Last week's Do Now investigated the controversial issue of using drones in the military. According to a recent article in the New York Times, about 2,500 people have been killed in drone strikes by the Central Intelligence Agency and the U.S. military since President Obama took office. And the program is expanding. 10 years ago, the Pentagon had about 50 drones; now there are 7,000 drones which range in size from large, Predator drones (costing $5 million or so) carrying laser-guided bombs, to tiny Hummingbirds, devices the size of insects and birds.

Below are most of the students' responses.
