Mobile phones should be banned at school
Everybody says that mobile phones should be banned at school because they usually interrupt the class. However, I think that mobile phones are necessary because it is possible you need them when there is an emergency.
On the one hand there are some arguments to ban mobile phones at school. They annoy a lot if they ring in class. Students sometimes pay more attention to the mobiles than to the teacher. This is really the reason that teachers give, but students nowadays don’t admit any reason because they want their mobile phones to listen to music at the end of the class.
On the other hand if teenagers can’t use the mobile phone they will be very unhappy, bored and it may be necessary for an emergency.

4.1 The stages of learning as Dienes
The learning process is a process based on abstraction, generalization and communication. This process of abstraction is to accurately analyze and Dienes identifies six different stages in it:
Stage 1: introduces the individual in the middle => Game Free
2nd stage: review, manipulate, get rules => Structured Games
3rd stage: becoming aware of the common structure to games made
4th stage: representation of the common structure graphically or schematically => Stage representative
5th stage study of the properties of abstract structure, which implies the need to invent a language => Stage symbolic
6th stage: Construction of axioms and theorems => formal Stage
Her pedagogical approach

Natural disasters, how can we prevent them?

The Earth has suffered different types of natural disasters during its history such as tsunamis, hurricanes, floods and earthquakes, among others. We cannot avoid them from happening, but we can make them less damaging if we understand better why they happen and what can we do to prevent them. Some measures include:The creation of alarm systems that notify us from natural disasters. It is also important to take proper building plans if you are in an area of risk. Is it really necessary to have plans to evacuate people in case of emergency. They should also be carried out research after disasters and rehabilitation measures. Finally, we should take into mind that we are responsible in part for the... Continue reading "Ghjgh" »

System Types
The systems of equations can be
classified by the number of solutions that can arise. According to that case may have the following cases:
· Incompatible system if it has no solution.
· Compatible system if you have any solution in this case can also distinguish between:
or compatible system determined when it has a finite number of solutions.
indeterminate
or compatible system when it admits an infinite set of solutions.

FLAME TESTS
Different elements emit different colours when electric current is passed trough them. Different elements emit different colours due to the electron configuration in the atom.
Chemists use this theory to analyse materials for the presence of certain elements. As the chemists know the colours that are given off by various elements, they can determine the elements present in an unknown substance by the colours it emits. Traces off different metals are used in fireworks to produce the various colours when they are let off.
We can show this effect in the laboratory by heating various metals in a Bunsen flame. Wooden splints (soaked in water) are dipped in various salts (sodium chloride, lithium chloride, potassium chloride, barium chloride,
