Dirty Water

Dirty Water 

Hi guys, today we did an experiment on Filtration. 

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. We had to do dirty water test. 

Aim: To make a filtration plant using household materials.

Examples are:

1. Kidney  
2. Swimming Pool 
3. Filter Paper
4. Tea bags

Materials

1. One plastic bottle 

2. Sand 

3. Pebbles 

4. Dirty Water

5. Scissor 

6. Filter 

7. A Cup 

8. Tissue paper

Process: 

Step 1

Cut the bottle in half to make a plastic funnel and a container that the dirty water will go through.   

Step 2

Put the top half upside down on the bottom half. 

STEP 3

Add a layer of filter paper. I suggest that you should fold it in quarters then unfold to make a cone shape.

STEP 4

Put some sand inside the cone and place it in the funnel

STEP 5

After that add your one cup of pebbles on top of the sand.

STEP 6
Then it is time to add in your 1 cup of dirty water.

STEP 7 
Record you work

Conclusion: My group had the most clearest water because we folded our filter paper 3 times in steed of 2 times.
