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.

====Lab Data Trial 1 Introduction For the experiment of purifying or cleaning dirty water we put a hole in the bottom of the cup and placed filter paper at the bottom covering the hole. On top of the filter in the cup we placed small rocks and sand on top of the rocks. The water will go through a funnel making it drip it into the through the sand and rocks leaving things within the water behind and then to boil it. Procedure- - Put hole in bottom of cup and place filter paper inside covering the hole - Place small rocks and sand on top of the rocks - Place funnel on top of the flask with the cup on it so the water can drip through - Pour dirty water into the cup and wait for all the water to drip through into flask - When done, the water had appeared a lot more clear than it did when poured - Lastly, to boil the water Equipment- -Sand, small rocks -Funnel, Erlenmeyer flask -Small cup, filter paper This time we put the sand and rocks on top separately looking for a difference in the water.====

=**How To Purify the Water**=

**Introduction:**
The Hypothesis is to remove the oil from the water by using a funnel, beaker, rubber tube, and a pinch clamp and to remove the oil from the water. First, let the 25 mL water sit in the beaker until the oil to rises to the top. Then, take rubber tubing and attach to the bottom of the funnel, pour the water into the funnel. After, use two pinch clamps and attach to the middle of the tube and finally, slowly release the pinch clamp and let out the water gradually, and then keep the oil at the top of the tube. Before it goes into the water. Then at the end you have water that’s been separated from the oil.

**Process:**
Steps- 1) Let the 25 mL water sit in the beaker until the oil rises to the top. 2) Take rubber tubing and attach to the bottom of the funnel,pour the water into the funnel. 3) Use two pinch clamps and attach it to the middle of the tube. 4) Slowly release the pinch clamp and let out the water gradually; keep the oil at the top of the tube before it goes into the water. 100 mL given, 25 mL used in this trial. The result is 20 mL.

Calculations:
Procedure- Oil Separation Approx. Time- 2hrs Initial Volume- 25 mL Observations before procedure- Oil floats to the top. It does not dissolve into the water. Final Volume- 20 Observations after procedure- The particles are on the bottom of the foul water. Oil is separated. Percent Yield = (beginning volume / final volume) x 100 Percent Yield = 25 / 20 x 100 Percent Yield = 125

After-


=**Discussion:**=

=
-No we did not change anything because what we originally had planned had worked the first time. Yes were satisfied because we tried what our hypothesis was and it worked out.=====

=
-We didn't have any error in our procedures. But our yeid is not supposed to be 100% yet because we have not completed all of our trials, so therefore the final result is not yet reached.=====

= Conclusion: = The hypothesis was to use a funnel, beaker, rubber tube, and a pinch clamp to remove the oil from the water. The hypothesis was correct.In this experiment we used 25 mL and ended up with 20 mL of water. We let the water stay overnight to make sure it settled and that the oil raised to the top. Since the experiment was successful we purified a total of 100 mL of water and ended up with 95 mL.

 * 1.) Introduction:** **Our goal for our water sample, is to try to figure out how to separate oil from water. I think that the water is distilled water and that even though the oil lays on top of the water, there is some oil on the bottom of the bottle that is mixed in with the water. Some experiments that my group planned to perform based on our hypothesis, were, that we put about five or six rocks into the graduated cylinder, and poured some of the oil/water into the graduated cylinder, but nothing happened. My group also tried to put some of the oil/water into the sand, but nothing happened.** **Paige**


 * 2.) Procedure/Data/Observations/**
 * - What you need: Flask, Funnel, Filter paper**
 * - 1.Filter paper into funnel with rocks**
 * 2. Pour water mixture slowly into funnel and wait.**
 * -About 5 mL into the funnel and about 2 mL came out**
 * -It took about 54 seconds for all of the the dirty water to come out of the funnel**
 * -Removed almost of all the solids from the solids but there could still be oil mixed with the water.** Giovanna

**3.) Calculations: After the two tries, we have not been able to come to a conclusion of much water was purified.** **ZORN**

**﻿** 4.) **Discussion:** **1. Our goal for each step, was to try to separate the oil from the water. We hoped to remove the oil from the water. Every experiment that we tried to do so far, failed.**

