As they grow, children begin to ask questions. Some hard, some even feared by adults.
A Research by the Institute of Engineering and Technology (IET) with the collaboration of more than four thousand people with children between 4 and 12 years reveals that when the questions are on topics related to science, technology, engineering and mathematics, 83% parents do not know what to say. This happens especially with basic questions such as what justifies that the sky is blue.
Two-thirds of respondents recognize that they already answered the wrong way, just not to admit they don’t know. And about 61% say they have used tricks or just didn’t respond.
“Parents need to know that it’s perfectly legitimate to say: ‘. I do not know, good question Let’s see if we can find the answer,'” explains Naomi Climer, president of the EIT.
1. What is photosynthesis? It is the process by which the green plants and some organisms use the sunlight to convert CO2 and water into sugars and oxygen.
2. How can the universe be infinite? The universe is infinite, but because of the speed of light we can only see the finite part. or the places where the light has reached since the beginning of the universe.
3. Why is the sun so big and there’re no people living there? The sun is much smaller than most of the stars we see in the sky. And it is impossible to live there because we would die of heat.
4. Why does the sun shine? The pressure that exists in the center of the sun causes the atoms to become hydrogen into helium. This is a process that takes the name of nuclear fusion, which occurs when the lighter elements are forced to stay together, to turn into heavier elements. This creates a lot of energy.
5. Can the moon fall? The truth is that, because of gravity, the moon falls towards the Earth. But it does this continuously, at high speed, it can follow the curve of our planet and will not collide. .
6. Why is the sky blue? The light coming from the sun enters the atmosphere and disperses in all directions. As the length of which is shorter, the blue light scattered more than purple and yellow, which gives the impression that occupies the entire sky.
7. Who invented the computer? We could say it was Charles Babbage and Ada Lovelace, in the nineteenth century, when they invented a brass the machine, or Alan Turing and John von Neumann, who later created the first electronic machines. So the best answer is: the computers were invented by many people.
8. How are bricks made? To make bricks, men uses a natural ingredient, clay.
9. How many species of dinosaurs existed? It is estimated that there was between 700 and 900 kinds of dinosaurs. But it’s hard to be sure because paleontologists are always finding new fossils.
