The life of a star. 5th grades.

Recently, at class, many of you asked me about stars. How are they born? How do they produce energy? How do they die? In this report I will try to answer all these questions shortly:

1.- How are they born?

The birth of a star is something very mysterious. It happens inside a giant nebulae. A nebulae is a great mass of hydrogen. In accordance with scientists and astronomers, in the birth of a star the hydrogen atoms begin to stick together, becoming into a bigger and bigger ball. Finally, when the ball is big enough, there is an ignition: the mass of hydrogen, due gravity forces, starts a fusion process. Thus, the star is just born.



2.- How do stars produce energy?

As said before, a star is born just when gravity heats the hydrogen, initializing a fusion process. And what is a fusion process? Well, fusion is a type of nuclear energy. It takes place when two similar atoms stick together, becoming a different one. In a star, the fusion is based on hydrogen: two hydrogen atoms become into one helium atom. During this process a great amount of energy is released. Energy that we perceive in form of light, heat and other type of radiation.


3.- How does a start die?

The amount of hydrogen which a star has is finite. So, when this hydrogen is over, theoretically the start should die, like a candle. But instead of this, the star becomes stubborn. "Don't I have hydrogen? Let's fusionate helium". And the helium fusion begins. However, this type of fusion is not as efficient as hydrogen. So in the process the star makes up for it by growing. Then the helium also runs out. But the stubborn start refuses to stop, fusionating now Beryllium. Then, Carbon; then, Magnesium. Meanwhile, the growing process continues. At one point the star cannot grow any more. Now only two things can happen:

a) If the star is very big, it collapses, and then bursts in a huge explosion (a supernova). 

b) If the start is medium size (like our Sun), the growing process ends in the releasing of hot matter.

In both cases the only remaining thing is the core of the star. If the star is big, the core is a neutron star. If the star is medium size, or small, the remaining thing is a white dwarf star.

In the following video, a recreation of the end of our Sun. Do not worry; in accordance with scientist, this will not happen tomorrow. At least, 5.000.000.000 years remaining.


Professions. 6th grade B. Video.

Watch this video and try to find out the professions of these people. On Wednesday the 20th we will watch it at class. And who knows; maybe at the exam...

Dangerous jobs. 6th grade B.

Today, before games, we will read a bit. Concretely we are going to learn about the five more dangerous jobs in the world, in accordance with statistics:

5.- Venom milker.

This job consist in to get poison from venomous animals. The poison is used for making the antidote, which can save your life if, for example, a cobra has bitten you. Needless to say that this job is dangerous.

4.- Ice road trucker.

In some cold countries, like Sweden, Canada or Russia, rivers and lakes get frozen when winter comes. The ice is so thick that it can endure the weight of big trucks and trailers. However, from time to time the ice breaks, and well... In that case it is not nice to be inside a truck cabin. 


3.- Sulphur miner.

Miner is one of the most dangerous professions. And even more if you have to climb a volcano for extracting sulphur rocks. These people usually die young because of toxic gas released from hot cracks.

2.- Landmine remover.

During war it is common to bury mines for protecting determined areas. It is the so called "mine field". Then, when war is over, it is necessary to remove these mines. Here takes place the profession of "Landmine remover": a guy which, with a metal detector, goes here and fro looking for these deadly weapons.


1.- Lumberjack (woodcutter). 

In big forest areas from Brazil, USA, Canada... we find people who work as lumberjacks. Their mission: to cut down and extract from forest very big logs. Every year dozens of these workers die crushed by the weight of giant logs. They also work with very dangerous tools: axes, chainsaws, heavy machinery, cranes, stell wires...


Are we alone in the universe? 5th grades.

The Earth is a little blue marble floating on the space, with very favorable conditions for life: water, atmosphere, magnetic field, oxygen... Out of here, life seems impossible: extrem hot over 5000º, or extrem cold ( - 273º); solar storms, radiation... Very hard conditions indeed. However, we do not know if there is (or not) life out of our plantet. Let's see some arguments in favor and against the existence of aliens:

In favor: Universe is very wide, even vast. So big that cannot be conceived by our human minds. Billions of galaxyies with billions of stars, many of them surrounded by dozens of planets... Why not possible that in one of those plantes life could arise?

Against: If there is life out of the Earth, How is that no Alien has come to say hello?

In favor: They haven't say hello because we are not enough important for them. If you meet an ant, "would you try to communicate with it?"

Against: Life, as we know it, is a complex thing which needs a lot of requirements for arising: water, carbon, oxygen... It is not very common to find all these elements together in a planet.

Gliese 667cc, a possibly habitable planet
In favor: As said before, the universe is very very vast. NASA is constantly finding planets defined as "habitable": this means that in those planets there is water, athmosphere with oxygen, etc.

Against: Let's assume that there is intelligent life out of the Earth. Here comes the problem of distance. The closet star to our Solar System is Alpha Centauri, which is 415.900.000.000.000 km far. And this is the closest one. Imagine the distance which an alien had to cover from remote areas of Universe. It would take hundred of years to travel from one to other habitable planet.

In favor: Alien's technology could be more advance than ours. Maybe they have found a way for travelling great distances very fast; for example, curving the space - time line.

The discussion could be eternal. What do you think? In favor or aganist the existence of aliens?


The universe. 5th grades.

Here I let you a couple of online activities for studying. The first one is about general elements of the Universe; and the second is about the planets in our Solar System.
