How to make a Closed Terrarium?

A closed terrarium makes an excellent science project for students of all ages. The terrarium can be used to study the water cycle, the growth of plants, and the interaction of living things in a self-contained environment.

Creating a closed terrarium is simple and can be done with a variety of materials. All you need is a clear container, such as a jar, aquarium, or plastic container with a lid. You will also need soil, charcoal, gravel, and plants.

Begin by layering the bottom of the container with the substrate, charcoal and gravel. This will provide the necessary drainage and aeration for the plants. The plants can be placed in small pots or directly into the soil. Be sure to water the plants before closing the terrarium.

Once the plants are in place, close the container.
