In this module, students learn about the different sources of light, what causes darkness, and about shadows.

Investigate the science behind global warming with these classroom activities. Compare light and dark objects to see how they respond to light absorption and heat generation, and describe the albedo values of various materials.

This NSTA vetted source includes resources to allow students to make observations that prove objects in darkness need light to be illuminated. Included are assessment ideas, videos, examples, lesson plans, and photos of student work.

Watch as physicist, Patricia Burchat, discusses two basic ingredients of our universe, dark matter and dark energy, and the effects they have in the expanding universe. [17:09]

Young scholars explore how patterns and contrasts in language (diction, imagery, figurative language) reveal central ideas in texts and develop various motifs (light vs. dark, dreams vs. reality, high vs. low, etc.) in Romeo and Juliet....

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this...

An activity for students to explore how dark-colored materials absorb and emit more energy vs. light-colored material.

In this inquiry, students predict the best place to stargaze in Arizona based on the brightness of the night sky. Students are introduced to the concept of light pollution and Globe at Night, a global citizen science project in which...

Try this experiment to learn how to make things glow under a black light, why this happens, and some applications of this phenomenon.

In 2015, a high school senior named Tiffany Sun conducted a social science experiment and presented her results at the Intel Science Talent Search in Washington, D.C. The results of her experiment shed light on an age-old question: are...

[Free Registration/Login may be required to access all resource tools.] Presents igneous rocks, which form from magma, and the two types: dense, dark mafic and less dense, light felsic. Also covers Bowen's Reaction Series.

Beginning with an image termed the "Brief History of the Universe" this site examines (briefly, as noted) a timeline of the universe as dictated by the image. The timeline includes information on the big bang theory, the dark ages, the...

A lab activity where pond water samples are collected to observe the requirements for the growth of phototrophic organisms. To observe these requirements samples are separated into different variable groups. One group is incubated in the...

Examine how multiple light sources produce shadows of differing darkness and length. Move a player (with four light sources) around the field until your image matches the five other images on the page so you can identify where the player...

A biography of Melvin Calvin, the chemist who figured out how photosynthesis works. The emphasis of this biography is on his early life, the development of his interest in science, and his education.

Bill Nye explains the phases of the moon with an experiment using a baseball, a lamp on a table, a dark room, and a stool or chair that swivels. As the person moves around, the changes in reflected light show the phases of the moon. The...
