GARDENING ON THE MOON If humans ever want to live on the Moon, we’ll have to figure out how to grow plants there. That’s a big challenge. The Moon has no soil or water—just rock and dust. It’s cold. And gravity is just one-sixth as strong as Earth’s. Even inside a shelter with soil, air, and water, could plants ever grow in such a harsh place? In January 2019, China landed a small pod on the far side of the moon. That’s the part of the moon that never faces Earth (but it does get sunlight). The pod was stocked with water, soil, and air. It also held plant seeds, yeast, and fruit flies. Once the pod landed, it watered the seeds. And safe inside the pod, tiny cotton sprouts became…

a half-time history of soccer

The First American Leagues In Central America and Mexico, the Olmec, Maya, and Aztecs played games with balls made from the sap of rubber trees. These ballswere bouncy, but heavy—a soccer-sized ball could weigh 10 pounds (4.5 kg). Players used their hips and bodies (but not hands or feet) to try to bounce the ball through a small stone hoop. The games were played as part of religious ceremonies. No one knows exactly what the rules were, but sometimes the losers were executed! Tsu Chu Around 2,300 years ago, the Chinese were playing a kickball game called Tsu Chu (or Cuju). Players tried to kick a leather ball stuffed with feathers through a hole in a high screen. Tsu Chu was part of military training—and also played for fun. Iceball North American Native people also…

who’s who on the field

Forwards or Strikers Try to get the ball to the goal and score. They are usually fast and accurate goal kickers. Mid-fielders Get the ball to the strikers and try to take it away from the other team. They do the most running and kicking. Defenders Their job is to keep the ball away from the goal and stop the other team from scoring. Goalkeeper One player stands inside the goal to keep balls out. The keeper is the only player allowed to use their hands. They wear padded gloves, because fast-moving balls pack quite a punch Referee Watches the players closely to make sure they follow the rules. The referee starts and stops the game, decides when a ball has gone out of bounds, calls fouls, and awards penalty kicks. When a player breaks a rule, the referee…

soccer tips for tricky players

Who will be the champions today? And how will they do it? Kickoff Before the game, the team captains flip a coin to see who gets the ball first. Each team stands on their half of the field, outside the center circle. Today, blue team has won the toss. When the whistle blows, Jovi plants her non-kicking foot firmly beside the ball, pointing the direction she wants it to go. Swinging her leg forward from the knee, she kicks the ball with the top of her foot, where her shoelaces are. The ball arcs across to Lily, who passes it to Lucas by kicking it sideways with the inside of her foot. Soccer players kick with the top or sides of their feet, not the toes. That makes it easier to control the ball. Dribble The…

a perfect ball

A perfect soccer ball should be round, light, and tough enough to stand a lot of kicking. It’s taken awhile to get there. In the Americas, Maya and Aztecs made balls from solid rubber. These jumbo bouncy balls were heavy. Players could be injured or even killed if the ball hit them. Leather covers soak up water. So balls often got heavy in the rain or if the grass was wet. Ball makers tried painting them with waterproof coatings. That helped a bit. Eventually, plastic replaced real leather. Now most balls are made of waterproof synthetic leather, to stay light and dry in all weather. In Europe, early soccer balls were made from blown-up pig bladders wrapped in leather. (The bladder is where animals store pee.) Animal bladders are not completely round, so…

a ball for everyone

Would you like a soccer ball that never goes flat? That lasts for years? That you can run over with a car, and it will still be good? Kids everywhere love to play soccer. If they can’t afford to buy a ball, they often make one out of plastic bags, trash, tape—anything that’s handy. These balls are lumpy and don’t last long. To help soccer-loving kids, some engineers started the One World Play Project. They designed a soccer ball made entirely of soft, strong foam. Air vents allow air to escape when the ball is crushed so it won’t burst. These vents also allow air in, so the ball inflates itself—no bladder or pump needed. Then they set up a company to get the balls to kids who need them.…
