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

black

When we think of polar bears, we tend to imagine them covered in fluffy white fur, but the skin underneath is actually black. Their black skin helps absorb sunlight efficiently and maintain body heat. Thanks to this black skin and their transparent, light-transmitting fur, polar bears can live in extremely cold places like the Arctic without succumbing to the cold.

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.

Othello

Othello is a board game devised in Japan in the 1970s. It was originally popularized by a Japanese inventor, who refined and organized the rules based on the game “Reversi.” Today it is enjoyed not only in Japan but around the world, yet its origins lie in Japan.

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.

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.
