PearDeck has the ability to embed a webpage directly into the presentation. For example, I may be giving a lesson on a historical site. I can have 1/2 the screen show my notes and 1/2 the screen show an embedded website such as Google Earth or maybe an interactive science/math app while teaching a specific science/math concept.

This keeps the learners in one presentation so that they do not have to leave and return. I can also embed a Google Form, Doc, Sheets, etc on 1/2 the page so that my students can interact with these while still in the presentation.

Here is a link to what I'm trying to describe. https://help.peardeck.com/embed-websites-and-activities-in-your-pear-deck