**My group changed some procedures, because when the procedures that we tried didn't work, we came up with another way that would maybe work. We added procedures, because my group wanted to see what experiments would work for us. I am satisfied that this was the right thing to do, because some of the experiments that my group tried didn't work for us. The right thing to do, is to try to figure out how to do the experiment.**

**The impurities that we removed from the water, was the oil.**

**Our yield is not and should not be expected to be 100% because we won't be able to get all of the oil out of the water.** **Shayna**


 * 5.) Conclusion: -So far we haven't had much success in purifying our water. We have been coming up with new ideas everyday and trying them.**
 * -A few changes that we probably would have made now to our procedure if understanding the situation and knowing details that we didn't know now we probably would have stopped and read over a few more times what supplies we are given and basically just try to get more than one "experiment" done in the matter of one period. Because now we are taking up the whole period thinking of new ideas and it takes up way to much time and by the end of the period we only completed one experiment.**
 * -So far our overall experience as a group in performing this activity would be very good. We are working together and communicating well; plus everyone basically has an input one everything we do.** SHAYNA

__VermiglioCassaKralHehir Trial 1__ Foul Water Activity

Introduction
 * Our goal is to purify the water sample.
 * We assume that there is mud and oil in the water.
 * We plan to run the water through a cup filled with rocks in order to purify it.

Procedure/ Observations 1.) Fill a cup with rocks on the bottom and sand on the top. 2.) Poke a few holes in the bottom of the cup. 3.) Take the dirty water and pour it through the cup with sand and rocks.

· The water was absorbed by the sand. · There was too much sand.

Calculations:


 * procedure || approx. time || initial volume(ml) || observations before procedure || Final volume (ml) || observations after procedure ||
 * trial 1 || 14sec. 46ms ||  || plastic cup filled with rocks, holes were cut in the bottom of it ||   || some water came out of the cup into the beaker, but it was not filtered out and purified ||
 * trial 2 || 0 ||  || plastic cup with sand and rocks in it ||   || no water came out of the cup into the beaker ||

384 cups 2 cups per day 4 people 4 other people took ¾ cups of water with them 384 / ¾= 288 384-288=96 cups in total 96 / 4people = 24 24/2cups=12 12/2= 6cups per day per person

Discussion: We questioned if it was a good idea to poke holes in the cup and then the rocks would have stopped the clumps from coming through. But when we tried it, we made the mistake of poking too many holes, and it didn't work. The holes were too big and too many and the water went right through. so the water wasn't clean, and it went right through. So then we questioned if it was a good idea to try sand and rocks, and when we tried, nothing came out. There was too much sand in the cup, so we have to find another solution.

Conclusion: With using the sand, the dirty water did not make it through and just was absorbed in the sand. we tried to use rocks also but that did not work because the water went straight through the rocks and nothing decided to clean the water. If we didn't use as much sand, our water would have flowed through it better and would have maybe not have got stuck in the sand.

Adam,Abo-ela,Del Villar,pallatta Question; how do you clean the water and make it pure to drink? 1. Introduction Our ideas for what is in the water is what follows
 * The goal for our water sample is to clean the water to the point that we can drink it
 * turf [dirt]
 * sulfur
 * water
 * oil
 * garlic
 * Hypothesis : yes the solids can be separated by using the filter paper


 * We are planning on separating the solids and liquids and from there we are going to take the proper steps to clean the water.

2.


 * This is what we intend on doing when we get to experiment:

1st: fold filter paper over the cup 2nd: pour it into 3rd: get rid of the solids

The water is like a fish tank because: 1. The gravel traps lose partials at the bottom

we will cut little wholes[pencil size] with a sharpened pencil then… we will put the liquids into a cup with sand and pebbles on the bottom, from there that will again stain the clean water from the bad liquid.

3. Calculations:
 * we started off with 100 ml then we ended up with 35 ml. we didn't use all of the water given so we can save it for more experiments.
 * Also we noticed that the odor was reduced by a lot to the point where can you smell it without getting sick.

