  1. SCIENTIFIC METHOD MEASUREMENTS

  2. Aim : How can we review concepts related to the Scientific Method? Do now: Observe the picture and state a problem.

  3. El MetodoCientifico se utilizapara resolver problemas. Suspasos son: 1.Problema- Se escribe en forma de pregunta. 2.Buscar informacionacerca del problema(research). 3.Hipotesis- Lo queustedcreequeva a suceder. Yocreoque………………………. 4.Experimento- Incluye: Materiales,Procedimiento,Informacionorganizada en forma de tablas y graficas. 5.Conclusion-Donde se explican los resultados del experimento y si la hipotesisfuecierta o no.

  4. Medidas: Longitud: se mide con la reglametrica en cm. o mm. Mide el largo del objeto. Volumen-mide el espacioqueocupa un objeto.Semide Con el cilindrograduado. Masa- mide la cantidad de materia del objeto.Seutiliza La balanza triple paramedirmasa.

  5. Graficas-muestraninformacion en forma de un dibujo. Hay tresclases: lineal, barra y circular. Se utiliza la tabla de datosparaorganizardatos y hacer la grafica. La variable independiente se coloca en el eje de X y la dependiente en el eje de Y.

  6. Todoexperimentodebetener dos grupos: experimental-contiene la variable, se le da un tratamiento. control- no tienevariable,notienetratamiento. Siempre hay queutilizarmuchacantidad de muestra en un experimentoparapodercomparar los datos.
