Earth Day is April 22nd – Recycle a 2-liter bottle and make an Earth Day Terrarium!

This activity allows children to practice recycling and learn more about ecology,
environmental degradation, and the scientific process.

Terrariums are miniature, self-contained eco-systems. Once they are created, these closed environments can go for months unattended without even adding water. Moisture in the Terrarium evaporates from the soil and plant leaves, then condenses on the Terrarium roof and walls. The condensed water then falls down and re-moistens the soil in a continual closed loop process. As long as the top is sealed, this process will continue for months, perhaps even years. A fun project for children to create and observe!
