Week 1 The Nature of Our Stuff

You’re likely wearing a shirt made from seeds, using a device made from rocks and the last meal you ate? It was probably made by bees. This week, we’ll learn how all the stuff we need and use comes from the Earth. We’ll also explore some small changes we can make that have huge, positive impacts on our planet.

Week 2 The Nature of Society

Humans get most of the credit for life as we know it, but our economy, inventions and jobs were actually inspired by systems in nature. In our second week of Earth School, we’ll learn how the natural world shaped human society and put some of Nature’s best inventions to the test!

Week 3 The Nature of Nature

Water, Air, Life, Climate, Habitat: In these Quests, our Earth experts will lead us in exploring the systems that make life possible on our planet. With hands-on activities and experiments, we will get to know these elements to better understand their nature and how they work. We’ll learn where exactly our water comes from, the importance of biodiversity and how big the ocean actually is (here’s a hint: bigger than you ever imagined).

Week 4 The Nature of Change

The news about our natural world often seems like something out of a horror movie: devastating wildfires, an unprecedented climate crisis, mountains of pollution. This week, we’ll learn about Earth’s fragile ecosystem in this time of great change, but take an active, optimist approach to exploring the many ways we can rebalance our planet.

Week 5 The Nature of Individual Action

This week’s Quests focus on solutions that will protect and enhance nature, with themes on recycling, composting, tree planting, urban gardening and using renewable energy. Unlock your inner Greta Thunberg and learn the practical ways we can all build a healthy future for our planet.

Week 6 The Nature of Collective Action

In the final week of Earth School, you’ll learn about the most powerful tools for protecting our planet: collective action and collaboration. These Quests will illuminate the path forward for us all to be conscious, nature-minded citizens of Earth, and invite others in our communities to join the fight to protect it.

About Earth School

Today, over 1.5 billion children aren’t able to go to school. In response to this education crisis, UNEP and TED-Ed – with the support of an incredible array of educators and partner organizations – launched Earth School, which consists of 30 days of nature-focused content and environmental adventures for learners of all ages. Each Quest includes a discovery video and quiz, combined with a series of engaging learning resources — all curated by environmental experts. Read more
