Go outside and pick up a rock. Where do you think the rock came from? How did it get there?
Many rocks come from the earth. But some rocks on Earth are from outer space!
There are lots of pieces of rock in space. Rocks can fall to the earth from space. When they fall through the air, they can look like a streak of light. These are called shooting stars! Then, they land on the ground. Now you can go out and find them!
