120 Video scripting. To minimize cognitive load and provide easy video navigation, each video script was subdivided in discrete "scenes" (see Supporting Information Video recording. To create a video process that would be as adaptable by others as possible, all videos were recorded on mobile devices and edited using free software. The QR videos were filmed in the laboratory spaces that students would be completing the experiments in; special attention was paid to the appropriate PPE and chemicals/equipment that students would need to follow along with the video and provided experimental handout. While filming, the techniques were performed slowly to ensure students could easily watch and replicate. No voice-overs were recorded, as students are expected to watch the QR videos during their laboratory section; we wanted to prevent video dialogue from distracting other non-participating students. Instead, we provided captions on the lower half of the video frame for students to follow along with visually.
