Sixth graders observe light being separated into a color spectrum.  In this electromagnetic instructional activity students use a diffraction grating to separate light and compare light sources. 

Students are introduced to the wave nature of light. In groups, they discuss Young's experiment and how diffraction and interference demonstrate the wave nature of light. Using examples, they show constructive and destructive...

Twelfth graders research physical and chemical methods used in authenticating paintings (e.g., ultraviolet fluorescence and spectroscopy, infrared spectroscopy and reflectography, X-ray diffraction, microscopy, pigment analysis, and gas...

Pupils use experiments such as electron diffraction that show that particle have a wavelike nature. When they are fired through a thin slit, rather than scattering like hard spheres they interfere like waves. Students see that the...

Students explore the relevance and importance of data collection and analysis techniques that use different parts of the electromagnetic spectrum. They observe the basic concepts of the visible electromagnetic spectrum and the...

Assist your emerging scientists with construction of their very own spectroscopes. Individuals construct a spectroscope to identify elements used in varying lights within a particular environment. They conclude the activity with a...

This well-designed presentation covers many important aspects of the science behind light. In it, pupils view slides that have a lot of the important vocabulary associated with science, slides of famous scientists who made important...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

View LED lights through the eyes of a scientist. Young scholars learn to view light as a wave frequency and connect various frequencies to different colors on the light spectrum. A lab activity asks groups to measure the frequency of...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

The second installment of a seven-part series focuses on the refraction of light and how it affects the colors we see. Learners consider how this concept connects to biosensors for cancer detection.

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Ever made solar s'mores? Or recreated the solar system using peanuts? Astronomers young and old investigate all things solar using a variety of activities. Explore how the sun works, types of light it emits, and methods of charting the...

Don't have an electron microscope? Have your classes build the next best thing! A hands-on lesson plan asks scholars to build a model of Transmission Electron Microscope (TEM). They then use their models to identify the function of each...

Learners won't have to squirm when asked the facts after completing an intriguing lab investigation! Hook young scholars on science by challenging them to verify Hooke's Law using a gummy worm. Measuring the length of the worm as they...

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

Rainbows can teach us about the visible light spectrum. Learners observe multiple items that clearly display a rainbow to develop better connections. The lesson then explains wavelength using a rope to make waves.

Sixth graders examine how the sun's energy arrives as light with a range of wavelengths. They discuss the characteristics of light, examine the color of light using a spectroscope, and conduct an experiment using water and thermometers....

Students are introduced to the relationship between light and vision. In groups, they participate in experiments to discover how different wavelengths are divided in the visible spectrum. They record their answers and discuss their...

Learners 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 examine the properties of lasers and research their types and uses.  In this laser lesson students view several demonstrations.

Third graders study the concept of light as an energy source.  For this energy lesson students participate in a lab that show them the concept of light as an energy source. 

In this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.
