The ants go marching
The people in the lab make food for the ants several times each week. All of the food for the ants is the same. On odd numbered days they carry the food up to the sites selected for the study. They put the food out on little squares of papers for the ants and then come back later to see who is there.
When the researchers go back, they look to see how many different species of ants are eating on each paper. So far, they have noticed that the papers that have many small portions tend to attract more different kinds of ants than the one with one big portion, which often only has one large species of ant feeding on it.
What conclusions might they draw from this? Could we conduct an experiment similar to this one in our own garden? How many different ant species do you think are living near our school?
