Whether you are a parent looking for a fun day out, a student passionate about discovery, or simply someone who loves learning, this event has something special for you.

What Is the Bay Area Science Festival?

The Bay Area Science Festival is Northern California’s largest free science celebration. The Science & Health Education Partnership (SEP) at the University of California, San Francisco organizes it. UCSF works hand in hand with Bay Area universities, museums, cultural institutions, research labs, libraries, after-school groups, corporations, and government agencies to make the event possible.

The festival first launched more than a decade ago with a simple mission: bring science to life for everyone. Over the years, it has grown into a community-wide celebration that draws thousands of visitors each year. Additionally, it serves as a powerful reminder that science is not just for experts. It belongs to all of us.

Over 125 Hands-On Experiences Await

One of the most exciting parts of this festival is the sheer variety of activities on offer. Visitors can expect more than 125 hands-on experiences spread across the grounds. These are not passive displays. They are interactive stations where you can touch, try, and discover for yourself.

From biology to robotics, chemistry to environmental science, every corner of the festival offers something new. You can conduct simple experiments, test your problem-solving skills, and get up close with technology that might feel futuristic at first glance. However, by the end of the day, it will all feel completely real and reachable.

Live Science Demonstrations

Live demonstrations are always a crowd favourite at the festival. Scientists and science educators take to open spaces and stages to show off some of the most jaw-dropping experiments you will ever see. These demos are designed to surprise and delight people of all ages.

You might watch a chemical reaction produce a burst of colour, or see a physics experiment that seems to defy common sense. Each demonstration comes with a clear explanation, so you understand not just what is happening, but why. Therefore, you leave not just amazed, but genuinely informed.

Behind-the-Scenes Lab Tours

For those who want to go deeper, behind-the-scenes lab tours offer a rare opportunity. UCSF is one of the world’s leading research universities, and the festival opens some of its labs to the public for this special occasion.

You can see real laboratory equipment, meet working scientists, and learn about the kinds of research happening right now at UCSF. These tours are typically led by scientists themselves, which makes the experience even more meaningful. It is one thing to read about how science works in a textbook. It is quite another to see it unfolding in a real lab.

Science Talks and Presentations

The festival also features a line-up of science talks. These sessions bring together researchers, educators, and STEM professionals to share their knowledge in an accessible way. Topics span a wide range, from health and medicine to space and climate science.

The talks are designed to be engaging, not lectures. Speakers know how to connect with general audiences and make complex ideas easy to grasp. Additionally, many speakers are passionate about mentorship and will take time after their presentations to chat with aspiring scientists, especially young attendees.

Exhibits from Universities, Museums, and Research Labs

The exhibit area is the beating heart of the festival. Dozens of organisations set up interactive booths where you can engage directly with their work. Bay Area universities bring their latest research. Museums bring their most engaging educational tools. Research labs share discoveries that are pushing the boundaries of what we know.

Here is a sample of what you might encounter across the exhibit floor:

Exhibit Theme	What to Expect
Biomedical Science	DNA models, microscopes, and health innovations
Environmental Science	Climate data, wildlife conservation, and sustainability
Space and Astronomy	Planet models, telescope views, and space exploration
Robotics and Engineering	Build challenges, robot demos, and coding activities
Mathematics and Logic	Puzzles, pattern games, and visual math concepts
Physics and Chemistry	Experiments with light, sound, and materials

Each booth is staffed by enthusiastic volunteers and professionals who love talking about what they do. Therefore, do not be shy about asking questions. That curiosity is exactly what the festival aims to encourage.

Family Activities and Kids’ Zones

The festival has always been deeply family-friendly, and 2026 is no exception. Children are at the heart of everything. There are activities designed for toddlers, primary school children, and teenagers alike. No matter the age, there is something engaging waiting.

Young children can enjoy simple sensory science activities and colourful experiments. Older kids can dive into more challenging engineering tasks and science games. Teenagers, meanwhile, will find plenty of inspiration from STEM professionals who share how they got started in their careers. These personal stories are often the most memorable parts of the day for young visitors.

STEM Role Models and Career Inspiration

One of the most valuable aspects of the festival is its focus on STEM role models. Across the grounds, you will meet scientists, engineers, doctors, researchers, and technologists from a wide range of backgrounds. Many of them are there specifically to inspire the next generation.

Seeing a scientist who looks like you, grew up in a similar neighbourhood, or faced similar challenges can be transformative for a young person. The festival understands this deeply. However, it also knows that role models matter for adults too. Seeing what people achieve in STEM fields can reignite a passion for learning at any stage of life.

Film Screenings

Alongside the live activities, the festival will feature science film screenings. These short films cover a broad range of topics in engaging, visual formats. They are a great way to wind down between hands-on activities while still absorbing new ideas.

The screenings cover topics that tie into the day’s broader themes. Some highlight scientific discoveries. Others focus on the human stories behind breakthrough research. Together, they add a thoughtful, reflective dimension to what is otherwise a very active and energetic day.

Accessibility and Inclusivity

UCSF is committed to making the festival welcoming for all visitors. The event is designed with accessibility in mind. If you or someone in your group needs a reasonable accommodation because of a disability, you are encouraged to reach out to the festival team in advance at info@bayareasciencefestival.org.

The organisers take inclusivity seriously. This festival is for everyone, and the team works hard to ensure no one feels left out. Families of all backgrounds, languages, and abilities are warmly welcomed.
