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.

Giovanna's Oil and Water Trail 3 Procedure/Data/Observations and Calculations

**Calculations:** 96/4=24/2=12 We have 12 days of water Giovanna

Ally Meyerowitz, Jannah Ramadan, Kelsey Hehir, Giorgi Irizarry =Introduction:= -Our goal for the water sample is to remove the dirt/substances from the water by using charcoal. -We think that since charcoal works as a filter, the dirt will be removed and clearing the water. -We plan to mix charcoal with the dirty water and to filter it through a funnel and filter paper. =Process:= Steps- 1) Mix charcoal with the dirty water to remove bad substances. 2) Place the funnel on top of an empty beaker. 3) Fold the filter paper at the diameter and keep making little folds around it's radius. 4) Put the filter paper in the funnel with the center of the paper on top of the opening of the funnel-tube. 5) Pour the charcoal into the filter paper without overflowing it. 6) Give it time to filter through and your result should be from black water to clear. Observations- Charcoal stays in the filter paper, but the water leaks through. The result of the water was 71 mL.

=Calculations:= Procedure- Charcoal filtering Approx. Time- 2 hrs Initial volume- 90 mL Observations before procedure- Charcoal is a solid, the Control(water) is a liquid. Final volume- 71 mL Observations after procedure- The charcoal dissolved into the water turning it black. The filter paper filtered out the charcoal and dirt leaving the water to be clear. Percent yield = (beginning volume / final volume) x 100 Percent yield = 90 / 71 x 100 Percent yield = 126.76 =**Discussion:**= -Our goal for trial 3 was to filer out the dirt 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 all of the dirt from the water using charcoal to just have clear water. It was successful. -We didn't have any error in our procedures. Our yield is 100% because we don't have any oil. or any dirt or any gravel in the water now. We just have plain cleared water.

In conclusion the hypothesis was correct. The hypothesis was to put the charcoal into the water to filter it, that will clean out all of the dirt. All that is left is salt and water, so therefore our hypothesis was correct.
 * Conclusion **

Tyler, Joey, Brendan, Dan Trial 3 lab report

Hypothesis : putting the water through the filter paper will get rid of the dirt.

Procedure: Place filter paper in funnel Flask sits under funnel to collect the water The filter paper will collect the sand and some dirt

Eqiupment: Filter Paper, Erlenmeyer flask, Funnel, Dirty water.

Data: poured 47 mL of water through the filter paper and we came out with 46 mL. It took 11:14:25 for all of the water to filter through

Conclusion: The filter paper caused the dirt to separate from the water. Therefore the hypothesis was correct and the water was cleansed of the dirt.

VermiglioCassaKralHehir Trial 3 Intro:Our goal is to purify the water sample. We assume that there is mud and oil in the water. We will run the water through the rubber tubing and the pinch clamp in hopes to separate the water from the oil.

Procedure/observations: All the oil stayed at the top of the funnel.

calculations:
 * procedure || approx time || initial volume || observations from before || Final Volume || observations after ||
 * funnel || 3min 8sec ||  || oil moved up to the top ||   || oil and dirt split ||

Discussion: So we questioned if it would work to put all the water and oil in a funnel and use the pinch clamp to separate the water to the oil. And it had worked. We put all of the water and oil in the funnel, then pinched the pinch clamp, and the oil came through. So we pinched the clamp, and the dirty water was left in the funnel.

Conclusion: After putting a clamp on the rubber tube, the water that was going to go through it stopped. Then the water went through as the oil stayed on the top. There is still some oil in the water but that would be okay to boil out.

__**TRIAL #3**__
**-We didn't have any error in our procedures. Our yield is 100% because we don'thave any oil. or any dirt or any gravel in the water now. We just have plaincleared water.**
 * Introduction#3: **
 * Now we are going to use the ash from the fire (Charcoal) to filter the water. The charcoal is going to filter out the smell from the water and it is going to clean out some of the germs. We are going to mix it and then use the filter paper and a funnel to then take out the charcoal. **

SESSA, SCALIA, GARCIA, HENDERSON LAB 3 Purifying Water

Purpose- To separate the water from the oil.

Materials- Glass Funnel, Rubber Tubing, 1 Beaker, A Pinch Clamp, clay triangle, ring stand, iron ring. We will have the funnel attached to the rubber tubing and the pinch clamp attached to the tubing so we will be in control of how much water goes through the tube. we will pour the swamp water into the funnel, let the oil and water separate soo the oil is ontop then drain the water out and leave the oil in the funnel.

Data and Discussion- In the attempt today we were successful with spliting the oil and the water. it was a success, there is sum oil left in the water but not enough to take anymore out.

Conclusion: In conclusion removing the oil from the water was a success. In out next attempt we will be completely purifying the water. but today we did remove the oil. we soon will be able to drink the swamp water, with a few more tests. Our first to failures lead us to todays success, and we hope to have more.

__trial A__ started at 47 ml finished off as 50 ml  __trial B__ it started out at 27 ml and it went to 25ml

Purpose- make the water clear and clean

Materials- Glass Funnel, Rubber Tubing, 1 Beaker, A Pinch Clamp, clay triangle, ring stand, iron ring.

Data and Discussion- we used a small beaker and put charcoal into it with the dirty water then we mixed it for 5 min after that we filtured the water/charcoal one last time and the water was clear

Conclusion: In conclusion we were able to clear the water and make it clean, The last step we have to do is probably boil it to make sure it is healthy and clean enough to drink from

__Trial C__
 * Tocci, Pilli, Kroner, Kerrigan, Shields**

Purpose:

The purpose of this lab is to purify the water from the ponde on the Island our plane crashed on. We must purify the water so that we may drink it and survive on this Island until we are rescued. Materials and Mehtods: Rubber Tubing Graduated Cylindar Glass Funnel Pinch Clamp Beaker Conclusion: The dirty water had no solids left in it and most of the oil was removed. This trial was a success that worked and if needed to purify more water we will use this to do so.

Trial 3: kalb Hypothesis: We put some pebbles in the funnel which is connected to the rubber tubing, we are using the pinch clam to regulate how much of the murky water goes through, we let the oil settle and then released some of the water.

1)conected the funnel to the rubber toobing and placed the pinch clamp under the funnel. 2) we then put rocks in the funnel and then poored the water in it 3) the water did not seperate from the oil

Conclusion: This idea failed the oil still stayed in the water.
