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...

Explore the connection of light, reflection, and mirrors. A comprehensive lesson introduces the basics of light in relation to reflection and mirrors. After an explanation of the vocabulary, the presentation shows how to create ray...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

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...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

You matter, unless you multiply yourself by the speed of light ... then you energy. Presentation covers the behavior of light as both a wave and a particle, light versus sound, space travel, why objects have colors, depth perception,...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Explore a land far, far away with a well-designed lesson that examines electromagnetic imaging as a way to obtain information about galactic structures. Learners begin to see the importance of looking beyond the visual spectrum to...
