Hypothesis: The pond water will become cleaner if five drops of iodine are placed into the boiled water and it is filtered through charcoal, because the iodine will clean out the bacteria and the charcoal will remove the smell and remove any left over particles.

Procedure: 1) Boil 32 fluid ounces of water on a hot plate.

(boiled water on hot plate to kill some bacteria)

2) Place 5-10 drops of iodine in the water unless it is cloudy. (we placed the iodine into graduated cylinders)

3)Waited five minutes after iodine drops were placed in the water to clean out the bacteria. (we waited 5 minutes after the iodine was placed into the water)

4) After waiting 5 minutes charcoal filtration was used two times, and it was used to remove the smell and all the excess small particles.(we filtered the water with the charcoal)

5) Placed the bleach swab into each dish of water to feed the bacteria and let it grow. (non-filtered pond water after the bleach is placed in the dish(filtered pond water after the bleach is placed in the dish)
