    ''Our most beautiful part is our bridge because we can make wind energy by this bridge and our main transportation is used by this bridge. '' The future city competition puts young teens in charge of building a city that can respond to a challenge. This year's challenge is resilience (重建能力) after a natural disaster like an earthquake. The models must be built with recycled materials for less than 100 dollars.

But behind this is some serious engineering. Each group has to present its city's resilience features to the audience and judges. ''The sea walls are made with concrete and steel to reduce the tidal waves impact on the shoreline. '' And it's about more than just infrastructure(基础设施). Judges want to know that you've thought about your citizens, too. ''If someone wants to design a building that's 50 floors, we make an agreement like maybe 20 of them have to be low-income housing. '' Engineering Outreach Group Discover (EOGD) has run the competition for nearly three decades. Director of programs Thea Sahr says it is an effective teaching tool. She tells of one boy who asked his teacher when they would get back to the real learning. ''You know the kind we were just sitting there reading the books and telling you the answers, '' and she said ''well what do you know about storm water that you didn't know last week. What do you know about scale? And you're having a really good time while you're doing it. '' He says this is learning. '' I want to do more of this. ''

The winners take home 7,500 dollars for their school’s science program, and get a trip to a science focused summer camp. This year's winners from Warwick Middle School in Pennsylvania say they also learned real-world skills like dealing with failure. ''The hardest part was trying not to get frustrated when something didn't work. And I think our team members really contributed to that. Communication is key. '' Listen, when you're building a city, engineering is just part of it.
