In BioDive, students are marine biologists who travel to international dive locations in VR. They will study the impact of abiotic factors on biotic factors across diverse marine ecosystems and then document their learning in their digital science journals in the companion website. As students move through the experience, they go between their own personal digital science journal (https://biodive.killersnails.com/) and expeditions in the field, including the Eastern Atlantic, Eastern Pacific, and Indo-Pacific Oceans. They make observations, collect data, collaborate with fellow scientists, and synthesize their knowledge to write formal hypotheses about the impact of variables on changes to different ocean ecosystems. Players must have access to the digital science journal to view more than the first scene. BioDive was developed by a team of science teachers and scientists to model the process of scientific inquiry and discovery. Students use their devices to make observations and use their laptops to manipulate data and synthesize observations to demonstrate learning. This game was created by an award-winning team co-founded by a practicing marine biochemist. BioDive was developed with support from the National Science Foundation!
