Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

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 class...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Put the spectrograph to good use. Using a spectrograph individuals built themselves, young scientists examine and record the emission spectra of different light sources. They use the spectra to compare and contrast the compositions of...

Design a mission over the rainbow. Small groups spend several weeks together determining a mission related to spectroscopy. The teams build spectrographs and analyze the design to determine whether it will carry out the mission. At the...

Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Scholars learn the stories of the universe with a unit study on the cosmos. They model the universe, learn about the relationship with the electromagnetic spectrum, understand the big bang theory, and debate the existence of life on...

Somewhere over the rainbow ... the sky appears to be darker than below it? Why is that? A video from an interesting physics playlist illustrates the interaction between the visible spectrum and droplets of rain. It also doubles the...

How do we see what we can't see? An episode of a comprehensive physics playlist shows images of the smallest particles current technology can record. The instructor discusses current and past research on the makeup of subatomic particles.

Explore the difference between the two color wheels. The focus of the installment of a larger physics playlist is to explain the difference between mixing colored paints and colored lights. Viewers find that the components of their eyes...

Look beyond the light! An engaging activity introduces young scholars to the application of a spectroscope. The activity is the fifth in a series of six and focuses on the analysis of the elements of the sun.

What are the best materials for preventing sunburn? Young scholars consider this question as they test materials for the presence of ultraviolet light. They use a string of beads that changes color with different intensities of UV light.

Experiment with chemical compounds to produce the colors in fireworks! The lesson instructor demonstrates how adding high temperatures to specific compounds creates a colorful reaction—the same one people use to create fireworks. This is...

Why is light like the Navy? Because they both travel at c. The video explains what light is and what makes visible light different from the rest of the light spectrum. Scholars finish the video enLIGHTened about the concept.

By measuring the wavelength, frequency, and intensity of electromagnetic radiation, scientists determine the temperature, density, and composition of far away items. Scholars rotate through ten lab stations using a spectroscope at each...

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

According to the video, astronomy is like a jigsaw puzzle with an infinite number of pieces. The video explains the history and invention of telescopes, how they work, refraction versus reflection, and the changing technology. It...

A color-based video explains how scientists identified the colors of the rainbow and why we see different colors at different times. It introduces the idea of supernumerary colors and the disc shape of a rainbow as well.

Air is clear, so why do we see the sky as blue? The video explains the way light waves travel through the air and the result of our perceptions. It uses simple diagrams and illustrations to reinforce the variety of colors present versus...

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...
