Soy Ken Kuwako, entrenador cient\u00edfico. Cada d\u00eda es un nuevo experimento.<\/strong><\/p>\n<p><span style=\"font-size: 14px;\">\u00a1Saludos a todos los profesores de ciencias! Hoy les traigo una idea fant\u00e1stica para crear una polea m\u00f3vil con materiales comunes que dejar\u00e1 a sus alumnos boquiabiertos.<\/span> \u00bfLes ha pasado que, al explicar en clase que &#8220;una polea m\u00f3vil reduce la fuerza a la mitad&#8221;, la reacci\u00f3n de los estudiantes es de total indiferencia? Es comprensible. Con las poleas diminutas de los cat\u00e1logos escolares, colgar pesas de 100g o 200g no permite sentir realmente esa reducci\u00f3n de esfuerzo. Adem\u00e1s, comprar kits caros para todo el grupo suele ser un golpe imposible para el presupuesto.<\/p>\n<p>Pero no se preocupen. Hoy les ense\u00f1ar\u00e9 c\u00f3mo fabricar una polea m\u00f3vil de gran tama\u00f1o por apenas un par de euros, logrando que sus alumnos exclamen: &#8220;\u00a1Hala, qu\u00e9 ligero!&#8221;. Con este material, sus clases de f\u00edsica ser\u00e1n mucho m\u00e1s din\u00e1micas y el aprendizaje ser\u00e1, sin duda, m\u00e1s profundo.<\/p>\n<h2>La Receta Cient\u00edfica<\/h2>\n<p>La clave de este experimento es un objeto inesperado que encontrar\u00e1n en cualquier ferreter\u00eda: ruedas para puertas correderas o armarios.
