ExCell in Science supports early science education among underserved preschoolers by creating science lessons, teacher training and assessment tools — and working with educators to ensure long-term success. While science education in pre-school provides a critical foundation for future learning and advancement, the ExCell in Science program — led by Carol Hammer, Professor of Communication Sciences and Disorders — aims to address two key barriers. First, there are very few high-quality and evidence-based science programs designed for preschoolers. Second, preschool teachers typically have not received preparation on how to teach science to young children.

Impacted Community: 1700 preschoolers and 96 teachers in the City of Philadelphia, which has the highest poverty rate of the most populated cities in the United States. Long-term, the study has the potential to inform the education of millions of young learners across the U.S.
