Basics of Light - Chapter Summary
In this fun chapter, you'll learn some of the key characteristics and definitions associated with light. Our instructors present the concepts of refraction and reflection, as well as the law of reflection. Additional topics covered include plane mirrors and how light is focused in the human eye. Once you read this chapter, you should be ready to do the following:
- Explain how light is created
- Identify the way light travels
- Differentiate between luminous and non-luminous
- Measure the angle of incidence using a protractor
- Stay safe in the sun
These kid-friendly, easy-to-follow lessons outline all the information you need to know. Each one is accompanied by a multiple-choice quiz so you can test your knowledge as you move through the chapter. If you need help with any of the concepts, contact an instructor for assistance.

1. Facts About Light: Lesson for Kids
In this lesson, you'll learn several interesting facts about light. You'll discover the characteristics of light and key definitions associated with light.
2. Properties of Light: Lesson for Kids
In this lesson, you'll learn how light is created. You'll also learn about the different properties of light by exploring how it behaves with objects in different ways: by reflecting, absorbing, or transmitting.
3. How Does Light Travel? - Lesson for Kids
Nothing that we know of travels faster than light. But how exactly does light move so quickly? Does it travel in waves like sound or in little particles? In this lesson, we'll investigate the scientific facts behind how light travels.
4. What is a Luminous Source? - Lesson for Kids
Although our eyes play an important role in being able to see, they actually are not the most important part of seeing. Without light, our eyes, no matter how great our eyesight, would not be able to see anything. This lesson will 'show' you how we are able to see objects.
5. Reflection & Refraction Lesson for Kids
Reflection and refraction are both important properties of light energy. When you look in the mirror you see a reflection of yourself. Using a magnifying glass to make smaller words appear larger is an example of refraction.
6. Law of Reflection Lesson for Kids
All energy can reflect and bounce, but on smooth surfaces, we can measure how the light will bounce. In this lesson, we will talk about reflection and how the law of reflection demonstrates the way that light will reflect.
7. Angle of Incidence: Lesson for Kids
This lesson will explore a unique angle that scientists call the angle of incidence. Continue reading to learn interesting facts about the angle of incidence, how to measure it, and how you see it in your daily life.
8. Plane Mirror: Definition & Uses
Imagine a world without mirrors. The way we conduct our lives would be very different. Would we have different views on the way we look? How would we know what was behind us while driving? In this lesson, we'll talk about plane mirrors and their uses.
9. Human Eye Lesson for Kids: Facts & Anatomy
The human eye is composed of many different tissues. In this lesson, we'll discuss the tissues that play a significant role in focusing light on the retina. We'll follow the light from outside the eye to the retina, through the optic nerve and to the brain.
10. Sun Safety Lesson for Kids: Tips & Facts
Our planet couldn't survive without the sun, but sometimes it can be harmful to us. In this lesson, learn about ways to stay safe in the sun and enjoy the rays!
