Chick and Dee Answered! T he sky is everything we see when we look up. During the day, we see blue light scattered from the atmosphere. We see the Sun, clouds, and sometimes the Moon. Birds and airplanes fly in the sky. Earth's atmosphere is part of it. At night, the sky is full of stars, planets, and galaxies, and again, sometimes the Moon. It does not really have an end because it is everything we see. The phrase "the sky is the limit" means there is no real limit! F ire needs three things to burn: fuel, oxygen, and heat. When you blow air on a fire, the oxygen can help the flames grow bigger. But when you blow on a candle flame, it goes out! This is because a candle burns with the help of its wax. The flame heats the wax. When the wax melts, it releases a gas that works with oxygen to keep the flame going. But when you blow on the flame, the wax cools down too much. It can't release its gas, so the flame goes out. Poof! 28 Chickadee T he last dinosaurs walked the Earth 66 million years ago, but it's fun to imagine what it would be like if they were still here. Would it be like Jurassic World, where the dinosaurs lived on an island? After all, dinosaurs and cities wouldn't mix. The Argentinosaurus stood as tall as a six-storey building! Can you imagine a big dino like that walking around office towers? And we'd also be spending a lot of time hiding from the ferocious T. rex. Yikes! Even though dinosaurs aren't around anymore, scientists did find a connection between T. rex and chickens. They figured out that chickens are the T. rex's closest living relatives. Wow!
