Energy is necessary for change to occur in matter. Energy can be stored, transferred and transformed, but cannot be destroyed.
Resources cannot be aligned to this standard, browse sub-standards to find lessons.
Differentiate between kinetic energy, which is the energy of motion and potential energy, which depends on relative position.
Recognize the Sun is a major energy source for the Earth, and describes how it affects the planet’s surface.
Describe ways light can interact with matter, such as transmission (which includes refraction), absorption, and scattering (which includes reflection).
Explain that the human eye can only detect wavelengths of electromagnetic radiation within a narrow range; and explain that the differences of wavelength within that range of visible light are perceived as differences in color.
Recognize that most chemical and nuclear reactions involve a transfer of energy.
