Build a Tiny Plant World! is the title of a new SciShow Kids video. The video explains how plants stay alive inside of terrariums and what you need to create your own plant terrarium. The video does a good job of explaining what students will need to create a terrarium and the elements within the terrarium create an ecosystem. If you would like printable directions for building a terrarium, take a look at this National Geographic page or this Climate Kids page. Both pages were recommend by SciShow Kids.
