Mr. Kilgallon's Science Unit
LIGHT
Upon completion of the six week light unit, the students will:
know that light travels in a straight line unless it strikes an object
understand that liquid can be reflected by a mirror, refracted by a lens, or absorbed by an object
know that light interacts with matter by transmission (including refraction), absorption, or scattering (including refraction)
understand that something can be "seen" when light waves emitted, or reflected by it, enter the eye
understand that light is made up of a mixture of many different colors of light, even though to the eye the light looks almost white. Other things that give off or reflect light, have a different mix of colors
know that only a narrow range of wavelengths of electromagnetic radiation can be seen by the human eye; differences of wavelength within the range of visible light are perceived as differences in color
understand that different forms of electromagnetic energy have different wavelengths. Some examples of electromagnetic energy are: microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.
