Chapter 3: Exploring the Internet

Exploring the Internet 🌐

A Big World on the Screen

The internet is like a giant library and playground on the screen. You have probably watched a video or played a game on it already. But where do those videos come from? Let’s find out what the internet really is, and how to explore it safely.

What Is the Internet? 🌍

The internet is a way for devices all over the world to share pictures, videos, games, and things to learn. When we watch a video or play an online game, we are using the internet!

Here is how it works. Your device is connected to other computers, far, far away. When you tap a video, your device sends a message: “Please send me that video!” A big computer somewhere else hears the message and sends the video back. It happens so fast that it feels like the video was already inside your device. But it wasn’t. It came from far away!

When a device is connected to the internet, we say it is online. When it is not connected, it is offline. Some things, like a drawing app, work offline. Other things, like videos and online games, need to be online.

What Is Wi-Fi?

We connect with Wi-Fi — a way to reach the internet without wires. At home or at school, there is a little box with blinking lights called a router. It sends invisible waves through the air, kind of like a radio. Your device catches the waves, and that is how it goes online.

When you are far from the router, like in a car or a park, there might be no Wi-Fi. Then some apps won’t work. That is not the device being broken. It is just offline!

Videos, Games, and Pictures Come from People 🎬

Every video, game, and picture on the internet was made by a person. Some are made for kids. Some are made for grown-ups. Some are very good, and some are silly or even wrong.

Here are two things smart tech helpers know:

The next video may start by itself. This is called autoplay. The device picked that video, not you. If it’s not something you should watch, it’s okay to stop it and tell a grown-up.
Some things on the screen are trying to sell you something. These are called ads. An ad might say, “Get this now!” You don’t have to tap it. You can just keep going.

Looking Things Up 🔎

We can use the internet to learn about anything — dinosaurs, planets, animals! A grown-up or teacher can help you search by typing words to find pictures and answers.

You can also search by talking. Some devices have a helper that listens when you say its name. It is a computer, not a person. It hears your words and looks for an answer.

Here is something important: not everything on the internet is true. Anyone can put things on the internet, and sometimes people make mistakes or tell fibs. That’s why we look things up with a grown-up. They help us find good places to learn, like a library helps us find good books.

Staying Safe with a Grown-Up 🛡️

The internet is fun, but we always explore it with a grown-up. Grown-ups pick apps and videos that are made for kids. They know which places are safe.

If you ever see something that feels scary, strange, or mean, that’s not your fault. Here is what to do:

Stop. Don’t tap anything else.
Turn the screen away or turn it over.
Tell a grown-up right away. They will help you.

Take Screen Breaks

Screens are fun, but our eyes and bodies need breaks. After you watch or play for a while, look far away, stretch, and go play. And screens go off before bedtime, so your brain can rest. Taking breaks is part of being a smart tech helper.

Chapter 3 Activity: Safe Explorer 🔍

With a grown-up:

Talk about one thing you like to do on the internet.
Find the Wi-Fi router in your home or classroom. Can you see the blinking lights?
Pick one animal. Search for a picture of it together.
Practice saying: “I will stop, turn the screen away, and tell a grown-up if I see something scary.”
Draw a picture of a grown-up who helps keep you safe.
