Dirty Water Experiment

Aim: To make a filtration plant using household materials.

What is filtration?

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

Examples are:

1.  Tea bag
2.  Water filter
3.  Coffee filter
4. Aquarium filter

Materials

1. Rocks

2. Pop bottom top

3. Coarse sand

4. Fine Sand

5. Coffee filterer

6. Elastic sand

7. Pop bottle bottom

8. Dirty Water

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

Step 1

Cut the bottle in half.

Step 2

Put the top half upside down.

STEP 3

Add layers of rocks, coarse sand and fine sand.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour dirty water into the bottle and it should start to filter.

STEP 6

Observe how the water flows. 

Measurements

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'.

There was a decent amount of water that filtered through, it dripped pretty fast.  But it wasn't clear as I thought, although it was a really successful and a fun experiment to do. 

Warning

Make sure that an adult cuts the bottle in half. This water filter is just an experiment and should not be used for drinking water.

Avoid using charcoal briquets, as these can contain chemicals you don't want in your water. Use the activated carbon for water purifiers instead.
