Hurumanu - Dirty Water experiment

Home Chemistry: Dirty Water Expierement

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.  Air Filtration 
2.  Oil Filtration (Car)
3.  Pool Filtration 
4. Water Filtration 

Materials

1. Funnel 

2.Container

3. Filter

4. Pebbles

5. Dirty Water

6. Fine Sand 

7. Cup

8. Scissors

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

Step 1

Cut the bottle in half.

Step 2

Put the top half upside down on the bottom half, then put in filter paper. 

STEP 3

Add layers of fine sand and pebbles.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour the dirty water into the top half.

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: 60 drops
Watercolour: Light Yellow
Conclusion: When we first started our didn't work because we poured the water ib too fast. So we had to start again but this time we put the sand and the pebbles in carefully especially the pebbles so the water doesn't go in the sides. We waited for a bit more but the water turned out to be quite yellow-ish. After that, we again grabbed some filter paper to make the water clearer. So we did it again and water was clear but still quite yellow-ish. Overall I really liked this experiment.
