Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

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

Examples are:

1.  oil
2.  air
3.  pool
4. water

Materials

1.Funnel

2. Container

3.Filter paper 

4  plebes 

5. sand 

6. dirty water

7. cup

8. 

Process - ( use verbs or doing words in each step )

Step 1

Cut the bottle in half 

Step 2

Put the top half upside down container.

STEP 3

Add layers of  filter paper sand pebbles

STEP 4

Get 1 cup of dirty water in a cup 

STEP 5

Pour dirty water into the funnel 

Findings

Write a short sentence about the water every 1 minute. 

Include 'How much water has filtered through', 'How fast it is dripping through', and 'How clear the water is'.

Minutes                          1.                         2.                   3.                    4.                       5.
Drops per minute: 20
Water colour: brown water
Conclusion: The resin why that the water did not come out clean 

because that it went through it to quickly and it went out to quickly because  

the paper filter was not spreed our to the sides so the water escaped down the sides. 

The stones /sand  was not compressed tightly so the water come out through the funnel 

and in the container to quickly
