Infrared light is described as a light frequency we are unable to see. This clip shows how infrared works to send an "invisible" signal to turn on the TV. This clip doesn't explain why we can't see infrared but it does raise some...

In this light and the eye worksheet, students perform eight tests to show the blind spot in the human eye, to demonstrate Benham's disk, to show how polarized lenses work, to show how light scatters, to demonstrate fiber optic, rainbows,...

Students explore light.  In this physical science light lesson plan, students display objects on a projection screen and investigate how light absorbs, refracts, transmits and reflects. Students discuss common features of light based on...

Students explore constructive interference and destructive interference. For this light travel lesson, students follow procedures to discover how light waves travel and experience interference.

In this magnification instructional activity, students read about how lenses magnify images and how to determine the magnification of an image. Students divide ten by the focal length which is found to be the measurement from the center...

Students discuss the light spectrum and light waves as well as how the properties of light and color have contributed to important discoveries about properties of the universe. They research the term redshift and the redshift phenomenon...

Seventh graders explore stars. In this star lesson, 7th graders apply generalities about space objects to constellations and explore the differences between radio waves and light waves by answering essential questions in their research.

Students explore the concepts of light waves and sound waves. In this physics lesson, students complete activities that require them to investigate how light and sound waves travel.

Students explore light waves, refraction, and reflection. In this light lesson, students observe how light moves by using a flashlight. Students observe refraction and reflection.

In this waves worksheet, students compare the characteristics of sound and light waves and determine the wavelength, amplitude, and speed of a wave. This worksheet has 9 problems to solve.

In this Doppler effect worksheet, middle schoolers read information about the Doppler effect. Students answer questions as it relates to the pitch and wavelengths of a demonstration simulates what happens with the Doppler Effect.
