Hypothesis: The filtration, appliance of the [|hydrogen peroxide] and [|boiling] of the pond water will eliminate the bacteria making it drinkable because hydrogen peroxide uses oxidation and the boiling of the water removes remaining bacteria.

Procedure: First, we filtered 100 mL of the Pond Water using quantitative filter paper. Second we added 20 mL of hydrogen peroxide (30% solution) of hydrogen peroxide to the filtered wate. Third we boiled the filtered water with hydrogen peroxide for 15-20 minutes. Lastly we applied the liquid to the agar. Then we filtered another 100 mL of pond water using the filter paper and added the hydrogen peroxide to the second liquid. Lastly we applied the second mixture to the agar.

Step 1- We filtered 100 mL of the Pond Water using quantitative filter paper

Step 2- We added 20 ml of hydrogen peroxide to the filtered water.

Step 3- We boiled the filtered water with hydrogen peroxide for 15-20 minutes at 110 degrees. (boiling point)

Step 4- Lastly we applied the liquid to the agar. Then we filtered another 100 mL of pond water using the filter paper and added the hydrogen peroxide to the second liquid. Lastly we applied the second mixture to the agar. Before And After Data:
