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 2

**Title:** How to purify toxic water. Hypothesis: When we let the oil and water separate, the water can be let out the bottom stopping it on time so that you only left with oil and the water separately. **Materials:** Ring Stand, a funnel, a piece of rubber tubing, stopper and a beaker. **Procedure.** We will first let the water and oil separate and then we will send it down a rubber tube with a stopper. You then will let the water out but stop right before the oil goes down the tube. **Data:** After pouring 50mL of dirty water through our set up and we got about 90% of the oil out. And now we have 47mL of liquid. **Conclusion:** In the end I believe that our procedure was a success. We overall got out most of the oil and I believe if I go through the experiment another time I eventually can get all of the oil out.

Ally Meyerowitz, Kelsey Hehir, Jannah Ramadan, Giorgi Irizarry- We started with 95 mL and ended up with 90 mL. We let the water filter over night. Started at a quarter to 3.
 * Introduction:** Our plan is to use a funnel, filter paper, ceramic triangle, and beaker to remove the dirt from the water.

Steps- 1) Place a funnel through the ceramic triangle into the beaker. 2) Fold the filter paper like a fan and place the core of the fan in the opening of the funnel. 3) Pour the dirty water into the filter paper. Volume before- 95 mL Volume after- 90 mL Observations- The solid dirt was removed during this process, however it is not clear or completely purified.
 * Process**



Procedure- Dirt Removal Approx. TIme- 2 hrs Initial volume- 95 mL Observations before procedure- Dirt is a solid and solids can't be absorbed. Final Volume- 90 mL Observations after procedure- The dirt stayed in the filter paper while the dirty water ended up in the beaker. Percent yield = (beginning volume / final volume) x 100 Percent yield = 95 / 90 x 100 Percent yield = 105.55
 * Calculations:**

-Our goal for trial 2 was to separate the dirt and some gravel from the water. It was successful. -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 removed the dirt and some gravel from the water hoping to just have plain water with no dirt or gravel. It was successful. -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.
 * Discussion:**

The hypothesis was to use a funnel, filter paper, ceramic triangle, and beaker to remove the dirt from the water. The hypothesis was correct and we had just plain water with no dirt or anything in it. For this trial we removed the dirt from 95 mL of water. We let the water stay over night so that we could get all off the dirt and whatever else was in there fully out of the water. In the morning we had just plain water.
 * Conclusion:**

**Carney Trembath Kasper Villani** __**TRIAL 2**__ Introduction #2: For trial two, we are going to haveto separate the material that is heavier than the water. To do so, we are goingto put filter paper inside the funnel so that when the water is poured into thefunnel, all of the solid objects stay behind. Steps- 1) Place a funnel through the ceramic triangle into the beaker. 2) Fold the filter paper like a fan and place the core of the fan in theopening of the funnel. 3) Pour the dirty water into the filter paper. Volume before- 95 mL  Volume after- 90 mL  Observations- The solid dirt was removed during this process, however it is notclear or completely purified.   2.) Procedure/Data/Observations – (Flask, Funnel, Filter paper) - 1.fan the filteraper into the funnel to catch all solids 2. Pour water mixture slowly into funnel and wait. -About 5 mL into the funnel and about 3 mL came out -It took about 58 seconds for all of the the dirty water to come out of the funnel -It removed 95 %the solids from the water Calculations: -Not fully purified Discussion#2: Discussion: Our goal is to be able to purify the water within the first try of the experiment, without any problems. 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 have separated the oil and water, and the solids and liquids. We are left with just dirty water which is almost clear and doesn't have that bad of an odor. IT can not be 100% yet because we have to figure out to clean it more. Conclusion: -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.


 * ZORN, MINUTO, CONRAD, INSERRA**

1.) 1. Our goal for our water sample, is to try to figure out how to separate oil from water.

2. 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.

3. 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


 * 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.

Our group changed our procedure because we felt that by adding the rocks it could help seperate some of the water and oil. We kept added procedures because once one of our steps wouldn't work we would have to start over from the beginning.

