It Came From Outer Space

"It came from outer space" is a phrase that might apply to more things than you think! Although we're usually unaware of it, the earth is constantly bombarded with space rocks. They come from outer space as large rocks and are known as meteorites if they reach the earth's surface.

Most often, though, they burn up in the atmosphere long before they reach Earth. And of the few rocks that do drop to earth, most have become dust or small bits of rock by the time they reach the planet's surface. Tiny stone meteorites are hard to find, but iron meteorites are easy to collect.

What You'll Need:

  • Bed sheet
  • Magnet
  • Plastic bottle

How to Find Rocks that Come from Outer Space:

Step 1: On a still, clear night, lay a sheet on the ground. (Make sure you place it out in the open, away from trees.)

Step 2: Hold the edges of the sheet down with rocks or bricks so it doesn't blow away, and leave it there all night.

Step 3: In the morning, examine the sheet. You'll notice it's a little bit dirty. Most of this dirt is dust from the air, but some of it came from space!

Step 4: Take a magnet and pass it slowly over the sheet. If there are any iron particles from meteorites, they will stick to the magnet.

Step 5: Gently scrape the iron particles off the magnet and store them in a container, such as a plastic bottle or a film canister. Meteorite particles make a great addition to your rock collection!

Now try an experiment that uses the sun. Keep reading to learn what would happen if you allowed yourself to be sun-baked.
