Hypothesis: Our hypothesis is if we used the foul water procedure and use a hot plate, it will clean the water to make it crystal clear.

Procedure: To start off,
 * first**, poured the water into the funnel with just quantitative filter paper in there.
 * second**, We do the same with the tap water.
 * third**,we used sand and pebbles mixture to filter the water. we did that for both types of water.That was to get rid of the large particles in the water.
 * fourth**, we used about 3teaspoons of charcoal and put it into a funnel with quantitative filter paper to filter all the smaller particles in the water. we did that for both types of water. To make sure, it was all clean.
 * finally**, we heated a hot plate to clear out the last of the bacteria.

Materials:


 * Pond water Container
 * Hot plate
 * Sand
 * Beaker
 * Foam cup with holes on bottom
 * funnel
 * charcoal (in funnel, a black powdery substance)
 * ring stand
 * dropper
 * Pebbles
 * sharpie

Procedure with pictures:



First step: poured the water into the funnel with just quantitative filter paper in there.

First step: We did the same thing as what we did with the pond water.

Second Step: Used a pebble and sand mixture to clean the pond water

Second Step: did the same as the pond water. Cleaning it with sand and pebbles.

Third Step: Used Charcoal to get the smaller particles.

Third step: used charcoal for the tap water. did the same as the drity water.

Lastly, boiled the water to hopefully clean it. this is dirty water

Lastly, Did the same step as the dirty water but just with the Tap water sample.

Samples that were taken:





The end result after a few days
