Hi Hannah, not to blur the edges of FOSIL but with Geography projects, have you ever used mystery hangouts as a research tool? It increases engagement and adds collaboration outside school via Google Hangouts. I wrote a blog about some of the tools we use to help students connect it includes a little about hangout too https://www.elizabethahutchinson.com/post/4-online-tools-used-to-engage-teachers-in-collaboration-and-information-literacy. I hope this is useful and if you want to know more just ask. Elizabeth
