Philippines Curriculum: Grades 1-10 - Science - Grade 8

investigate the relationship between the amount of force applied and the mass of the object to the amount of change in the object’s motion

infer that when a body exerts a force on another, an equal amount of force is exerted back on it

demonstrate how a body responds to changes in motion

relate the laws of motion to bodies in uniform circular motion

infer that circular motion requires the application of constant force directed toward the center of the circle

identify situations in which work is done and in which no work is done

describe how work is related to power and energy

differentiate potential and kinetic energy

relate speed and position of object to the amount of energy possessed by a body

infer how the movement of particles of an object affects the speed of sound through it

investigates the effect of temperature to speed of sound through fair testing

demonstrate the existence of the color components of visible light using a prism or diffraction grating

explain the hierarchy of colors in relation to energy

explain that red is the least bent and violet the most bent according to their wavelengths or frequencies

differentiate between heat and temperature at the molecular level

infer the relationship between current and charge

explain the advantages and disadvantages of series and parallel connections in homes

differentiate electrical power and electrical energy

explain the functions of circuit breakers, fuses, earthing, double insulation, and other safety devices in the home
