Yes, you can! A very nice feature to include storytelling in your trip, e.g. by staff members, you, or stakeholders from the area! So while creating a field trip think about this. You can either directly upload files using the “Add Media” button, or link to an external player (keeping in mind the data consumption for the students, roughly 35 MB/1 min of video streaming).
PeekMakes excursions fun!
