Recommended for students ages 9‑12.

Beast Academy Science 4B is the second in a two-part Level 4 science series. BA Science 4B content is aligned to the Next Generation Science Standards (NGSS) for grade 4, but often goes well beyond what is typically expected of students. Science 4B includes units on the power grid, the ocean, and the brain.

Together with 4A, Level 4 is a complete science curriculum for motivated and curious students.
