Program Profiles

How do successful afterschool STEM programs do it?

These innovative afterschool programs offer impactful STEM programming to diverse populations. Read on to hear their advice for success and to learn about their program structure, evaluation results and partnership models.

Science Action Club

National, United States

Launched in 2011 by the California Academy of Sciences, Science Action Club (SAC) is a nationwide out-of-school time (OST) program for middle school youth that aims to transform environmental learning at scale. Through games, projects, and hands-on activities, youth in SAC investigate nature, document their discoveries, and contribute to global citizen science research. OST staff receive in-depth training on Science Action Club kits, activity guidebooks, and STEM teaching techniques for the informal learning environment. Within the Bay Area region, the SAC program serves as a foundation for the Bay Area STEM Ecosystem, a cross-sector initiative designed to address issues of equity and access to high quality STEM learning opportunities.

Population Served

Over 42,000 youth and educators in more than 200 cities and towns have participated in Science Action Club since 2011. The growing SAC network includes 600-800 clubs each year and served more than 17,000 students in the 2017-2018 school year. Science Action Club is designed for youth in middle school (grades 5-8) and over 70% of participants are students of color.

Program Features

SAC features three environmental science units that use citizen science to spark wonder and curiosity about the natural world. SAC activities provide opportunities for youth to participate in STEM learning that is authentic, interesting, and meaningful to their own lives. SAC’s citizen science projects have global reach, established longevity, and take students outdoors to explore their local environment. For example, Cloud Quest connects to GLOBE Observer, a project by NASA in which youth observe the sky to help scientists understand the connection between clouds and climate change; Bird Scouts connects to eBird from the Cornell Lab of Ornithology; and Bug Safari leverages Academy research on arthropods, using iNaturalist.

Program Structure

Each SAC curriculum unit includes 12 hands-on activities and citizen science investigations designed for 60- to 90-minute club sessions led by OST educators, as well as bonus media and resources for extended learning.

Professional Development

Each Science Action Club kit includes an activity guide, science tools and supplies for 20 youth, and an interactive, self-paced, online training for program staff. Educators are required to complete the professional development course and have the option to attend an in-person training workshop, led by a certified SAC trainer. SAC has partnered with statewide and national afterschool organizations and leveraged the train-the-trainer model to reach widespread geographic audiences. Both the online and in-person trainings provide detailed guidance and support for all 12 SAC activities, as well as background information on scientific content, how to do citizen science, and best practices for teaching STEM in an informal learning environment. The training materials are designed by SAC staff at the California Academy of Sciences and include videos and articles from colleagues in the field.


SAC works with the evaluation firm Public Profit to assess programmatic impact on participating youth, activity leaders, and trainers. Outcome data is collected through pre- and post-session surveys, site visits, interviews, and focus groups. In addition to developing original assessment strategies, SAC employs validated evaluation tools. Through these methods SAC gathers data on youth and staff interest in STEM, engagement in STEM, and the degree to which they value STEM learning.


The Science Action Club program is generously supported by the Pisces Foundation, the S.D. Bechtel Jr. Foundation, the Simons Foundation, the Asian Pacific Fund, Genentech, Inc., the Hearst Endowed Fund for Science Education, and Jacques M. Littlefield Foundation.

Advice for Success

Laura Herszenhorn, Senior Manager of Science Action Club

Katie Levedahl, Director of Informal Learning

Q1 | What’s been most crucial for The Science Action Club's success?

The following have been most crucial in our success:

  1. Identifying key partners at the local, statewide and national levels.
  2. Leveraging the train-the-trainer model to reach widespread geographic audiences.
  3. Identifying and addressing what afterschool programs want and need.
  4. Designing experiences that put youth in the center of the experience. Find out what they want!
Q2 | What were some of the challenges the program faced in its early stages?

In the early stages, the SAC team spent time building relationships and learning about the needs of our afterschool partners. We found that in order for our program to be successful it had to be designed with flexibility to accommodate high turnover and limited resources of afterschool partners. We also needed to focus on professional development for delivering STEM programming, specifically supporting afterschool staff in building the skills and confidence to delivering informal STEM experiences.

As the program continues to scale, we have relied on a nimble and creative team to help us grow quickly to meet increasing demand for the program, which includes modifying the SAC training to include an online component. Gathering accurate and abundant evaluation data continues to be a challenge.

Q3 | For afterschool programs new to offering STEM, what’s your advice?

When designing a STEM program, remember to focus on what your institution does best, and leverage partnerships to support the rest. Science-rich institutions such as museums and science centers often offer STEM content and programming that can meet the needs of afterschool. Do some research to find out what exists in your area.

Q4 | Let’s talk partnerships! How do you develop and maintain them?

We co-wrote an article in Dimensions magazine with other science centers, describing eight helpful strategies on maintaining science center-afterschool partnerships. Read it here:

Q5 | How does Science Action Club support students traditionally underrepresented in STEM?

The SAC program is designed to be accessible for all youth, regardless of background or ethnicity. The curriculum and program design is flexible to meet the needs of afterschool providers who are trained on ways to adapt the learning experience for the needs of their youth. Recognizing the need for “girl-friendly” STEM experiences, SAC also partners with the National Girls Collaborative Project (NGCP) to ensure the program experiences are accessible for all genders. The SAC program is currently running in 12 states through the NGCP network.
