PASSAGE: 5
Mr. Franklin is remembered as a scientist, inventor, printer, writer, and one of our country’s important early leaders. His ant experiment is just one of many interesting stories from his life.
6
One day he discovered ants crawling all over his kitchen shelf. Within minutes, a little jar of molasses was alive with them. He picked up the container and took out the pests.
7
But one ant stayed inside, swallowing the sweet, sticky syrup and storing it in the pouch, or crop, inside her mouth. (All worker ants are females.)
8
Because Mr. Franklin wanted to know if ants could communicate with one another, he gave this ant a challenge. He tied a piece of string around the mouth of the jar and hung it on a nail in the ceiling. Then he settled down to wait and watch.
9
Shortly, the insect crawled up the inside of the container, over the rim, and down the side.
10
But when she reached the bottom, there was, of course, no shelf! The ant dashed here and there and round and round. She zigged and zagged and eventually found the string.
11
Then a fast march up, a dash across the ceiling, and a race down the wall and over the floor led her to an opening that let her out of the kitchen. She vanished.
12
About thirty minutes later, Mr. Franklin spotted an army of ants moving like running water toward the wall. They swarmed up, flowed across the ceiling, and scrambled over to the nail holding the string. They lined up and marched, one after another, down the string and into the jar.
13
Before long, there were two lines of ants on the string, one line tramping down to get at the sweet food, and the other line parading upward. They were carrying home globs of molasses in their crops.
