With our newest product BrainPOP Science, middle schoolers are inspired to take the lead with their own learning through the exploration of real-world scientific phenomena.

Eye-opening investigations and engineering projects for middle school science classrooms

Inquiry-driven investigations

Relatable guiding questions kick off each investigation with a built-in Claim-Evidence-Reasoning (CER) writing process. Middle schoolers are guided to make observations, practice science skills, and back up their claims.

Real-world engineering projects

With the design process at the heart of every BrainPOP Science engineering project, middle schoolers are challenged with solving problems they might encounter in their daily lives with hands-on prototyping and iterating.
