You Will Need:
Shoebox lid, iron filings or metal objects (nuts, bolts, paper clips, etc.), a strong magnet
Put the metal objects inside the shoebox lid. Have your child hold the strong magnet underneath the box. As the magnet is moved, it will attract the metal pieces and they will move with it.
Be careful not to use items that are choking hazards for young children. If your child enjoys experimenting with magnets, be sure she knows not to put magnets on the computer.
