My family and I went on a roadtrip this summer to stay at my uncle's cabin on the lake! While we were there we created tiny forests inside some glass jars. Minnesota forests are perfect for making terrariums because there are many differents types of moss and fern. Terrariums are neat and easy to make, so here is what you need:- activated charcoal (find this in the aquatic section at Target etec)
- small rocks/gravel
-potting soil
-plants and water!
2. Pour a layer of activated charcoal over the pebbles to allow the air inside your terrarium to be filtered.
3. Place some potting soil into your jar.
4. Plant the plants and arrange your them in a way that is pleasing to the eye and give them some water!
Place the lid on top of your terrarium and put it by a window that does not get direct sunlight...you don't want to bake your terrarium in the hot sunshine :)
I found some bright moss, fern, and baby pine trees to plant in the terrarium. 
I was rained on a little while making it! 
tiny forest! For closed terrariums check to make sure it has enough water every now and then. Remove any dying leaves to keep bacteria from growing. If your terrarium has too much water leave the lid off to let it dry out a little bit.
The End
