In 2016, a elementary school in San Rafael, California, became the first U.S. school to replace all of its ordinary desks with raised desks that students stand at. Speaking to a reporter, one student at the school gave the standing desks a thumbs up. "You feel happier, you're less tired, and you're more active," she said. According to studies, children working at standing desks burn more calories and are more focused on tasks. However, some teachers and parents do not like the change. They are concerned that standing for long periods of time could cause students to be tired or posture problems. In addition, standing desks are more expensive than seated desks.

Someday we will all have robots that will be major parts of our life. They will look and behave much like real humans. We will be able to talk to these mechanical helpers and they will be able to respond in kind. Amazingly, the robots of the future will be able to learn from experience. They will be smart, strong, and untiring workers whose only goal will be to make our lives easier.

Carrots contain high amounts of vitamin A and are good for general eye health. However, carrots will not improve night vision. That myth goes back to a British lie during World War II. In 1940, the German air force, began bombing Britain at night. In response, the British government ordered people to turn off their lights; the government wanted to make it difficult for German pilots to hit their targets. A new technology allowed the British air force to track and shoot down the German planes without light. To keep the technology secret, the government told the media that their pilots could see the German planes because they consumed so many carrots. So people began to believe that eating carrots would help them see better in the dark.

Rachel climbed up the ladder. She got more and more nervous with every step she took. She finally reached the top, walked out on the board, and looked way down into the deep blue. Her friends had dared her, but could she do it?
What was Rachel afraid to do? How do you know?

The lights on tall communication towers warn pilots to avoid the towers when flying at night. Unfortunately, the steady red lights often used on towers have the opposite effect on birds: the bright beams attract and confuse them. Instead of avoiding the lights, the birds fly directly toward them, crashing into the towers or becoming entangled in power lines. Millions of birds have died this way. However, there is a solution. Unlike steady lights, flashing or blinking lights don't attract birds. In response to demands from conservation groups, the Federal Aviation Administration in 2016 began requiring towers to have blinking lights

Show-and-tell was a mandatory part of class when I was in fourth grade. I cannot even tell you how annoying it was. My house, when I was growing up, was a square box with small windows and yellow chipped paint. I wore clothing that my cousins had grown out of, or that my mother bought at discount stores. I had a few toys, but nothing shiny or electronic. I never went on vacations except to Cincinnati, and Harrisburg, Pennsylvania one time.

April Fools' Day is celebrated around the world, although it varies somewhat from country to country. In the United States, for example, it's a day to play practical jokes. In France, where the holiday is known as "April Fish", people secretly tape paper fish on their friends' backs. A common April Fools' prank in Portugal is to throw flour on someone; in Scotland, the most popular trick involves sending someone on a useless errand. Denmark celebrates April Fools' Day on April 1, but some people there celebrate again in May.

Exercise correctly to avoid injuries. Movements should be slow and controlled, not fast and jerky. A set of 12 repetitions of one exercise is enough to be effective. Exercising also helps you stay in shape and helps keep your heart and body healthy.

In March 2016, Death Valley National Park in California experienced a rare occurrence: thousands of yellow wildflowers covered the region in a "super bloom." Why was this unusual? Death Valley is the hottest and driest place in North America. The area's average yearly precipitation is just two inches, making it a challenging place for flowers to grow. However, in October 2015, the valley had received more than three inches of rain in some areas. As a result of the unusually wet season, wildflower seeds that had been lying dormant underground suddenly began to grow, producing an abundance of golden blooms.

Some people live in igloos. They are made from blocks of ice and snow, igloos are generally made in a circular shape. Gaps between blocks are packed with ice. A tunnel entrance allows people to enter and exit, but protects from cold winds. In addition, the snow works as insulation. Between it and the heat generated by people and oil lamps, the temperature inside an igloo can be moderately comfortable. This makes it a livable space
