created by the University of Colorado Boulder. It is FREE and does NOT require a log in. They have activities for elementary, middle, high school as well as university. Many times I lauded the interactives offered by SAS Curriculum Pathways. Since they have shut down their site, the activities were added to Phet. I have links to both a math lesson as well as science to give you an idea of what is there. Enjoy and Stay Safe.
