What are visual signals?

Visual signals are ways that things show their messages using pictures or shapes.

Imagine you and your friend are playing a game where you can't talk, only use hand signs to tell each other what's happening. That’s like visual signals: they’re the way things communicate without words, just by looking at them.

Think about a traffic light. It has three colors: red, yellow, and green. When it shows red, you stop your toy car. When it shows green, you go! The traffic light is using colors as visual signals to tell people what to do, just like hand signs.

Your dog also uses visual signals. If its tail wags fast, it means it’s happy and wants to play. If its tail stays still or goes down, it might be scared or sad. Your dog is sending you a message through the way it moves, all without saying a word!

So, whether it's a traffic light, your dog, or even a sign on the road, visual signals help us understand what’s going on around us!
