This season is sponsored by the Mercer University chapter of The National Council Negro Women (NCNW). Its mission is to lead, advocate for, and empower women of African descent, their families, and communities. It was founded in 1935 by Dr. Mary McLeod Bethune, an influential educator and activist, and for more than fifty years, the iconic Dr. Dorothy Height was president of NCNW.

NCNW seeks to establish a more comprehensive, integrated response to the need for science, technology, engineering, art and mathematics education for communities of color. In recognition of the fact that economic stability and career opportunities are enhanced by familiarity with STEAM, NCNW believes it is important to cooperatively plan for and implement measures that will provide greater awareness of STEAM careers and greater access to the paths to those careers.

Giving Episode 9: Play like A Girl with Dr. Kimberly Clay

Play Like a Girl started as a means to fight poor nutrition and lack of physical activity for girls. But in 2014, ESPN recognized Dr. Clay for the work her organization did through a tennis program. That was when she acknowledged her work as a sports organization. In summer 2019, she announced the program’s expansion to include girls-only STEM clubs and lunch-hour mentoring circles in local schools, industry-led STEM tours or Corporate Field Trips and STEM Saturday makerspace workshops where girls get to ideate, create and test the engineering design process. The demand for programming continues to grow every year, with hundreds of groups across the country partnering with us to bring Play Like a Girl to girls in their communities. Since inception, we have proudly served over 25,000 girls and women across the United States and Canada, as well as in Africa and the Caribbean.
