The National Center for Science Education (NCSE) is a not-for-profit organization that defends and promotes the teaching of science in public schools. We provide information, resources, and support on areas of science that are often attacked on social or political grounds—such as climate change and evolution. Our goal is for all science teachers to have the skill and expertise needed to cover these topics accurately and effectively, even in places where community acceptance is low, misconceptions are widespread, and teachers’ fear of conflict in the classroom is reasonable. The Science Booster Clubs (SBC) support NCSE’s mission by addressing community-level discomfort about such socially controversial topics through hands-on, fun and accessible activities. Funding for the SBCs comes from NCSE, which in turn is supported by individual donors and charitable foundations. Every activity is made available to both the volunteers and the public free-of-charge. SBC volunteers are local members of a community who present our activities in farmer’s markets, fairs and libraries. Each SBC is rooted in its community, driven by local volunteers, and adaptable to the needs of the particular region. We are specifically interested in reaching scientifically underserved communities. Currently, there are SBCs in 14 states, with plans to gradually expand into more locations in 2018 and 2019 with the eventual goal of building a comprehensive national program.
