If your kid has to do science homework on a screen, this is about as good as it gets. It moves past the 'watch a movie and take a quiz' model of the original BrainPOP and actually asks middle schoolers to do the heavy lifting of scientific inquiry.
It’s not a 'game' they’ll play for fun on a Saturday, but it is a high-quality supplemental tool that respects their intelligence. The focus on the Claim-Evidence-Reasoning (CER) framework is the standout feature here—it's basically a BS-detector for life disguised as a science lesson.
