Slide6procedure1)Grab your materials (1cm ,1/2cm and 2cm magnets), 1 stalk of lined paper, refrigerator, pa-per and pencil, and finally a ruler.2)Place the 1cm magnet on top of the paper on the refrigerator. If it can hold it keep adding more until it can’t hold any more papers. Do the same with the other 2 magnets.3) Record your results on a paper with a pencil.4) Add all 3 results from the 3 trails of the 1cm magnet, divide by three to get the median. Do the same with the other 2 magnets. 5) Make sure you repeat steps 1-4 2 more times, to get a total of 3 trails.

Slide9ConclusionMy hypothesis was correct. My data shows that the thickness of a magnet does affects its strength, because the1cm. magnet could hold 16 papers, the 1 ½ cm. magnet could hold 31 papers, and finally the 2cm. magnet could hold 37papers. So it means that the thicker the magnet the more strength. What did you learn...
Slide10ApplicationThis information can be helpful in the real world because if your not sure if the object you want to hang on your refrigerator is way to heavy you know that you need a stronger thicker magnet.