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

At the end of this trial we couldn't get a lot of the oil out of the water because it was so mixed together and the steps we tried were completely off. But in the end we don't think that everyones water could be 100% complete because there could always be a drop of oil in the water Shayna

5.) Conclusion: After the two tries, we have not been able to come to a conclusion of much water was purified. ** Eric **

Trial 2 VermiglioCassaKirstenHehir Introduction: Our goal is to purify the dirty water so it's clean enough to drink.

We think that there is dirt and oil in the water.

We plan to run the water through a funnel with a filter in it. It will then go through a rubber stopper and hopefully clean it.

Procedure/ Observations 1.) Filled a funnel connected to a tube 2.) Placed rocks into the funnel, then tried filter paper. 3.) Poured the dirty water into the funnel and oil came out the tube into the beaker.


 * calculations:**


 * procedure || approx time || initial volume || observations before the procedure || Final volume || observations after the procedure ||
 * rocks || 4min 40sec ||  || glass funnel filled with rocks. funnel connected to tube into beaker ||   || little to no water came out into the beaker ||
 * filter paper || 1min 20sec ||  || filter paper in funnel. funnel connecting to tube, pouring into the beaker. ||   || some oil came out into the beaker ||

discussion: We had tried to put the funnel and the rocks together, and then we wanted to see of the oil would come out by itself. But when we did it, it didn't work. it was so oily, that it got stuck into the tube. So we dumped out the rocks and tried to do filter paper and then it kind of worked. The water stayed on the top and the oil came out a little bit. So we kind of found a solution but need to work better.

Conclusion: After putting rocks in the funnel, the water went straight through and the oil did not separate from it. Next the filter paper was in the funnel and the water stayed at the top in the filter paper as the oil went through and landed in the beaker.

Scalia Garcia Henderson Sessa Purifying Water

Purpose: To filter oil from the water, using sand, charcoal, and gravel.

Question How would we be able to purify the contaminated swamp water?

Materials and Methods- Styrofoam cup, charcoal, sand, and gravel we will have the cup with a pin sized hole in the bottom of the cup. Then have different layers of sand, gravel,and charcoal to separate the oil from the water. We will pour the swamp water into the cup and in theory the oil will sit on top of the sand and gravel and the water will drain.

Data and Discussion- During the experiment the swamp water that went through the sand and gravel and funnel came out clean. the sand and gravel took out the larger of the dirt and particles leaving the oil and smaller particles in the water. Some Images are included under Lab images.

Conclusion- In summary the tests we did to remove oil from the water did not end up well. But, the sand and gravel did filter out some dirt and it might be possible to keep that in mind in later attempts. Without removing oil from the water it will be impossible to drink the swamp water. The two failures will also be a big part in later attempts, it gives knowledge of what not to do and what to do.

Adam,abo-ela, pallatta, Del Villar trial 2 Question; how do you clean the water and make it pure to drink? 1. **introduction**


 * The goal for our water sample is to clean the water to the point that we can drink it
 * Our ideas for what is in the water is what follows
 * turf [dirt] // sulfur // water//oil//garlic

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
 * 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.

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.
 * % yeild(100/35) * 100


 * 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 have separated the oil and water, and the solids and liquids. We are left with just dirty water which is almost clear and doesn't have that bad of an odor. IT can not be 100% yet because we have to figure out to clean it more.


 * 5. Conclusion:**
 * so far we have proposed 2 tests. Our success has been pretty good, because we have succeeded with all our theories so far. all we have left is yellowish water, with a not so bad odor.
 * There is nothing i would change from this point because everything we wanted to happened happened. If there was anything to change it would be how fast it took us to compete the separations for the solids and liquids.
 * We do not have a final experience with the project because we are not done yet.

Trail 2: kalb Hypothesis: put Gravel and sand into a Styrofoam cup. Then poke a hole in the bottom of the cup and place it over the beaker. Poor the water into the cup and let it drip into the beaker

1) Pored sand and rocks into cup and poke a hole in the bottom of the cup 2) Poor 25ml of water into the cup 3) The water is going through the rocks and sand and going into the beaker 4) We added 25 ml more into the cup 5) All of the large particles in the water were removed, but the oil stayed in the water and oil and water entered the beaker. 6) 20 minutes Conclusion: this hypothesis failed the oil still stayed in the water, but this experiment removed the larger particles in the water.
