Medieval Europe

The bullfighting ring’s soil is normally covered with sand. This causes a certain attrition to enter the legs of the bull and the soil. The attrition is present in almost all type of movement and is very useful in some cases and useless in others. The attrition can very be useful in the movement as, for example, when running, if it did not have attrition enters the leg of the bull and the soil, would not leave the place; it would be as if this walked on an ice track. For the physics area, we will demonstrate the different ones used forms of surface in bullfights and as it is the difficulty stop moving in them on them. We will make something similar to a race track, where it will have three different tracks: one with sand, to another one the normal soil (concrete or asphalt) and last, made the wooden one and lubricated with oil and/or petroleum jelly. The public will be able to run in these tracks to be able to observe the variation of attrition in each one e, after this, we will explain the reason this occurs and we will incase in the context of the race of the bull. Therefore without attrition the bull would not leave the place. In the biology area we will portray the cell of one of the bulls used in these races.

We will explain the function of each organela present in the cited cell and will show with clearness each one of them by means of a miniature. We know that Spain has some mechanisms and techniques of engineering and architecture in which it comes since Medieval Europe in the construction of churches and historical monuments. We intend to prove some techniques of construction by means of geometry, algebra and physics constructing projects of different materials and sizes.
