We all know that recycling rubbish is very important. But sometimes it is not convenient when we can’t find a recycling bin anywhere.
Now a team of middle school students from the USA has solved this problem by designing their Recycling Bin app (应用程序).
This app encourages people to recycle. It provides urs with a map of local recycling centers. And it allows them to save places as favorites on it. This app also reminds urs to recycle.
The group of nine sixth-graders is from STEM Center Middle School. They came up with the idea as part of a school project for the Verizon Innovative App Challenge. Their school provided professional app training. It gave 10 teams Samsung tablets (平板)as prizes.
The Challenge wanted to develop students’ interest in science，technology and engineering. In this contest，students should show an app design that could solve a problem in their school or city. The nine students came up with the idea for Recycling Bin when they saw a need for more recycling.
"We hoped that this would really help a lot of people," Jaden Hilkemann, 12, told Time For Kids.
They kept their design easy so that anyone could u it. Now the free Recycling Bin app has been put into u.
"I was so excited when it appeared in the app store," Seralyn Blake，12，said. “A lot of my family members downloaded the app. It was pretty cool.”
