A terrarium is a self contained and sustained environment for plants and animals. Using recyclable and reusable materials, so far the terrariums are showing progress without tending. Using 2 clear plastic water bottles and re-purposed cloth or string. The directions on making them are found at the bottom of the page.
Using a mixture of top soil and compost, these terrariums are all set for the 5th Grade class to conduct an experiment using variables chosen by the class, like plants, soil, and fertilizer.
Due to the compost we used, every single terrarium was successful with surprise visitors of an unidentified bean sprout. The tops of the terrariums were popped off with how successful they were able to grow their sprouts.
