Ten Strands

Ten Strands · FY25–26 annual impact report

Local ripples,
lasting waves.

Follow one California river from the first snowmelt to the sea — and see what your support set in motion along the way.

Begin at the headwaters
“I’ve come to realize how crucial it is to equip students with the knowledge and skills to understand and protect the world around them.”
John Atwater · supporter, with Diana Nelson · more supporter voices

Every current begins as rain.

Climate change shapes the world our students are inheriting, and education gives them practical ways to understand and respond to it. When a student learns to read a watershed, question a food system, or speak at a school board meeting, that learning doesn’t stay in the classroom.

Ten Strands works where the first drops fall: equipping teachers, connecting districts, and opening doors for young leaders so that local actions can gather into a statewide current of environmental and climate action.

“None of this happens alone. Your partnership gives educators and students the room to act on what they know matters.”

Resilience, Progress, and Gratitude

As we reflect on this challenging year, we do so with humility and pride. A shift in federal power and sweeping environmental rollbacks led to the cancellation of many federal grants to environmental organizations. As those organizations turned to philanthropy for support, competition for funding intensified.

And yet—because of our steadfast donor community, strategic state-level partnerships, dedicated team, and shared leadership approach—we not only endured but achieved milestones that will shape the future of environmental literacy and climate action in California for years to come:

  • Established a historic baseline for environmental literacy and climate action by releasing groundbreaking data from the Data Initiative for Environmental and Climate Action in California’s TK–12 Schools, built from 1,000 school districts and all 58 county offices of education.
  • Empowered California educators with solutions-focused, age-appropriate environmental lessons called Seeds to Solutions, a free, K–12 open-education curriculum three years in the making.
  • Mentored high school students to shape policy and create local change through our second cohort of the California Youth Climate Policy Leadership Program, and launched the third cohort this year to meet growing student demand.
  • Made significant progress toward connecting students to the natural world as a regular part of their education by bringing together leaders across sectors to participate in the California Campaign for Outdoor Learning.

Thank you for being part of this urgent and essential work. Your continued commitment ensures we can prepare the next generation to meet this critical moment with courage, creativity, and hope.

Why this work matters

John Atwater and Diana Nelson

John Atwater and Diana Nelson have long cared about education and the environment. “I’ve come to realize how crucial it is to equip students with the knowledge and skills to understand and protect the world around them,” John says. “As parents, and now grandparents, the intersection between education and environmental issues has become even more important to Diana and me. The next generations will tackle complex challenges, so we need to foster a deep and enduring awareness of how they can impact and shape the future of the planet.”

“What drew me to Ten Strands is that they do the quiet, essential work that makes lasting change possible in schools. Their approach is like the ‘plumbing’ of the education system—connecting policy, practice, and people in ways that actually work,” said John. “It’s not flashy, but it gets the job done, and it’s joyful in its persistence. Ten Strands ensures that environmental literacy is integrated into the core of how schools operate, which is where real, lasting change happens.”

Diana believes that supporting Ten Strands is an investment in the next generation. “By helping schools weave environmental literacy into every part of learning, we’re giving students the tools to tackle climate challenges, think critically about their communities, and make thoughtful decisions about the planet. The future I hope to see is one where kids are empowered, communities are stronger, and the environment is protected.”

They also appreciate the collaborative nature of Ten Strands’ work. “To create change, they build networks, provide resources, and help educators feel confident to take action. Ten Strands has an impact in ways that compound. The work begins with one group of people, and it snowballs; in the end, the impact will sneak up powerfully. For us, supporting Ten Strands is about being part of a system that gets things done, step by step, and leaves a lasting impact on schools and students alike.”

John Atwater and Diana Nelson

Randi Fisher

“Growing up, I spent countless hours outdoors—learning, playing, and simply being immersed in the natural world. Those early experiences shaped my worldview and charted the course of my life. Later, as I began serving on nonprofit boards, I gravitated toward education and youth engagement programs because I had experienced firsthand the transformative power of learning in and about the environment. Over time, environmental education became a central theme of my work and a passion I have pursued with purpose.

“In its first decade, the Pisces Foundation placed environmental education at the heart of its mission. We knew there were thousands of outstanding programs across the country, but they weren’t reaching every child. We focused our grantmaking on strengthening and building the field so environmental learning could become a universal part of every child’s education. Ten Strands emerged as a key partner on that journey.

“Over the past decade, investing in Ten Strands has strengthened my belief that large-scale change is possible when vision, strategy, and persistence come together. Their leadership has moved environmental literacy from the margins to the mainstream in California’s schools. Today, more students are graduating not only with the knowledge to understand our climate challenges but also with the conviction and skills to take meaningful action.

“Schools are one of the most powerful levers we have to address climate change and protect our environment. The pace and scale of today’s challenges demand that every young person develop the capacity to meet them. By embedding environmental learning into the core of our education system, we equip the next generation to build a future where people and nature thrive together.

“Ten Strands has shown that with vision and persistence, environmental literacy can move from being a privilege for a few to a right for all.”

Randi Fisher

Dr. Veerabhadran “Ram” Ramanathan

“The challenges of climate change require urgent action related to mitigation, adaptation, and social transformation—the pillars of the MAST framework I helped formulate. Education is central to social transformation, which is why organizations like Ten Strands are so important. When I hosted the Climate Resilient California & Californians Summit, with Governor Newsom’s Climate Office in February 2025, I invited Ten Strands to present because of their pioneering work in advancing climate literacy with K–12 students. At a time when federal support for climate action is contracting, the role of the NGO community has never been more vital. I applaud Ten Strands and encourage them to continue their essential work.” 

Dr. Veerabhadran “Ram” Ramanathan

Terry Tamminen

“Ten Strands is addressing one of the most overlooked drivers of the climate crisis: environmental illiteracy. By integrating environmental literacy into California’s K–12 system—the largest in the nation—they are reaching almost six million students each year. This scale of impact ensures that future voters, consumers, and leaders are prepared with the knowledge and skills to advance equitable, science-based climate solutions. Supporting Ten Strands is an investment in resilience, informed decision-making, and the long-term sustainability of our communities.”

Terry Tamminen

Tony Thurmond

“California’s students deserve schools that nurture both their learning and their well-being. By advancing environmental literacy alongside sustainable, resilient school environments, we are preparing young people to thrive in a world that demands both knowledge and action. Ten Strands weaves together the partnerships, strategies, and systems necessary to provide all California students with meaningful environmental learning experiences and healthy, decarbonized learning environments. By developing free, solutions-oriented, age-appropriate materials in partnership with the San Mateo Office of Education, as supported by a grant from the California Department of Education, Ten Strands is empowering our young people to become learners and leaders in sustainable school communities across our state.”

Central Valley · Seeds to Solutions

The documentary that started at a faucet

Students sampling creek water during a field investigation.

Roxana Flores brought Seeds to Solutions water lessons into her Central Valley classroom. Her students followed the questions out of the textbook — interviewing neighbors, testing samples, and producing a documentary about their own water that went on to win an award. What changed most wasn’t the trophy: students began to see themselves as people whose voices carry.

Seeds to Solutions Brings California-Specific Climate Lessons to Every K–12 Classroom

San Diego · CTA–IFT partnership

A classroom that grows its own questions

A student presenting an environmental project to the class.

Through Ten Strands’ work with the CTA–IFT partnership, Anne Armstrong’s students explored aquaponics, food systems, and wellbeing as one connected inquiry. Along the way, Anne and her colleagues gained something durable — the confidence to keep teaching environmental literacy long after the project ends.
