Hypothesis: If boiled at a temperature of 100 degrees Celsius. The water will be safe to drink. [|Water temperatures above 160 degrees (70 C) kill all pathogens within 30 mins.]

Procedure: Step 1: Used a ring stand to hold up the funnel and poured the pond water through the funnel with the filtered paper, filtered paper collected the big pieces of particles. All the pond water will drip into a beaker.

Step 2: Wait until beaker filled to 74.3 and put the beaker on the hot plate and waited for it to boil. When it started to boil start time for 4 minutes so the the water can be pure drinkable water.

Step 3: Took the beaker off the hot plate and took some water from the beaker with a dropper and put one drop of the Treated pond water into petri dish. Spread the Treated pond water around with the wand and then covered it with para film. Do the same thing with the untreated pond water

Data: Before the water was treated and After the water was treated.



As you can see from this picture there is a large amount of bacteria in the pond water that was **untreated**.



As you can see there is a much smaller amount of bacteria in the treated water after a couple of days than in the untreated water.
