As scientists begin to track ocean plastic from airplanes and even from space, a 12-year-old inventor hopes to help the effort with a device of her own: a robot that can move through the ocean identifying plastic, and that could eventually collect it as well.
“I have always loved marine animals and walking around the beach,” says Anna Du, a sixth-grader from Andover, Massachusetts, who is a finalist in the Discovery Education 3M Young Scientist Challenge. “One day I just noticed that there are plastics everywhere around Boston Harbor, and so I tried to pick them up and clean it up. But there were just so many that I wanted to make something to help that problem.”
