Children ‘s science questions What does human flesh taste like?

Children’s science questions also consider the taste of water, the first dinosaur, the poles of the earth, and what is common sense.

Oliver Komlosi, 12

Taste- and in addition to the sense of smell, our taste experience is affected by the senses of sight, hearing, and touch. In addition, it is shaped by our cultural perception of what is accustomed to being considered good food in different places.

With regard to human flesh, the cultural side is greatly influenced. Because we do not accept eating human flesh, there is little experience with it. However, eating human flesh has been described in books. The descriptions are based on the fact that someone has visited a tribe where the cultural tradition has been associated with eating human flesh.

It is known that human meat is, in principle, a typical red meat of a mammal, the color of which comes from a protein called iron-containing myoglobin. According to books on the subject, the taste of human meat is not much different from the taste of beef, for example.

There is no certainty about the oldest dinosaur species.

What was the first dinosaur?

Eemeli Sjöholm, 5

In South America has lived with several early dinosaurs at the same time. The fossils found in them, or petrified remains, are about 230 million years old.

It is not certain which of the fossils is the oldest, as they have been found in rock deposits in various places. It is not possible to compare places directly.

Early dinosaurs were species belonging to long-necked herbivorous dinosaurs Eoraptor lunensis, Panphagia protos, Guaibasaurus candelariensis, Saturnalia tupiniquim, Chromogisaurus novasi and Pampadromaeus barberena.

They were all quite small: the size from the muzzle to the end of the tail was about 1.5 meters. In addition, a small species of petodinosaur of the same size has been found Eodromaeus murphi.

Remains have also been found in South Africa Nyasasaurus parringtoni species. They are as old as 243 million years old. However, the species has not been judged to be a dinosaur, although it is very close in bones to one. It may be that when more samples of a species are found, it is found to be dino.

It is also possible that more fossils older than South American dinosaurs will be found in the future.

Taste differences come from substances that dissolve in water from the environment.

What does water taste like? And why does water taste different in different cities?

Raakel Heiniö, 9

Clean water does not taste like anything, but small differences always come from the environment due to water-soluble substances. The taste is influenced by the soil, for example.

Tap water from different cities comes from different sources. For example, drinking water in the Helsinki region is collected from Lake Päijänne, and drinking water in Tampere is a mixture of lake and groundwater. The groundwater of the calcareous land of Central Europe, on the other hand, tastes quite different from our sour groundwater.

Water treatment can also affect taste. If a lot of chlorine has been added to the water during the purification phase, it can taste even horrible. However, it is not dangerous to health. Taste is also affected by the water temperature and the tap water in the tap water, age and condition.

However, differences in taste are usually noticed properly only by tasting and smelling different waters in parallel. Tasting and smelling are also part of water quality monitoring in Finnish water utilities.

The pole points to a key point.

Why are the poles of the earth called poles?

Ellen Halsti, 5

Pole means many different things in Finnish. There is, for example, the pole in the stomach, the pole of the bicycle, the plus and minus poles of the battery, the pole of the earth, and also the center of something can be said to be the pole. The pole always means something very central.

The earth can be thought of as an axis of rotation coming out of the north and south poles. After all, there is no real axis like a bicycle, but the earth revolves around that point anyway. Illustratively, in English, the pole of the earth is pole, which also means a rod, rod, or pole.

If the earth happened to rotate differently, the poles would then be in a different place. It is therefore quite natural to call the poles the significant points around which the earth revolves.

There is use for both rural and urban reason.

There is often talk of a peasant order. So what is urban common sense?

Lotta Horn, 9

Rural-, everyday and peasant common sense are widely used terms to mean a practical view of things based on experience and genetic knowledge. Urban reason is not as commonly used a term, but there is a definition for it as well.

The most influential definition is made by the Finnish Language Center, which is responsible for developing the Finnish language. According to it, urban common sense means common sense, with an emphasis on quick decision-making in changing situations and flexibility of reason.

Urban reason is also associated with the term street intelligence, which is in English street smarts. The term is defined, among other things, by the Urban Dictionary. According to it, street intelligence means the ability to cope with dangerous situations and get along with many different people.

Both rural and urban common sense can be important. Depends on which one is needed more.