4. Discussion: Our goal is to be able to purify the water within the first try of the experiment, without any problems
 * Success
 * __Failure__
 * We realized that it is a good start to the experiment because we were able to solve what we hypothesized that we could separate the solids and the liquids. Other groups didn't do that all they did was get rid of the oil.
 * The solutions we got rid of was the solids. To us it looked like dirt or something to that extent.
 * We didn't get through all the steps of clearing our water, so we do not know yet whether or not we will be able to purify it to 100% yet.

5. Conclusion:
 * We are not able to able to conclude this information at this time because we have not attempted to purify all the water at this time.

Introduction: The goal of this lab is to make the water as pure as possible. You should be able to drink the water. The water should not get you sick. We thought that there is sulfur, oil and other molecules in the water. We planned to drain out all of the solids and oils from the water. We also thought of draining out all of the bad water, making the water easier to clean.

Procedure/Data/Observations: (normally //Methods/Materials// is a separate section) · Document the steps and equipment you use to purify your water in the order that they are preformed · Data- volumes before and after each step of your purification · Observations of your initial and final samples of water as well as any intermediate products (what you keep and what you remove) · Pictures of setup before, during, and after

1. pour the liquid into the water bottle 2. put the funnel paper in the flask and the filter paper in the funnel. 3. pour the water from the water bottle into the funnel (started at 2:23: took three minutes) 4. then pour more in, you must do it periodically because it takes long (took three more minutes from 2:36) EQUIPTMENT: funnel, filter paper, beaker, dirty water

Volume before: 90mm after: 50mm

final water: got the solids out, but doesn’t filter the water and oil

Calculations: Dirty water we started with: 10 ml Fliter water (first attemped to clean): 5ml Dirty water still left to experiment on: 6.5 ml

Discussion: *The method we used to eliminate the solids and the oils from the liquids was we would first put filter paper into the glass funnel like a coffee filter. Second we poured 6.5 ml of the dirty water into the funnel. Next, the water would drip through the paper and into the Erlenmeyer flask. We were hoping that the oils would be left behind. However, the oils managed to get through it which mean we cannot boil this water. Also, most of the dirt solids did not come through the paper. We are still not satisfied about oils still being in the water so we need to figure out another way to purify it.
 * Our goal was to purify the water as best we could. We hoped we could get all of the oils and solids out of the water but the filter paper didn’t quite do the job. I would say it got half of the oils out.

5) Conclusion · The group didn’t completely purify the water, but we did partially. The funnel and filter paper got rid of the solids, although it failed to separate the oil and the water. · To make the experiment completely successful we should have thought about getting the oil separated too. Although, while doing the experiment we still believed that the oil would separate from the water, but it didn’t. · As a group we worked well and finished everything by the end of the period. We were all helping and doing something in during this trial.

Scalia Sessa Henderson Garcia. Purpose – Is it possible to filter out water from oil?

Questions – How are we going to purify water? Method- we used the filter paper in the funnel to try to filter out the oil from the water.

Steps – First we get the dirty water and filter paper. We use the filter paper to filter the oil out of water.

Conclusion – The filter paper took much longer then we thought. It went drip by drip. And let oil in. It did not work.

Week 1: kalb

Question- is it possible to separate from water with 1- 100mL graduated cylinder, 1- 150 mL beaker ,1 glass funnel, 1 pinch clamp, 1 styrofoam cup, filter paper 1- 150, ml Erlenmeyer flask, rubber tubing and sand, gravel, charcoal and fire from the island. Hypothesis- in order to separate oil from water and dirt from the swamp water take flitter paper and poor the mixture into it to take that water out.

Analyzing- The flitter paper did not take the oil out of the water it just dissolved threw the paper but did take away any dirt that was in the water. Conclusion- It is partly true because there was no dirt in the water after it went threw the flitter paper but the oil did not stay on the top like we hoped it would.
 * 1) take 25 mL of water and poor it in to a Beaker with flitter paper over it.
 * 2) Let it sit and let the water drip into the beaker
 * 3) The water wait a while for the water to drip into the breaker
 * 4) once done take the breaker and boil the water.
 * 5) Should be ready to drink
