This will take passage to that the teacher teaches to them through examples and tasks as the physical things change and can be measured through the numbers. Volume Of the Bodies: The bodies have in themselves volume, and this in relation to their matter and mass. For example the Volume, of a three-dimensional figure, is the number that indicates the portion of space that occupies. It are expressed in cubical units. Of the water we can express similar things we measured since it by cubical fractions. When we listened to the expression been solid, liquid and gaseous.

We can imagine and observe as each of them represents volumes of the bodies. To the solid state him we can find three dimensions and one derived. Stop, width, length and depth. To the liquid state him we can find properties in relation to the class of existing liquids. Vapour pressure, the boiling point, the evaporation heat, the heat capacity, the volume by mol, viscosity and the compressibility. Also it studies how they are affected those properties by the temperature and the pressure.

Of the gaseous state, we can affirm that their elementary particles are less stable. And that is much more fast. Clear not in all the cases. Since inferiors exist gases with levels of good movement, but at this moment we dealed with those. That in particular they are affected by the pressure as a result of the temperature. The Teacher: The educational one would teach to the children to make figures of plastilina, cardboard and other elements. And soon it will cause that the respective measures are taken. In order that the small ones observe as the mathematical one is related with the physical existence. This for the solid state. In addition the teacher will be able to teach to the children basic geometry from these games. For the liquid state the educational one will be able to ask for the children to him who take containers that handle a good cubical measurement.
