During the abrupt and unplanned transition to remote online learning formats due to the COVID-19 outbreak, educators have had to adopt new teaching methods. For instance, online simulations tailored to specific curriculum topics emerged, allowing students to apply their knowledge creatively, with potentially positive effects on engagement and learning efficacy. Here, we examine the implementation of the “Save the World” simulation, created by Wonderville.org, in a high school Advanced Placement Environmental Science classroom in a remote online learning setting. In this module, students determine the most viable renewable energy generation option for given environments. Based on student and teacher feedback, the simulation effectively delivers educational material and promotes student engagement, demonstrating that online simulations can serve as a viable tool to enhance environmental science education and remote learning.
