Filtering Experiment

W.A.L.T. remove insoluble particles from dirty water by filtering

What we used: APPARATUS
filter paper, a funnel, dirty water, a beaker

What we did: METHOD
1. We folded the filter paper in quarters.
2. We placed the filter paper in the funnel.
3. We placed the funnel in the beaker.
4. We carefully and slowly poured the dirty water into the filter paper.
5. We waited.

What happened: RESULT
Seemingly cleaner water trickled though the funnel into the beaker. Insoluble particles remained in the filter paper.

What we learnt: CONCLUSION
By filtering water, we removed insoluble particles from dirty water but we learnt that filtering does not remove bacteria.
