**Hypothesis:** The Pond water will be clean if the water is filtered and bacteria is killed with a long wave UV light, then there will be no bacteria and the water will be clean and drinkable. This will work because the charcoal will filter out any large particles [|Disinfection of pond water] and the long wave UV light will eliminate all bacteria in the pond water


 * Procedure: **

* Before starting the experiment gather all materials listed below*

**Materials: **
 * Beaker
 * Graduated Cylinder
 * Stand
 * Charcoal
 * Funnel
 * Filter paper
 * Small Beaker
 * Ultra Violet Light
 * Timer
 * Agar Plate
 * Sterilized Brush/spreader

 * 1) <span style="font-family: 'Comic Sans MS',cursive;">Put filter paper into the funnel
 * 2) <span style="font-family: 'Comic Sans MS',cursive;">Place funnel with quantitative filter paper inside on the stand with the beaker underneath.
 * 3) <span style="font-family: 'Comic Sans MS',cursive;">Then put 4 scoops of charcoal into the funnel
 * 4) <span style="font-family: 'Comic Sans MS',cursive;">After putting in 4 tablespoons of charcoal, then put 16 millimeters of water, using a graduated cylinder into the funnel.
 * 5) <span style="font-family: 'Comic Sans MS',cursive;">After you do this step the water should be filtering into the beaker.
 * 6) <span style="font-family: 'Comic Sans MS',cursive;">When the water is fully filtered take the filtered water and place into smaller beaker and measure
 * 7) <span style="font-family: 'Comic Sans MS',cursive;">After you are finished measuring and have filtered into smaller beaker you may throw out the charcoal funnel.
 * 8) <span style="font-family: 'Comic Sans MS',cursive;">The second part of this experiment is to use the long wave ultra violet light and wave it over the filtered water for exactly 3 minutes using a timer.
 * 9) <span style="font-family: 'Comic Sans MS',cursive;">When done using the ultra violet light turn it off and get 3 agar plates, one should be controlled.
 * 10) <span style="font-family: 'Comic Sans MS',cursive;"> On one agar plate put 3 drops of filtered pond water, spreading it with a bleach stick.
 * 11) <span style="font-family: 'Comic Sans MS',cursive;">This first agar plate should be labeled with your initials and also it should say fpw (filtered pond water)
 * 12) <span style="font-family: 'Comic Sans MS',cursive;"> Using the second agar plate you grabbed put in 4 drops of regular pond water by spreading it with a bleach stick, and label it pw (pond water)
 * 13) <span style="font-family: 'Comic Sans MS',cursive;"> On the last controlled agar plate put 4 drops of tap water [[image:Long_wave_Uv_Lighttttttt.jpg width="370" height="156" align="right" caption="Long Wave UV light "]]
 * 14) <span style="font-family: 'Comic Sans MS',cursive;"> Label the last agar plate with your initials and write tap water.
 * 15) <span style="font-family: 'Comic Sans MS',cursive;"> After completing this you should take pictures of all your agar plates, and check the following day to see if the water you filtered water is safe to drink.
