Mini-Environments
#ThrowbackThursdayFrom the ninth edition of the Boy Scout Handbook (1980)
"The environments in which you have roamed as a Scout have been as vast as your eyes could measure. But there are small environments that are also worth your study."
An aquarium, as the word tells you (aqua is Latin for water). is a watery mini-environment. for this you need a fish tank or bowl with a layer of clean sand on the bottom. Fill the tank with pond water. Anchor a couple of local aquatic plants in the sand. Then introduce a few water snails and a couple of minnows or other small fish.
If you can't get pond water, use tap water and let it stand a few days to lose its chlorine. And if you can't collect your own plants and fish, get them from a pet shop.
