WHAT IS MAGNETISM?

 

POLES

 

Art:A basic law of magnetism is that unlike poles attract each other. Two bar magnets can illustrate this. One is hung so that it swings freely. A pole of the second is brought, in turn, near each of the two ends of the hanging magnet. One end of the hanging magnet is attracted.

Directions:

1. Consider a question that you would like to answer.  You may select a question from below or you may develop your own by looking in any of the books provided.

2.  Read some of the science discovery log forms in this folder to see what other student scientists have investigated. 

3.  Begin a science discovery log sheet of your own.

4.  Conduct your investigation.

5.  Complete your science discovery log sheet.

6.  Add what you discovered to the Book of Discoveries.

 

Some questions that you may want to investigate:

1.      Or how far can you move a magnet?

2.      Do different magnets have different strengths?

3.      How does a magnet affect a compass?

4.      How can you use a magnet to pick up a piece of paper?

5.      Will does water affect magnetism?

6.      What objects stick to magnets?  What characteristic do these objects have in common?
