Earth Science Week 2026: Free Resources to Explore the Minerals That Power Our World
Every October, teachers, museums, and community groups celebrate Earth Science Week. Organized by the American Geosciences Institute (AGI), this annual event gives students a reason to look more closely at how our planet works and where it shows up in their everyday lives.
This year, Earth Science Week 2026 takes place October 11 to 17, 2026. Whether you have a full week of lessons planned or just a few minutes on Friday, it's easy to join in.
This Year's Theme: Critical Minerals for a Thriving Society
The 2026 theme, Critical Minerals for a Thriving Society, invites students to look closely at the mineral resources hidden inside the things they use every day. Phones, laptops, batteries, wind turbines, and even the fertilizers that help grow our food all depend on minerals pulled from the Earth.
AGI frames the theme around a few big questions: Where do these minerals come from? How are they found, mined, and processed responsibly? How does their use affect Earth's systems, from landscapes to water and air quality? And how can recycling and a circular economy help us use them more wisely?
Questions like these make science feel real to students. The theme ties geology to technology, engineering, economics, and local decisions, so it fits right into phenomena-based learning.
Download the Free 2026 Earth Science Week Poster
AGI has released a free 2026 Earth Science Week poster that follows the life cycle of critical minerals, from formation and mining to processing, use, recycling, and disposal. Hang it on a bulletin board or project it to kick off a class discussion.
The poster comes with ready-to-use learning activities on the 2026 resources page. Students can:
- Pick a mineral from the USGS critical minerals list and trace its full life cycle
- Explore how one stage of that life cycle affects the geosphere, hydrosphere, atmosphere, or biosphere
- Think about how repairing, reusing, or recycling a product at home could reduce the need for newly mined materials
- Weigh whether a newly discovered mineral deposit near their community should become a mine
AGI is also offering a free Geologic Map Day poster featuring Alaska's Seward Peninsula, home to one of the largest known flake graphite deposits in the United States. For even more ideas, check out the 2026 Earth Science Week webinars, which premiere throughout the week on YouTube Live.
Ideas for Your Classroom
Critical minerals are a great way to get students asking questions. Try holding up a smartphone and asking, "What is this made of, and where did it all come from?" Students quickly realize that the device in their pocket is connected to mines, rock formations, and people around the world.
From there, you can encourage students to:
- Ask questions and investigate. Have students choose one mineral and research where it forms, how it's extracted, and what happens to it at the end of a product's life.
- Think in systems. Explore how mining and processing affect water, air, soil, and living things, and how communities balance those impacts against the need for resources.
- Design solutions. Challenge students to propose ways to extend the life of everyday products through repair, reuse, or recycling.
- Explore careers. Introduce students to geologists, mining engineers, environmental scientists, and recycling specialists who work with critical minerals every day.
To take these explorations even deeper, EarthComm connects high school students to real-world geoscience challenges in their own communities, while OpenSciEd uses phenomena-based storylines to help students figure out how Earth systems work. Both keep the learning going long after Earth Science Week ends.

Celebrate Earth Science All Year Long
From the graphite in a pencil to the lithium in a phone battery, critical minerals are part of students' lives every day. This Earth Science Week, give them a chance to dig into where those materials come from and what it takes to use them responsibly.
