In partnership with early childhood service providers and elementary school systems, the Children's Museum of the Lowcountry will expand the reach of its programming to share its hands-on, play-based approach to STEM education with targeted children and educators. The museum will create a Power of Play curriculum with lesson plans that reflect best practices and focus on play-based activities to teach STEM concepts tied to grade level and state standards. The museum will train and support 40 teachers and educators from ten Head Start/First Steps early childhood centers and ten Title I elementary schools, and provide them with free Pop Up Tinker Shop (a museum on wheels) outreach visits. The trainings will build teacher confidence, promote best practices for play-based learning, support a community of practice, and enhance young learners' engagement, fascination, and attitude towards STEM. The Power of Play Curriculum will be published as a bound resource and shared with other children's museums and service providers.
