Disgusting Brown Water! (Science)

                                Disgusting Brown Water!

                                             (Dirty Water experiment)

For Science this afternoon we were finally in the lab! We did an experiment! Our first one in the lab in fact. The experiment was called "Dirty Water experiment". It was where we had to filter out the brown and disgusting water into clean water. 

Today was all about "Filtration"

Filtration means to filter something.

Here are some examples of things that filter stuff
1. Kidney
2. Tea bags
3. Swimming pool

Want to do the experiment we did?

Here is what you will need..

1. A plastic bottle (A type that you can cut into).
2. Sand
3. Pebbles
4. Dirty water
5. Filter Paper 
6. Scissors 
7. A cup
8. Craft Scissors   
---------------------------------------------------------------------------------

1. Cut the bottle with a craft knife.
2. Put the top half upside down into the bottom half of the bottle.
3. Add layers of filter paper inside the top half of the bottle, (Filter paper should be folded in quarters. When folded unfold to make a cone shape).
4. Get 1 cup of sand and put it in through the filter paper (make sure it doesn't fall to the bottom!)
5. Now 1 cup of pebbles and put them on top the sand. 
6. Now get 1 cup of dirty water 
7. Put the dirty water in the bottle
8. Make sure the water is coming out slowly!

Some helpful tips to make the outcome better! 

 1. Fold the filter paper 2-3 times for clearer water

2. When its time to put the sand in put the sand in the folded filter paper and push it down to make the water clearer.

This is our groups final product! Our water was the clearest out of all the groups.
