This book explores what happens in your brain when you feel happy, the chemicals your brain produces, and ways to be happy more often. STEM concepts cover aspects of psychology and neurology in simple terms, while social and emotional learning (SEL) concepts support the growth mindset. Grow with Goals and Try This! activities further reinforce the content. Vibrant, full-color photos and carefully leveled text engage young readers as they learn more about the science behind happiness. This title also includes a diagram of the brain, sidebars, a table of contents, a glossary, an index, and tips for educators and caregivers. Your Brain When You're Happy is part of Jump!'s Brainpower series.
