- Why Is the Sky Blue? | NASA Space Place – NASA Science for Kids
Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere Blue is scattered more than other colors because it travels as shorter, smaller waves This is why we see a blue sky most of the time Closer to the horizon, the sky fades to a lighter blue or white

- What Is Gravity? | NASA Space Place – NASA Science for Kids
Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other Earth's gravity is what keeps you on the ground and what makes things fall An animation of gravity at work
