Both in-school and out-of-school opportunities play an important role in students' STEM learning and engagement. Informal STEM learning opportunities reflect an important community resource. Community-based programs, museums, science centers, zoos, aquariums, and environmental centers can inspire interest in STEM, build knowledge and deepen learning, provide real-world connections, and enable students to see themselves as science learners. These experiences can also provide students underrepresented in STEM with exciting experiences in these areas and opportunities to connect with role models. Businesses also play a key role, supporting schools and community-based programs and providing internships and opportunities for exposure to STEM careers.
