Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

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...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

Pupils apply their knowledge of refraction to four different sets of challenges. Each of the first three focus on one variable's impact on the direction of bending. The fourth combines variables for greater challenge.

How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

In this online interactive reflection and refraction worksheet, students respond to 7 multiple choice and fill in the blank questions regarding the information included in the provided paragraphs.

The dress color debate of 2015 taught the importance of understanding how we see light. Scholars view a shirt under two different colored lights and then must predict what color the shirt will appear under a third light. They apply color...

In this online interactive literature worksheet, students respond to 20 short answer and essay questions about Edwidge Danticat's "Breath, Eyes, Memory." Students may check some of their answers online.

For this literature worksheet, learners respond to 30 short answer and essay questions about The Magic Mountain. Students may also link to an online interactive quiz on the novel at the bottom of the page.

In this online interactive history learning exercise, students respond to 9 short answer and essay questions about the achievements of Niels Bohr. Students may check some of their answers on the interactive learning exercise.

Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

This animation discusses light and the properties of light in a storybook format. The animations cover the colors of the rainbow (ROYGBIV) along with prisms, light waves, reflection, and refraction.

Defines the refraction of light and provides an applet for investigating it.

Manipulate variables and measure angles as light is refracted in this interactive simulation.

Why do we see certain colors? This interactive animation demonstrates the concept of the visible spectrum, and how we see the different colors of the rainbow.

[Free Registration/Login Required] In the scenario shown here, the laser cannot shine through the black barrier but can hit all three targets by reflecting off of the floor. Use the red dot to change the angle of the laser generator and...

Students participate in this skill-building activity where they explore how the location of an object in front of a curved mirror affects the characteristics of the projected image.

The Sound and Light interactive investigates these two forms of energy. Students will enjoy exploring how sound and light are created, travel, and can be controlled.

Find out about the physics behind those fun-house mirrors. Students manipulate a virtual optics bench to explore the images formed by mirrors and lenses.

[Free Registration/Login Required] Move the light source to see what happens to the reflected ray as you change the angle of the incident ray.

[Free Registration/Login Required] A simulation investigating why a diamond shines by looking at refraction, reflection, and total internal reflection.

You are on a mission--find out which alien invader is trying to blow up Earth! Take part in wiping crime from the universe and feel good about yourself in the process.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...
