A multiple-choice quiz with three options for upper elementary students. Questions you can enjoy between classes or at home.

nose

Horses are animals that breathe through their noses. Unlike humans, they cannot breathe through their mouths and basically breathe only through their noses. Even when running very hard, they take in air only through their noses, so it’s said that if their noses become blocked, they can’t breathe.

Shinano River

The longest river in Japan is the Shinano River. The Shinano River flows through Niigata and Nagano Prefectures and is as long as 367 kilometers. It is called “Shinano River” in Niigata and “Chikuma River” in Nagano, and this change in name depending on the region is one of its characteristics. The Shinano River stores a large amount of water and plays a very important role in local agriculture and daily life.

thermometer

A Stevenson screen is a white box placed in schoolyards and meteorological stations. Inside the box are observation instruments such as thermometers and hygrometers, allowing for accurate measurement of temperature and humidity. The box’s shape and color are designed to reduce the effects of direct sunlight, rain, and wind.

wild boar

Pigs are animals that were originally wild boars, domesticated by humans over many years and selectively bred to be easier to eat and to have larger bodies. Today’s pigs are kept as livestock and have evolved to be useful to our lives, providing meat, fat, and more. Although their appearance and temperament differ, pigs and wild boars are very closely related.

Russian

The word “ikura” actually didn’t originate in Japan; it comes from Russian. In Russian, “ikra” refers to fish eggs in general. The term entered Japan during the Taisho to Showa eras and became established as a word that specifically refers to salmon roe.

about 15%

A pig’s body fat percentage isn’t that high compared to humans. It’s said that a healthy pig’s body fat is around 15%. Pigs are relatively muscular and have less fat than you might think. Although the word “pig” is often used to call someone fat, the funny thing is that pigs actually aren’t that fat.

lawyer

The jungle gym is a piece of playground equipment invented by a lawyer. Sebastian Hinton, a lawyer, came up with equipment for children to play on and obtained a patent in the United States in 1918. He originally devised it so his children could exercise and play, and from there it came to be used in parks around the world.
