Here's what I would do, considering your extremely tiny budget. Just go to
Radio Shack and buy those circular ceramic magnets -- 5 for $3. Maybe they
are cheaper elsewhere.
Then buy some pencils, and you're all set. Or have them bring a pencil.
Give them two magnets to put on the pencil. See how the attract or repel.
Better with 3-4 magnets. Shows why our atmosphere has weight and it's
density decreases with altitude. You can also have them hold a magnet and
try to roll the other one on its outer edge without it falling. Easier
said than done. This will give them a challenge to try. Good concepts of
magnetism, friction, inertia, circular motion.
