Light waves and sound waves are the focus of this science lesson designed for 5th graders. Besides discovering how these waves travel, learners also discover the basic properties of waves, and analyze data tables and graphs. The...

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Data can travel on light waves ... who knew!?! Pupils explore the idea of using light waves to transmit data through space. They then build their own boards that detect a specific wavelength of light.

Explore physical science by participating in a visual spectrum experiments. Budding scientists identify the colors in the color spectrum and view the colors in class by utilizing cellophane, flash lights, and other arts and crafts...

Light is such a fascinating subject. This activity does a great job of illuminating the mysteries of light for your young scientists. A series of demonstrations which are explained in the plan should help your charges to understand how...

High schoolers 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...

Students examine how light waves travel. In this properties of light lesson, students observe how light travels in water, how light is reflected and refracted, and how light is pure energy.

Build a spectrometer to analyze properties of light. Scholars examine the spectrum from CDs and DVDs from two different light sources. Using the spectrum, they work to identify different elements.

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

Students explain the wave properties of light.

Learners 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 examine the physical properties of waves to explore the word crest and trough. They use toys to study waves in air, water and light.

Student groups rotate through four stations to examine light energy behavior: refraction, magnification, prisms and polarization. They see how a beam of light is refracted (bent) through various transparent mediums. Students investigate...

Seventh graders describe and conduct an experiment that identifies the physical properties of light. They explore sources of visible light and an electromagnetic spectrum. Students explain the conversion of one form of energy to another.

Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...

Students compare and contrast electromagnetic and physical waves. In this wave activity, students discover that all waves reflect, refract, and diffract energy. Students work in small groups to experiment with waves and evaluate the type...

Students identify different wave types and their characteristics.  In this wave instructional activity students complete activities by activating tuning forks and interpreting data. 

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

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 investigate solar energy and color. In this solar energy lesson, students assess the benefits of solar energy. Students discover that solar energy is attracted to darker colors and conduct an experiment using colored...

Eleventh graders explore the wave and particle properties of light.

Fourth graders engage in a study of sound pollution at their school. After a class discussion on what noise pollution is, learners are asked if they think there are areas of their school or community where noise pollution is a problem....

Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.

Students observe a demonstration on light. They construct a pinhole viewer, and explore and discuss the concept that light travels in a straight line.
