Hello, everyone! Today, we’re going to learn about how people use light and sound to talk to each other. Let’s start with light!
Light is a special kind of energy that travels in waves. These waves come from things like the sun, stars, lamps, or even a campfire. When light waves bounce off objects and enter our eyes, we can see everything around us!
Imagine how hard it would be to move around in the dark. Light helps us see where we’re going and keeps us safe. But did you know that light can also send messages?
Have you ever seen a traffic light? It has three colors: red, yellow, and green. The red light means “stop,” the yellow light means “slow down,” and the green light means “go.” These lights help cars and people stay safe on the roads.
Near the sea, there are tall towers called lighthouses. They have bright lights on top that shine at night or in foggy weather. These lights help ships avoid crashing into the shore.
At home, we have little lights that tell us if something is on, like a TV or a computer. Some lights even let us know if we have a message waiting for us!
Now, let’s talk about sound. Sound is another kind of energy that happens when things vibrate. When these vibrations reach our ears, we hear them as sounds.
Think about a doorbell. It rings to let us know someone is at the door. A phone ringing means someone wants to talk to us. At school, a bell tells us when it’s time for class. And a coach’s whistle tells players when to start or stop playing.
Emergency vehicles like police cars, fire trucks, and ambulances have loud sirens. These sounds tell other cars to move out of the way because there’s an emergency.
The world is full of amazing lights and sounds. If you pay attention, you might discover something new and exciting!
That’s all for today. We hope you enjoyed learning with us. See you next time!
Light and Shadow Play: On a sunny day or with a flashlight, explore how light creates shadows. Ask the children to use their hands or objects to make different shadow shapes on a wall. Encourage them to notice how the size and shape of the shadow change when the light source moves. Discuss how light helps us see these shadows and how it can be used to communicate, like in traffic lights.
Sound Exploration: Create a simple “sound hunt” around the classroom or at home. Ask the children to close their eyes and listen carefully to identify different sounds they hear, such as a ticking clock, footsteps, or a closing door. Afterward, discuss how these sounds help us understand what’s happening around us, similar to how a doorbell or a school bell communicates a message.
DIY Light Signals: Provide the children with colored cellophane or transparent colored paper to cover a flashlight. Let them experiment with creating their own “traffic light” signals by changing the colors. Discuss how different colors can send different messages, just like traffic lights help cars know when to stop or go.

Welcome to Kids Academy!
Hey, Wally! What are you doing?
Just having a snack.
Hi everyone!
Today, we’re going to talk about how people use light and sound to communicate with one another. First, let’s start with light. Wally, do you remember how light works?
Of course! Light is a type of energy made up of waves that travel from a light source, like the sun, stars, a lamp, or a fire. Those waves bounce off objects and enter our eyes, allowing us to see things.
We all like light and feel uncomfortable in the dark. Without light, we don’t know where to go, and accidents can happen. Light not only illuminates our world but has also been used since ancient times to send messages.
For example, a traffic light has three bright lights: the red one tells us to stop, the yellow one tells us to use caution and slow down, and the green light tells us to go. These lights help cars and people avoid accidents on the street.
On seashores, people build lighthouses—tall towers with a light on top. This light is used at night or in foggy conditions to keep ships from crashing into the shore.
We also have light signals in our homes. Some light indicators tell us if an appliance is turned on, while others can inform us if we have a message waiting to be listened to.
However, light is not the only means of communication; sound plays an important role as well. Sound is a type of energy created when objects vibrate. When these vibrations reach our ears, we hear them as noise.
For example, a doorbell lets us know that guests have arrived. A cell phone ringing indicates that someone is calling. A school bell signals students to come to class, and a coach’s whistle tells them to start exercising.
Emergency service vehicles, like police cars, fire trucks, and ambulances, have sound alarms that alert other drivers to get out of the way when they are responding to emergencies.
The world around us is full of sounds and light. If you listen and look carefully, you might learn something interesting!
That’s it for this time. We’ll see you next time!
