Experts say that students usually need eight to ten hours' sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children study late. They will think their children work very hard. But not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger with his eyes still closed, begging for one more minute to sleep. Like thousands of students " early birds " in China, he has to get up before six every morning.

A report shows that without a good night's sleep, students seem to be weaker than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.

Experts have said that students should develop good study habits. So some clever students never study late, they are able to work well in class.

Maker Moment

Last year, Izzy Goldstein, 12, learned in science class that we can reduce air pollution by using natural energy sources, such as wind and solar power, instead of gasoline. This made her wonder what she and her schoolmates could do to help the environment. "Maybe if my school got a bike rack(架子),more kids would bike to school instead of depending on cars," Izzy told TIME for Kids.Rather than ask their school to buy a rack, Izzy and her friends decided to make a bike rack by themselves.

They came up with a design. They calculated how much wood they might need. They measured howlong the boards should be. They used power tools to cut them and put them together safely. And they didall this in their school's makerspace.

Makerspaces are workspaces where kids can learn to create objects using technology, engineering,art and design. These spaces often feature a mix of high-tech machines, such as 3D printers and robotickits(工具箱),and simple materials like clay and cardboard.

Izzy goes to the Harley School in New York. It is one of a growing number of schools across theUnited States with makerspaces. Makerspaces are largely inspired by Maker Faires(创客盛会),whichare events that give people a chance to share their creative projects. Each year, about 250,000 peopleattend the Maker Faires in San Mateo, California, and Queens, New York. Maker Faires have alsospread to countries around the world, including Egypt, France and Thailand.

Schools are introducing makerspaces to the curriculum(课程)because makerspaces give kids away to have ideas and build something from those ideas. Kima Enerson is a makerspace teacher atthe Harley School. But she says kids can become extraordinary makers in an ordinary classroom, too.In Harley's Lower School (pre-kindergarten to Grade 4), students learn about the basics of computersoftware. By third grade, they study coding and how electricity works. In sixth grade, they learn to safelyuse tools such as drills and saws. When students get to high school, Enerson shows them how to applytheir skills to solve global problems. "Throughout the process of designing, students are learning tocreate something to better the world," she says
