Would an evil mastermind trying to take over the universe use explosives in space? A video that is part of a larger series approaches this question with physics of course! She explains the role of the atmosphere, the properties of waves,...

One of the learners in your class might be the first human to step onto the surface of Mars, or the first to design a spacecraft that collects data from the red planet. Prepare them for the adventure with a set of 24 lessons, complete...

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...

"To understand the phenomenon of color, it helps to think about light as a wave." This is a brief and very informative instructional video on what color is and why we are able to see it. Your young scientists will learn such terms as the...

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

Textbooks come in all shapes, sizes, and media these days. An electronic textbook resource offers Physics materials for a full course. The text offers an explanation of physics topics as well as examples of calculations and reading...

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...

Lasers attack hair cells from the outside in. Young scholars observe a laser hair treatment in slow motion. They watch as the pulses of the laser destroy the external hair. The Veritasium instructor then describes the process happening...

Ride the wave to an understanding of refraction! The first in a series of two inquiry-based lessons challenges learners to create transverse waves with two different types of springs. As their wave hits an object, they observe the change...

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function of...

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

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.

Time for a change in perspective. A video lesson explores the progression from 2-D to 3-D images. The instructor from the physics playlist first explains the workings of a traditional camera and compares that to the creation of a 3-D...

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...

We typically think of lasers adding heat energy, but lasers can be used for cooling, too! An episode of a physics playlist discusses the science of lasers. Learners watch how to place lasers to effectively slow subatomic particles.

The color of the sky depends on the time of day. Young scholars experiment with scattering different wavelengths of light to recreate the color of the sky. They observe both the longer blue wavelengths and the shorter red and orange...

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.

Are superheroes science fiction ... or just really fancy science? Go even further behind the scenes with the characters from Avengers through a video from the American Chemical Society's Reactions playlist. Curious chemists learn the...

Shed some light on the nature of shadows! Science sleuths investigate a 200-year-old theory that light will form a bright spot in the center of a sphere's or circle's shadow with a video from Veritasium. The resource explains the...

Is light a wave or a particle? The video recreates the double slit experiment with sunlight in public. Different individuals predict what they will see by looking into a dark box, which allows sunlight into it through two small slits....

How does a single photon show a phase shift? Using the interference pattern created by light traveling through a double slit, the resource asks whether the interference pattern would still show if only one photon of light is sent at a...

Explore the behavior of light waves with a lab activity. Scholars build new vocabulary through experimentation and observation. Using different mediums, they model reflection, refraction, transmission, diffusion, and scattering of light.

Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.
