Hace algunos años, cuando era un estudiante de secundaria, asistía con cierto fastidio a la clase de química, digo fastidio porque para mi no había nada interesante ahí, lo único que me resultaba un poco rescatable era el laboratorio, es decir, usar los microscopios, reactivos, quemar cosas, usar ácidos, hacer que explotara algo, eso era divertido. Pero la clase por más que le hiciera la lucha me resultaba bastante tediosa y si a eso le sumaba mi poca habilidad para la química en general, pues el resultado era siempre el mismo, rara vez acreditaba esa materia. Lo peor es que me siguió pasando lo mismo en el bachillerato, hasta que en la licenciatura en un esfuerzo sobrehumano de mi parte, la pude acreditar con una calificación decente.

En fin, a esa clase de secundaria había que llevar varias copias fotostáticas de la famosa tabla periódica de los elementos, y el show empezaba cuando tenia que colorear los distintos elementos de la tabla como los metales, metaloides, gases nobles y no tan nobles; De igual manera en otra copia, debía colorear los elementos de acuerdo a los orbitales y en las copias restantes ya no me acuerdo pero seguro algo tenia que colorear. Total que al final debía comprar otra tabla periódica en la papelería esta de una marca conocida debido a que la copia fotostática no tenia los datos suficientes y la de marca si, y todo esto para que al final no me permitieran sacar la dichosa tabla en el examen.

Bien, pues mi intención con esto no es criticar la forma como me enseñaron, tal vez era una buena estrategia para aprenderse los elementos de la tabla periódica, que no me gustara era otro asunto. Bien, pues lo que ahora quiero mostrarles es un sitio web donde construyeron una tabla periódica de los elementos totalmente interactiva (ptable.com), ya no hay que colorear a mano, el sitio web lo hace por nosotros al seleccionar las diferentes opciones. Uno puede variar la temperatura y ver que elementos están pasando del estado liquido al gaseoso y viceversa, cual es el punto de ebullición, fusión y todas esas cosas que a veces no son muy fáciles de entender. Así mismo uno puede consultar directamente información adicional como videos, fotografías y hasta información del elemento seleccionado en la Wikipedia, todo de forma integrada en el sitio web. Eso y muchas más monerías tiene este portal web, les dejo también un video con una demostración del portal «ptable.com«.
