Dirty Water Experiment

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.  Tea bag
2.  Coffee Grinder
3.  Water Jug
4. Pool filter

Materials

1.1.5l plastic bottle
2.Filter paper
3.Sand
4.Cup
5.Gravel
6.Dirty Water
7.Scissors
8.Craft Knife
Process - ( use verbs or doing words in each step )
Step 1 Cut the bottle into half with the craft knife and scissors.
Step 2 Put the funnel in the container. 

Step 3 Fold the filter paper in 4 like a cone.

Step 4 Place the cone in the funnel.

 Step 5 Add layers sand in to the filter paper then add the gravel to the mix.
Step 6 Get 1 cup of dirty water then add it to the mix

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'.

1. First it came out pretty dirty at first
2. It only got slightly got cleaner 
3. then it has just stayed like that 
4.

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