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...

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...

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...

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...

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...

Examine earthquake intensities and ways to measure an earthquake through the comparison of the Mercalli and Richter scales. After completing the pre-lab worksheet, fourth graders compare high and low intensity quakes by testing...

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...

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...

Introduce third graders to energy waves with a hands-on geology activity, in which they answer questions and compare seismograms in the San Francisco Bay area. After a demonstration that shows how bigger waves indicate a...

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....

Surf's up! What causes the constant motion of Earth's oceans? Scholars discover the origins and types of waves in part nine of a 13-installment series. The resource illustrates wave behavior, their destructive power, and current research...

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...

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...

Get an up-close-and personal look at the sun from the safety of your classroom with this fun science application. Offering numerous activities, images, and videos, the resource supports children of all ages as they learn about the sun.

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...

Beautiful music doesn't just write itself, but if you ever feel bad about procrastinating, remember that Mozart wrote the overture to Don Giovanni the morning it premiered. Introduce young scientists to the elements of sound including...

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...

Here is an extensive reading resource that addresses our climate change crisis. It thoroughly explains the greenhouse effect, related Earth cycles, and the history of climate change. Use it as part of the intended unit, published by the...
