Dirty Water Experiment.

 Dirty Water

Aim: Separate the dirt from the clean water at the end of the experiment.

Method: 

1. Use a 250mL beaker to get 200mL of water.

2. Add 2 spoonfuls of dirt.

3. Add 10ml of oil.

4. Add a spoonful of pebbles.

5. stir it for 2mins.

6. label a piece of paper with your names and place it under your beaker.

7. take a photo of your experiment.

Experiment now:

We diluted the dirty water by stirring it together then replacing the original 100ml of dirty water twice then stirring it once again. The way we set the filter is by starting off with the base then the retort stands then putting 2 funnels, one with cloth and one with filter paper. We made this experiment by using solute substances such as dirt and pebbles then adding them into a solvent substance called water with oil. thus the solution we created was called dirty water. Then after mixing for a while some of the solute substance had dissolved into the solvent.

In our first experiment, half of our solvent substance was spilled since one of our classmates decided to run into me and spilled half of it which made our experiment concentrated. Then we added more water which made our dirty water more diluted, something I realized from this is that a change of dilution affects the outcome of the experiment.

After a brief time, we had to filter our dirty water back to clean and clear water. We used two different funnels and two different papers, the top was just a normal daily item that you buy from stores, on the bottom funnel we used a real filter paper. The top funnel was for collecting the big pieces of solute and the bottom was to make the water clear and collect the minute piece of solute and make the solvent/liquid back to how it was before we added any solute. At the end of our experiment, we managed to make it a bit cleaner than before but there was still a tint of yellow.
