On the 22/2/19 we did a filtration experiment.

The experiment:
Can we filter dirty water with a number of substances?

Equipment:
Funnel
Chronicle flask
Small rocks
Saw dust
Cotton balls
filter paper
Dirty water

Method:
We got the rocks and put them in to the funnel then poured the dirty water into it which the rocks helped get the big clumps of dirt out.
We then put saw dust into a different funnel which helped get some of the dirty colours out of the water. Then we put a few cotton ball into the filter and poured the water into the funnel which helped get the water a bit clearer. Finally we put out filter paper which got it clearer then it started. I think we could of gotten the water even clearer if we tried a different technique.
