Do radio waves create light? It's more difficult to understand the things we can't see than those that we can. The simulation compares the relatively small range of visible light to the entire electromagnetic spectrum. It graphs the size...

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....

Does light affect molecules or does it go right through them? The simulation explores four different types of light: microwave, infrared, visible, and ultraviolet. Scholars alter the energy level of each as it is aimed at seven different...

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...

Light intensity varies by the strength of the light bulb as well as the distance to the light bulb. Pupils apply these concepts independently at first. They must solve for the light intensity as either the distance or the wattage of the...

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...

An interactive adds a bright touch to the holiday season with a learning game that challenges scholars to hang 250 Christmas lights. Once the outside of a house is decorated, participants have the choice to see their work light up to a...

Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...

How bright are your classes? An interactive lesson has scholars explore how light interacts with carbon dioxide in the air and the surface of the earth. They watch a temperature scale as light interacts with the environment.

How does a neon light work and does it actually contain the gas neon? An enlightening simulation encourages pupils to play with circuits and neon lights. They control the capacitance, resistance, and color of the bulb, and the simulation...

Scientists detected exoplanets by measuring how the brightness of stars changed over time. Young astronomers interpret and analyze the same data that led to exoplanet discoveries. They learn to apply light curve graphs and connect the...

In this electrical circuit learning exercise, students answer a series of 3 open-ended questions about light-pulse switches. This learning exercise is printable and the answers are revealed online.

In this online interactive reading comprehension worksheet, students respond to 15 multiple choice questions about Richter's The Light in the Forest. Students may submit their answers to be scored.

In this online interactive reading comprehension worksheet, students respond to 15 multiple choice questions about Faulkner's Light in August. Students may submit their answers to be scored.

In this literature worksheet, students respond to 16 short answer and essay questions about Faulkner's Light in August. Students may also link to an online interactive quiz on the novel at the bottom of the page.

In this literature worksheet, learners respond to 10 short answer and essay questions about Richter's A Light in the Forest. Students may also link to an online interactive quiz on the novel at the bottom of the page.

Scholars apply their understanding of circuits and electric pathways to many simulations. They move through three different activities and 18 questions, receiving immediate feedback after each answer. The lesson is part of a larger...

Star light, star bright, first star I see ... wait a minute, where did the star go? Scholars complete a simulation that measures the brightness of a distant star as another object passes in front of it. Learners move the passing...

For this online interactive reading comprehension worksheet, students respond to 25 multiple choice questions about Faulkner's Light in August. Students may submit their answers to be scored.

Get into the holiday spirit with math! As learners complete addition, subtraction, multiplication, or division problems, they earn Christmas lights that they can then use to decorate a virtual house.

Objects contain pigments that selectively absorb a wavelength of light, and our eyes only observe a very small range of these wavelengths. Scholars apply these two facts to three different activities. They identify the pigment in an...

Filters provide amusing changes to images in applications other than just Instagram! High school pupils apply their knowledge of colored filters to three different interactive sets of puzzles. They identify light colors that pass through...

What is the fastest way to get from point A to point B if you are going through two different mediums, such as air then water? Scholars explore the way light travels through air, water, acrylic, glass, and diamond as they answer this...

In this comprehension worksheet, students complete a quiz based on The Light in the Forest by Conrad Richter. Students answer 25 multiple choice questions.
