Dirty Water Experiment

Aim: To make a filtration plant using household materials.

Water Filtration Plant

Today 7/8Al and 7/8Wh had science, we did an experiment called dirty water. We worked in groups to do this experiment, in my group I had Addyson and Hope. This experiment actually made me learn something about the water in New Zealand. I learnt that it takes hours or days to make our water drinkable, so be thankful.  

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are: 

1. Kidney 
2. Swimming pool
3. A water jug
4. Coffee plunger

Materials

1. Bottle
2. Filter paper
3. Sand 
4. Pebbles/Stones 
5. Dirty water
6. Scissors 

Process

STEP 1

As a group we cut the bottle in half and timed the tops so they weren't sharp. 

STEP 2

As a group we put the top half of the bottle upside down in the bottom half of the bottle.

STEP 3

As a group we folded the filter paper in quarters and it was shaped like a cone. After folding the filter paper we added sand and patted it down like solid. After you do that pour pebbles/stones on top of the sand.   

STEP 4

As a group we added 2 cups of dirty water.  

STEP 5

As a group after adding the dirty water. We watched the water pour through the different ingredient in the funnel. 

Why it didn't go good?    - Conclusion

For this experiment the water was a meant to drip through but our poured, then slowly poured and then dripped fast.
