Materials

 * ===Two Magnets (to determine the Magnetic Force of attraction of)===
 * ===Spacers (made of card paper to place between the magnets)===
 * ===Weights (Steel washers)===
 * ===Hooks (to hang weights from bottom magnet while physically holding the top magnet)===

Procedure

 * ===Students place a specified amount of Spacers between both magnets.===
 * ===Student then add weights to the bottom magnet hook.===
 * ===When the force of the weights is greater than the magnet's Magnetic Force, the magnets will separate.===
 * ===Students record the data for each specific amount of spacers and the number of weights necessary to pull the magnets apart.===
 * ===The students then produce a line-graph relating the Magnetic Force of the two magnets vs the amount of Spacers between them.===

Conclusion
===Magnets come in many sizes and shapes. Magnets also come with different amounts of Magnetic Force. Students were able to determine that the more space between two magnets, the less Magnetic Force was available between them to hold together.===
