Sample Activity for POGIL™ - Life Cycles of Stars

Most people love to gaze at stars in the night sky. In early childhood when we learn songs like “Twinkle, Twinkle Little Star,” we begin to wonder what they are. Just as people pass through recognizable stages of life from birth to death, so do stars! We experience stars as unchangeable bright specks of light. Despite our personal experience, stars actually change over time – but on a time scale so huge that our lives are just a tiny moment compared to a star’s life. In this activity we will explore the ways stars change over their lives.
