The San Diego Festival of Science and Engineering EXPO DAY is the largest event of its kind in Southern California. It’s a collective effort between industry, business leaders, government, community organizations, public outreach centers, academia, schools and school districts, and parents. The Festival began 16 years ago primarily science and engineering-focused, with a goal to provide experiential activities in these fields to diverse populations. The overwhelming success of the formative years of the Festival proved to be a catalyst for what the Festival would swiftly evolve into – a comprehensive San Diego County community event that celebrates the diverse cultures, communities and populace of San Diego, and works to inspire the curious young minds of our region to become tomorrow’s STEAM leaders. The San Diego Festival of Science and Engineering Week is ever-evolving and continually responding and meeting the desires and needs of the community. The Festival is the flagship event of Generation STEAM, a 501c3 nonprofit affiliate of Biocom California.
