Take a look at astronomy through the light lens. From radio to gamma, light waves exist in every corner of the universe. An enlightening PowerPoint presentation gives an overview of the different categories of light and then discusses...

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...

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,...

Beat the summer heat by exploring the properties of color. Scientists view a video explaining the relationship between light absorption and energy transfer using variables including intensity, time, and wavelength. A multiple-choice...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

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...

Explore a land far, far away with a well-designed lesson that examines electromagnetic imaging as a way to obtain information about galactic structures. Learners begin to see the importance of looking beyond the visual spectrum to...

Don't worry, optics is a light topic! The presentation covers reflection, refraction, fiber optics, mirages, prisms, rainbows, dispersion, mirrors, lenses, telescopes, diffraction, the human eye, and much, much more. Presentation is...

Electromagnetic waves travel though empty space, something no other wave type can accomplish. Young scientists learn more about the entire spectrum of electromagnetic waves. They sort cards and apply their knowledge to create models of...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

How can nanoparticles be used in the battle against skin cancer. Class members take on the question as they gather information about electromagnetic radiation, specifically ultraviolet radiation. Pupils learn about the mathematical...

Illuminate lightwaves, even those not visible to the human eye, in a concise activity about the electromagnetic spectrum. Pupils watch and listen to an animated video describing the electromagnetic spectrum as well as frequency and...

What is a physicist's favorite part of sports? Doing the wave. The presentation covers longitudinal, transverse, surface, and standing waves. It includes in-depth information on frequency, wavelength, period, amplitude, reflection,...

How does the color of the sky change from blue to reds and oranges to black? An illuminating lesson explains how light travels through different mediums using the sun's light as an example. By examining diagrams and illustrations, pupils...

It takes 225 million years for our sun to travel around the galaxy. The presentation covers astronomical units, light years, telescopes, types of stars, the life cycle of a star, and types of galaxies. This is the last lesson in a...

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Take a stretch, but don't wave goodbye. An interesting resource provides everything needed to present an introductory lesson plan on waves. Teachers present a PowerPoint defining the types of waves and their characteristics. Pupils use a...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Is the ocean blue at all depths? Nope! Explore the science behind the light spectrum in deep, dark waters. The lesson recommends watching The Blue Planet: Open Ocean—The Deep, but it's not integral, or you can substitute another clip....

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
