Imagine waking up in the morning after a good night’s sleep. You open your eyes, and the sun is shining brightly in the sky. Sunlight comes through your window, lighting up your room and helping you see everything around you.
When you look outside, the sunlight makes everything bright and colorful. Light is a type of energy that helps us see. Without light, we wouldn’t be able to see the sun rise or set, the colors of a rainbow, or the stars and moon at night. Without light, everything would be dark.
Darkness happens when there is no light. During the day, the sun is our main source of light. A source of light is anything that gives off light by itself, like fire, lightning, and the stars we see at night. But when the sun goes down, we need other sources of light to see.
We use lights in our homes, on streets, in cities, and even in sports stadiums. Car headlights, lamps, and flashlights help us see in the dark. These are called artificial sources of light because they are made by people.
Can you think of other artificial sources of light? Besides helping us see, lights are used in many other ways. Television screens, phone screens, and computer monitors use light for entertainment, learning, and talking to others.
Traffic lights, signals, sirens, and lighthouses use light to send important messages. Light is also important for plants. The sun’s light helps plants make food, which then becomes food for people and animals.

Light Detectives: Go on a light scavenger hunt around your home or classroom. Make a list of different sources of light you find. Are they natural or artificial? Try to find at least five examples of each. Discuss with a friend or family member why each light source is important and how it helps us in our daily lives.
Shadow Play: On a sunny day, go outside and observe how the sunlight creates shadows. Use your body or objects like toys to make different shapes and sizes of shadows. Notice how the shadows change when you move the objects closer or farther from the light source. Draw a picture of your favorite shadow shape and explain how it was created.
Light and Color Experiment: Gather a flashlight and a few colored transparent objects like plastic cups or colored cellophane. Shine the flashlight through the colored objects and observe how the light changes color. Try mixing two colors by overlapping the objects and see what new color you can create. Discuss why you think the light changes color and how this might be similar to a rainbow.

You wake up in the morning after a great night’s sleep and open your eyes. The sun is shining bright in the morning sky. Sunlight passes through your window and into your bedroom, lighting up the room and helping you see the things around you.
Look out your window, and the light from the sun illuminates everything outside too. Light is a form of energy that helps us see. Without light, you wouldn’t be able to see the sky light up as the sun rises and sets. You wouldn’t be able to see the beautiful colors in a rainbow or the stars and moon on a clear night. In fact, without light, you wouldn’t be able to see anything at all; you’d be in darkness.
Darkness is when there is no light. The sun is our main source of light during the day. A source of light is anything that emits light of its own, such as fire, lightning, and the stars we see at night. We also have artificial sources of light. At night, when the sun sets, we need other sources of light to see the things around us.
We use lights in our houses, streets, cities, and sports stadiums. Car headlights, lamps, and flashlights help us see too. Because things like lights, headlights, and flashlights are made by people, they are called artificial sources of light.
Can you think of any other artificial sources of light? Besides helping us see things around us, which is very useful, we use lights in other ways too. Television screens, phone screens, and computer monitors use light as well. They are used for entertainment, education, and communication.
Traffic lights, traffic signals, sirens, and lighthouses make use of light to send important signals and messages. On Earth, the light from the sun is really important in another way too: the energy in the food that plants make is then passed to people and other animals when they eat plants and other animals for food.
