Kindle knowledge of how light travels by using this activity in your physical science curriculum. By setting up a candle flame or flashlight bulb and viewing it through a slit, observers of light see evidence of its wave characteristic....

Young scholars 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...

Seventh graders explore stars. For 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.

In this refraction activity, students will explore the property of light called refraction. Students will conduct a quick experiment to understand how light is refracted. Then students will complete 2 short answer questions.

In this light waves learning exercise, students will measure the wavelength of different light waves and then calculate its frequency. This learning exercise has 9 short answer questions and 10 fill in the blank questions.

Students perform 3 hands-on activities to help them explain the terms "crest" and "trough" as related to sound, water, and light waves. All three waves types have troughs and crests. The activities use toys to demonstrate the properties...

Students observe continuous and bright line spectra through a simple, inexpensive spectroscope that is suitable for classroom use and work through typical student laboratory exercises.
