Have you ever wondered why it is bright during the day and dark at night? It's because Earth is always spinning! Earth spins around itself, and this movement is called rotation. When our side of Earth faces the Sun, we have daytime. When Earth turns away from the Sun, it becomes night. You can try this at home using a ball (Earth) and a torch (Sun). Turn the ball slowly and watch how day and night change! Fun Fact: While we sleep, Earth is still spinning—about 1,600 km per hour!
