With Explore the Planets, investigate the planets, their moons, and understand the processes that shape them. By G. Jeffrey Taylor, Ph.D. See our DVD collection.

I know it is dangerous to look at the sun with unprotected eyes during a solar eclipse so I would like to know some of the safe ways I can seeit.

You're right--you shouldn't look directly into the sun. The sun can damage your eyes even if you can only see a tiny part of it.

The easiest way to see an eclipse is by using two notecards. Poke a hole in one notecard with a pin and let the sun shine through the hole onto the second notecard. Hold the cards about half a meter apart. When the sun is normal, you'll see a circle on the notecard. When the moon moves in front of the sun, the circle will turn into a crescent.
