題目列表(包括答案和解析)
Bicycles are a great way to get around. They are fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike – make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year’s Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, had three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country’s economic troubles.
“I see a problem in my country,” Renato said, “If you go to the forests in Peru, in some places you can not find electricity. If you go with my bicycle, you can turn on the lights.”
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender fastened to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country road. It’s made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
“You pedal the bike, and you can mix any drink you want,” Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.
