Only a few types of animals live together in houses they make for themselves, a few bees and wasps, termites, ants and people. There are ant gardeners, soldiers, nurses, hunters, builders, trash haulers and farmers. Group living has advantages. No ant has to provide everything for itself. By working together, ants are efficient and successful.
Ants are also easy and interesting to study.
A simple ant house may be made by placing a jar with a lid inside a larger glass jar. The small jar takes up space, forcing the ants to tunnel near the outside of the large jar where you can see them. Use a nail to make tiny air holes in the lid of the larger jar. Wrap the jar with dark paper. Tape the paper so that you can gently remove it from time to time to check on the progress of your ants.
