Hypothesis: If we filter the pond water with [|iodine solution] and then use a charcoal filter it after that, then the water will be safe enough for us to drink, because the iodine sterilizes it and then the charcoal cleans the rest of the bacteria that is left.

Materials : 1. Graduated cylinder 2. Pond Water 3. Iodine solution 4. Eyedropper 5. Filter 6. Charcoal 7. Petri dish

Procedure:
 * 1) Fill the pond water up to 500ml into a graduated cylinder.
 * 2) Put 6 drops of iodine solution 3.33 g/L into the pond water and let it sit for 15 minutes.
 * 3) While letting the pond water sit, set up your funnel with one piece of quantitate filter paper and 2 scoops of charcoal in it.
 * 4) Start to filter your pond water into a 500 ml beaker. Wait until its filled up to 200 ml.
 * 5) Also prepare your pond water to sit into your agar patri dish.
 * 6) Put 5 drops of the pond water into the agar, then use a inniculator wand dipped in bleach to spread the pond water around. Close and cover the side with para film.
 * 7) Repeat step 7 with the filttered pond water.
