Trial 1 Intro: Goal: to make the water pure What is in the water: oil,dirt salt Plan: let the water settle and extract the water.

Procedure: Steps: 1. Settle the oil in the funnel, held up by a ring stand and clamp, that was connected to a rubber tube. Then use the clamp as a strainer and let it go slowly. 2. Strain it in the valve Volume- Before 20 ml After 17 ml Before 50 After 38 Time: 8 mins for 17 mls * mins for 38 mls __Calculations__ · 80%   · 20% impurity removed __Discussion__ · Our goals for the filter paper was to be able to filter everything out of the water. · Then with the oil removed we could boil it to remove all bacteria. Sadly with the filter paper we could not remove the oil so there for we could not boil it to remove the bacteria. Conclusions- We have found great success in what we have tried to accomplish, with purifying foul water. The way that we were successful was that we got a funnel and rubber tubing and a pinch clamp. We put the pinch clamp on the rube and the tube on the funnel and purified water is going to come out not right away but sure enough water would come out clean. We had the right idea the first couple of times but we didn’t do it but our last try was the most important and we did get it to work. My group was very good and except for one thing. But other than that we had a very good group.

Trial 2 Intro: Goal: To make the water pure What is in the water: dirt and salt Plan: Filter the water

Procedure: 3. filter the water a funnel with filter paper in it which drained into a flask. We took 57mls away and got 52mls in 13 minutes 4.filter the water with wood ash in a piece of filter paper in a funnel which d rained into a beaker. before 52 after 39 **__Calculations__** · 63.2%   · 36.8% impurity removed **__Discussion__** · First we use a funnel, some black tubing, and a pinch clamp to create a separator funnel. · Our goal was to drain the water from the oil by using the pinch clamp as a valve. · We successfully drained most of the waster from the oil. · All we need to do next is filter out the solids.

Conclusion- To get the water purified we used ash in the filter paper we had, the ash helped clean the water change e color and take away the smell. In general the group worked great all around except for some exceptions with being absent. Our group found out that we could work really well when we put all our heads together. This trial we really completed what we needed to do we just needed to boil it next. This group experience was great.

Trial 3

Intro: Goal: to make the water pure What is in the water: salt Plan: boil the water

Procedure: 5.boil the water. Before 39 After 35.1 Calculations · 90%   Discussion · Our Goal for boiling the water was to remove the salt. · We boiled the water sent it through a cold tube and caught it in a flask removing the water from the salt. Conclusion- This trial we handed our water to Mr. Erickson to boil the water in the distillation. It worked our water is so clean and know we know that we can survive on this island for a long time. This was probably the simplest trial out of all of them. Our group worked so good through out this whole experience.
