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...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

Nineteen word problems dealing with frequency, speed, reflection, and refraction of light are provided here. Empower your physics masters to manipulate equations for computing angles, focal lengths, image heights, and more! This is a...

This is a stellar overview of everything light and quantum! There are 30 multiple choice questions, none of them requiring any mathematical computation. There are a few diagrams to analyze: light rays striking reflective and refractive...

Think about your favorite place ... now, think about what it looks like at different times during the day. How does the change in lighting affect the colors you see? Young artists explore the tools available in digital art software to...

In this mind-bending activity, young engineers explore this question of whether or not light actually bends. Using holographic diffraction gratings, groups design and build a spectrograph. The groups then move on research a problem...

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

How do lighting types affect energy efficiency? Explore different types of lighting and the energy they use. Pupils learn about types of lights and calculate the energy used during a typical school year. They discover that being...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

If you set up a triad of mirrors into a corner figuration, they act as a kaleidoscope, bouncing light waves back and forth indefinitely, changing the light that your eyes perceive. Although the materials required are very specific and...

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Construct a maze in your classroom and have a blindfolded scientist act as a space rover, maneuvering unfamiliar terrain while another scientist plays commander. Classmates record the number of occurrences of the commander having to...

Here is a full-fledged investigation of light waves, the electromagnetic spectrum, and element spectra. Physicists research a scientist that contributed to our understanding of the behavior of light. They take notes on your lecture, and...

Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...

For this Earth Science worksheet, students read about the Greenhouse Effect and the difference between natural and amplified warming. Following, they answer ten short answer questions related to what they read about global climate issues.

Is it a bird? Is it a plane? It's super student! Physical science stars can fly during a unit on light as they see the reflection of one leg in a mirror, behind which the other holds them up. 

Here are some instructions for leading learners through a hands-on activity for investigating ultraviolet radiation. First, introduce them to light and refraction. Then introduce them to the electromagnetic spectrum. Finally, give...

A combination of informative text, photos, and graphics comprise this sharp show on electromagnetic radiation. Some slides mention hands-on activities for demonstrating concepts, so if you want to include them you will need to figure out...

A two-hour final exam covers a range of physics topics related to electricity and magnetism. It employs a variety of methodologies for assessing your physics learners' understanding and mastery of these concepts. You will need to review...
