El método cientifico , y sus etapas
Es aquella actividad que consiste en describir las leyes que rigen ka naturaleza mediante un proceso válido y fiable. Tiene 4 etapas 1) observacion - para poder dar lugar a grandes descubrimientos , las observaciones deben ser cuidadosas , exahutivas y exactas. 2)elabolación de hipótesis-la hipotesis cientifica es una suposicion que debe cumplir las siguientes condiciones: *Tiene que referirse a una situacion real. *Ha de formularse de la forma mas precisa posible y mediante variables concretas. *Debe ser observable y medible. (Si la hipotesis no cumple una de estas funciones, no es válida). 3)La experimentación- para saber si nuestras hipotesis son acertadas debemos comprobarlo de modo esperimental. *Un experimento es una forma especializada de observacion y su diseño quizás sea la etapa mas creativa del trabajo científico. *experimentar es repetir la observacion de un fenómeno en condiciones controladas tan específicas , que no dan a la naturaleza. 4) análisis de los resultados - es la elaboración de lablas y gráficas . *una tabla de datos está formada pir columnas y filas .
