COMPASS EXPERIMENT

Problem: How can we make our own compass?

Hypothesis: I think if ________________________________________________

_______________________________________________________________ then

_____________________________________________________________________

____________________________________________________________________.

Materials: magnet, iron needle, paper clip, water, cork or aluminum foil, marker, and non-iron bowl.

Procedure: 1. Hold your magnet in one hand, and stroke the needle over the magnet about 20-30 times in one direction only! 2. Make sure your needle is magnetized by attracting to a paper clip as a test. 3. Place your needle next to the magnet's North end. If it attracts, you know that end of the needle is South. Mark the North end of the needle with the marker. 4. Place the needle on the cork or aluminum foil, and float in the water. 5. Watch what happens to the needle.

Observations: What happened to the needle when floated in the water? How did you make a compass? Can you tell which direction is South? East? West?________________________________________________
