battery v. paperclips

PICKING UP CLIPS: VOLTAGE INCREASE VS. AMOUNT OF CLIPS
DOES INCREASING VOLTAGE PRODUCE MORE ENERGY?

PROBLEM:

How much voltage of the battery (6V) and the number of coils, can pick up paperclips?

 IV = voltage of the battery
 DV = number of paperclips
 Constants: trials, number of coils, battery

HYPOTHESIS:

If the amount of voltage (IV) is increased, the number of paperclips (DV) will increase as you pick them up. This is because the higher the voltage, the stronger the energy produced in the coil around the metal rod.

EXPERIMENT (PROCEDURE):

Materials used:
 6 volt battery
 Coils
 Partner(s) to hold coil and metal rod/battery
 Metal rod
 Paperclips
 Worksheet to record data

There are eight steps to the procedure:

 Get a 6 volt battery
 Get a long or short coil depending on your trial
 Get metal rod
 Get paperclips
 Wrap coil around metal rod (10, 20, 30, 40 or 50 times for each trial)
 Take ends of coil and attach to top of battery
 Take battery wrapped with coil and rod and lower it to pile of paperclips
 Record findings on data sheet
 Repeat steps one through eight by wrapping coil around metal rod at greater amounts

ANALYSIS

What I found in my data was that every time I wrapped the coil around the metal rod by ten, the number of paper clips counted that were picked up, increased. Something I noticed in my study was that as I increased the number of times I wrapped the coil around the rod by ten, the amount of paperclips would increase by fifteen.

CONCLUSION

My hypotheses was “if the amount of voltage (IV) is increased, then the number of paperclips (DV) will be decreasing as you pick them up”. The control group in my investigation was having no voltage in the battery. So no paperclips will be picked up. Something that might have affected the investigation are that the battery could have stopped working, there were no metal rods to use or no coils. One error that
