Light Energy

In this lesson, students will learn everything about light. Light travels in the form of waves, in a straight line, at 186,000 miles per second. We see objects when light reflected off them enters our eyes. When light waves fall on an object they may be transmitted, absorbed, scattered, reflected, or refracted. For instance, light is transmitted when it passes through glass; scattered from particles in the atmosphere; and refracted when passing through a prism. Besides all the other important things it does, light helps us do some amazing things, such as helping us determine a star’s temperature through its color.

The video satisfies the 4-PS4-2 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-PS4-2. Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
