THIRD ROCK FROM THE SUN

OUR HERO 3050-0104

Do you have a favorite hero? Maybe Superman or the Power Rangers? (Okay, so the Power Rangers are out.) Well, maybe it is time to introduce you to the ultimate hero "MAGNETOSPHERE"! What? Never heard of him? Actually, Magnetosphere is not a he but an it. None the less, Magnetosphere is a super hero. You see, Magnetosphere is the magnetic field that surrounds the Earth. It helps to protect us by deflecting some very harmful particles that are ejected from the Sun. This magnetic field extends thousands of miles into space and is pear shaped. Click on the photo to the right to learn more about the Magnetosphere.

WHAT'S THE ATTRACTION?

Because the Earth is surrounded by a huge magnetic field, it acts like a giant magnet with two opposite poles. Can you name them? (Hint: big guy in a funny-looking red suit)

YOU'RE THE SCIENTIST

WHAT DID YOU LEARN? What rocky planet has the greatest Magnetosphere?

DO IT! MAKING A MAGNET

Do you want to make your own magnet? You will need a large nail with a small head and a bar magnet. Follow the directions below. (Reminder: Nails are sharp; be careful!)

1. Stroke the nail with one end of a bar magnet.

2. Rub the nail in the same direction each time.

3. Using the other end of the magnet, stroke the opposite end of the nail several times.

4. Slowly move the nail near some lightweight metal objects such as straight pins.

5. Record what happens. Why do you think that some metal objects will not be attracted to magnets?

MOOVING RIGHT ALONG

Do you know what a scientist that studies magnets is called? Well if you said Magnetologist, you are ... well, lets' just say you've taken this scientist business a little too far! Do you want to know more about magnets and cows? Wait a minute! Cows? What do cows have to do with magnets? To find out, moooove your finger to the cow and click. Well, what did you find out? Write a paragraph about the cow, magnet thing before you moooove on.
