Learn how to build your own self-sustaining terrarium and observe a miniature ecological system! This short "how to" guide Maynard Okereke  demonstrates the water cycle and photosynthesis within a sealed container, ideal for beginners. Discover the magic of the biosphere in your own home!

Terrariums are sealed environments that allow you to observe natural processes like: Photosynthesis – where plants convert light into energy 🌞 The water cycle – including evaporation, condensation, and precipitation 💧

To make one, all you need is

  • A clear container with a lid
  • Rocks for drainage
  • Activated charcoal to keep things fresh
  • Soil to grow in
  • Plants that thrive in humid, closed spaces 🌿

Once sealed, your jar becomes a mini-biosphere, demonstrating how ecosystems sustain themselves without outside help. It’s a hands-on way to learn about the environment and biology—and it looks beautiful, too! Perfect for science lovers, DIYers, educators, and anyone curious about nature.
