Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. Light contains photons which are minute packets of energy. When an object’s atoms get heated up, it results in the production of ...

Light Science Lessons and Activities for Elementary School Students, Grades 1-3
1. In the Can You See Through Me? lesson, students experiment with materials to see how they absorb, scatter, transmit, or reflect light. As they observe how much light passes through a material, students correlate their findings with whether a material is labeled as translucent, transparent, or opaque. Questions: Are there any materials that allow all light through? Are there any materials that absorb alllight? 2. What happens when you walk down the street and the sun is in front of you? A s...
Light Science Lessons and Activities for Grades 4-8
1. In the How Many Colors in a Rainbow? activity, students use a pan of water, the sun, and sheets of colored paper to create rainbows. The activity helps students explore how refraction creates the colors we see in a rainbow (or when using a prism). Different colors of light have different wavelengths, so when each color bends (refracts) and then bounces back out of something like a water drop, the colors all refract at different angles, which enables us to see a rainbow of colors. Questions...
Physics of Light Lessons and Activities for High School Students
1. In physics, students learn that the speed of light is a constant: 299,792,458 meters per second. However, this is only true in a vacuum. Light actually slows down when it passes through other materials. The Using a Laser to Measure the Speed of Light in Gelatin project gives students a chance to explore this firsthand by using a laser to measure the speed of light in gelatin. In this project, students use Snell's law (about the trajectory of light as it passes from one medium to another) a...
When teaching about visible light, students learn that light is a form of energy and travels in waves (similar to sound). As students explore the physics of light, they are introduced to the electromagnetic spectrum and the portion that constitutes visible light. In a variety of hands-on experiments and activities, students can explore the absorpti...

The energy produced by vibrations of electrically charged particles is light energy. The examples of light energy are: The energy that we use to cook food in a microwave oven is a form of light energy. Army men use radar to get the searchlight beam on the target. Radar systems that are used for ATC (air traffic control) use a form of light energy.
