The document discusses the Science Action Club program at the California Academy of Sciences, which aims to spark youth interest in science through hands-on, inquiry-based learning. The program provides professional development for afterschool staff and offers a STEM curriculum for students in grades 6-8 linked to citizen science projects. The approach focuses on design challenge learning, giving youth opportunities to brainstorm, problem-solve, and discuss their ideas and designs. Staff are provided with strategies to support and challenge youth through the process, such as asking questions, encouraging wild ideas, and recognizing achievements.
