AUTHOR:  Rebecca Boak, Raymond Gabaldon, Los Lunas, NM

GRADE LEVEL/SUBJECT:  (2-3)  Science

OVERVIEW:
     - Magnets are pieces of metal that have the power to
       attract other pieces of metal
     - Magnets attract objects made of iron or steel
     - Magnets have a 'N' and 'S' pole
     - Like poles push away or repel
     - Different poles pull together or attract

OBJECTIVE(s):
     Classify objects attracted and not attracted by
     magnets.
     Analyze materials of objects used
     Predict the poser of a unit magnet
     Make a nail magnet

RESOURCES/MATERIALS:  Large nail, Bar magnet, Small tacks,
     metal paper clips.

ACTIVITIES AND PROCEDURES:
1.   Experiment with magnets and various objects. Classify
     'Do's' and 'Don'ts'.
2.   Analyze the material each object is made of.
3.   Predict and then test the power of a unit magnet.
     Predict and then test the power of two unit magnets.
     Predict and then test the power of three unit magnets.
4.   Complete a worksheet on each of the above activities.
5.   Make your own nail magnet.

                        WORKSHEET #3

Make your own magnet.

MATERIALS:  Large nail, bar magnet, small tacks.

ACTIVITIES AND PROCEDURES:
1.   Test your nail by touching it to the tacks. It should
     not pick them up.
2.   Next hold the bar magnet in one hand and stroke the
     nail across it. Be sure you stroke it in one direction
     only.
     Stroke it around 50 times.
3.   Test your nail by touching it to the tacks. Presto, you
     have a magnet!
