Dirty water experiment

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

Examples are:

1. Water jug
2. Pools
3. Water pump
4. Fish tank

Materials

1. Bottle

2. Scissors 

3. Filter paper

4. Sand

5. Pebbles/little stones

6. Dirty water

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

Step 1

Cut the bottle at the bottom of the sticker creating a funnel.

Step 2

Put the funnel into the container.

STEP 3

Fold a piece of filter paper and put it in the bottom of the bottle neck.

STEP 4

 Add a layer of sand into the filter paper and gently pat it down.

STEP 5

Add pebbles then gently blow it so there is no dust in there and pat it so it is smooth.

STEP 6

Pour dirty water and poor into the bottle and wait for it to be all out of it and then repeat 3-5 times.

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'.

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.

this is what it will look like
