This 12-year-old Girl Built a Robot to Find Plastics in the Ocean
Anna Du was walking along the beach when she noticed plastics there. She reached down to pick them up, and quickly realized it seemed impossible to clean them all up.
Du，12 years old at the time，tried to solve the problem like any good scientist-first，by doing a little research.That’s how she learned that million tons of plastics end up in the oceans every year.Then she got to work building something to help solve the problem:a remote-operated vehicle(遥控潜水器)，or ROV.Her ROV can move through water and find plastics on the ocean floor.
"She has a very good engineering sense to break down a problem like this and then go after it,"says engineer Casey Machado.
Du says actually getting her ROV to move through water well was not easy.She failed many times,but she never gave up trying and testing.
Du thanks her parents,who for years have taken her to student outreach activities,for supporting her interest in science and engineering.She says she has been able to meet students and scientists there.
"I know I want to be an engineer because I like building things to help solve world problems,"says Du,"But I'm not sure what kind of engineer I want to be yet."
11.What did Anna Du notice while walking along the beach
.
12.How old was Du when she did a little research to solve the problem
.
13.What can Du's ROV do
.

Dear friends,
As we all know,we have only one earth.But in recent years, many disasters happened on the earth and unusual weather appeared very often.As students,what should we do
First,we should let more people know the importance of environmental protection. Second,we should save water and energy in our daily life.Third,in order to reduce air pollution, it is better to go to school by bus,by bike,on foot or other public transportation instead of using private cars.Fourth,we should learn how to sort garbage and use few plastic bags.Last,we should protect wild animals,and don't eat them.
If we all keep doing these things,I believe the environment will be better and better.Let's try our best!
