Cara Lang is 13. She lives in Boston, Massachusetts, in the U. S. Last Thursday, she didn't go to school. She went to work with her father instead. Every year, on the fourth Thursday in April, millions of young girls go work. This is Take Our Daughters to Work Day. The girls are between the ages of 9 and 15. They spend the day at work with an adult, usually a mother, father, aunt, or uncle. They go to offices, police stations, laboratories, and other places where their parents or other family members work. Next year, the day will include sons, too.

The Ms. Foundation, an organization for women, started the program about ten years ago. In the U.S., many women work outside the home. The Ms. Foundation wanted girls to find out about many different kinds of jobs. Then, when the girls grow up, they can choose a job they like.

Cara's father is a film director. Cara says, “It was very exciting for me to go to the studio with my dad. I saw a lot of people doing different jobs.” Many businesses have special activities for girls on this day. Last year, Cara went to work with her aunt at the University of Massachusetts. In the engineering department, the girls learned to build a bridge with toothpicks and Candy. In the chemistry department, they learned to use scales. They learned about many other kinds of jobs, too.
