Sarah's class entered a large, dark room. Suddenly, lights flickered on, revealing a massive model of the solar system. The sun glowed brightly in the center, while planets of different sizes orbited around it.
A tour guide named Alex approached the group. "Welcome to the Solar System Room," he said with a smile. "Here, you can see how our planets move around the sun. Who can name all eight planets?"
Sarah's hand shot up. She recited, "Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune!"
Alex clapped. "Excellent! Now, let's learn some fun facts about each planet."
