Students Across New England Contribute to Climate Science Through NASA’s GLOBE Green Down

Engaging Young Minds in Real Climate Science

In fall 2025, more than 50 educators and over 1,500 young people across Maine and New Hampshire participated in NASA’s Global Learning and Observation to Benefit the Environment (GLOBE) Green Down, a citizen science initiative that transforms students into active climate researchers.[2] This groundbreaking program engages participants in tracking seasonal changes in plant life by observing and documenting leaf color change and leaf drop, contributing valuable data that scientists use to understand how ecosystems respond to our changing climate.[2]

The Science Behind the Initiative

GLOBE Green Down operates on a foundation of rigorous scientific methodology. Using standardized color guides and observation protocols, participants measure changes in plant health as autumn progresses, generating consistent, high-quality data that can be analyzed alongside observations collected worldwide.[2] This approach ensures that data collected by students in Maine schoolyards meets the same quality standards as observations from professional research institutions.

Students from pre-kindergarten through high school studied a wide range of tree species—including maple, oak, birch, ash, beech, poplar, and apple—by making repeated observations in their local environments.[2] In Portland, Maine, five elementary schools conducted observations in their own schoolyards as part of environmental literacy and science education programs, making the research accessible to learners of all ages and backgrounds.[2]

Building a Continental Dataset

What makes GLOBE Green Down particularly powerful is its geographic scope. Beyond New England, learners from Machias, Maine to British Columbia, and many locations in between, contributed observations, creating a geographically diverse dataset that reflects regional and continental patterns of seasonal change.[2] This distributed network of observers provides scientists with unprecedented insight into how climate variations across different regions affect the timing and progression of leaf color change.

The 2025 field season was led by the Gulf of Maine Research Institute and focused on supporting educators in taking learning outdoors while strengthening students’ scientific observation and data literacy skills.[2] This emphasis on outdoor learning and data literacy represents a significant shift in how science education engages young people with authentic research.

Fostering Inquiry and Critical Thinking

One of the most remarkable aspects of GLOBE Green Down is how it mirrors the actual scientific process. As students collected data, they began asking their own research questions—mirroring the inquiry process used by professional scientists.[2] Their questions explored differences in species behavior, the influence of sunlight, drought, wildfire smoke, and the built environment, and how these factors might affect the timing and progression of leaf color change.[2]

This student-generated inquiry transforms passive data collection into active scientific exploration. Rather than simply following instructions, young researchers develop their own hypotheses and investigate questions that genuinely interest them, fostering deeper engagement with climate science and environmental stewardship.

Strengthening Connections to Local Ecosystems

Educators reported that participation in GLOBE Green Down helped students develop a stronger connection to their local ecosystems while gaining experience working with real-world scientific data.[2] Many noted that learners were able to use their observations to discuss environmental change at both local and global scales, including potential climate change impacts on seasonal patterns.[2] This ability to connect local observations to global climate phenomena represents a crucial skill for the next generation of environmental stewards.

By studying trees in their own schoolyards and neighborhoods, students develop a tangible understanding of how climate change manifests in their immediate surroundings. This local-to-global perspective makes abstract climate concepts concrete and personally meaningful.

A Network Approach to Science Education

GLOBE Green Down operates as part of a larger ecosystem of science education initiatives. The field season was hosted through NASA’s Science Activation program as part of the Learning Ecosystems Northeast (LENE) project, which brings together educator learning communities across Maine, New Hampshire, Vermont, New York, and Massachusetts, fostering collaboration between school-based and out-of-school educators.[2] Through this network, educators support STEM learning, data literacy, and local ecosystem stewardship—empowering young people to contribute meaningfully to NASA-supported scientific research.[2]

This collaborative approach recognizes that effective science education requires coordination across multiple institutions and communities. By connecting diverse educators and learning environments, LENE amplifies the impact of individual initiatives like GLOBE Green Down.

Getting Involved

For educators, students, and community members interested in participating in NASA science, the GLOBE Observer app offers hands-on opportunities to collect and share environmental data used by scientists around the world, while building science skills and local environmental awareness.[2] This accessibility means that participation in climate science research is no longer limited to university laboratories or specialized research institutions.

Looking Forward

GLOBE Green Down exemplifies how citizen science can meaningfully contribute to climate research while simultaneously transforming science education. By engaging over 1,500 young people in authentic scientific observation and inquiry, the program demonstrates that students are not passive recipients of science knowledge—they are active contributors to our understanding of how Earth’s ecosystems respond to environmental change. As climate challenges intensify, initiatives like GLOBE Green Down provide hope by cultivating a generation of informed, engaged citizens equipped to address these challenges through science-based understanding and critical thinking.
