Trial 1:

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. Observation- The flitter paper did not take the oil out of it the oil went threw the flitter paper and didn't really do anything. Also the paper took out the big stuff from it like big dirt particles and things like that. 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



Trail 2: Question: Can we filter our murky water by using the materials we have from the wreckage? 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. Observations: The rock and sand in the Styrofoam cup method failed to remove the oil but did remove large particles from the water.

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 Analysis: The oil still stayed in the water, but this experiment removed the larger particles in the water. Conclusion: this hypothesis is failed because the oil still stayed in the water, but this experiment is partially true because it removed the larger particles in the water.



Trial 3: purpose: To clear the dirty water Material: flourence flask, rubber tubing, funnel, pinch clamp 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. Discussion: The water was still dirty and not clean Data: 1)connected 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.



Trial 4: introduction: Will this method clear the dirty water and make it clean. 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. Then, we use 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. We are basically just combining Trials 2 & 3. purpose: to clean the dirty water and make it clear. 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) Connected the funnel to the rubber tubing and placed the pinch clamp under the funnel 7) We then poured the water in it 8) The water began to separate Discussion: The water was coming out without oil until the rubber tubing got clogged with dirt. Conclusion: This did not work and the water was still dirty.

Trial 5: Introduction: We are hoping that filtering the water from trial 4 will leave us with clean water Hypothesis: After we completed step 4, we take the water and run it through the filter paper, this removes the small particles from it. 1.Complete Trial 4 2.Put filter paper in funnel 3.Pour water though and let filter Discussion: The water was cleared of particles but was left only with a greenish tint Conclusion: The hypothesis was partially true but failed because the water has a green tint and is questionable to drink

Trial 6: pic with charcoal mixed in Introduction: We are hoping that the charcoal will remove the color and smell of the water. Hypothesis: We take water from Trial 5 and mix with charcoal. Then run the charcoal/water mix through filter paper. The purpose of the charcoal removes the odor from the water as well as removes the coloration.

Discussion: After mixing the charcoal and water it became black water but after filtering it again it was clear and had no odor. Conclusion: The hypothesis was successful because the charcoal did remove the coloration and odor from the water. __Notes After Trial 6:__ We measured the clean water we have. We have 36 milliliters of clean water which equalled 36% yield.
 * 1) Complete Trial 5
 * 2) Mix about 5 milliliters of charcoal with the water
 * 3) Run the charcoal/water mix through filter

Trial 7: pic of boiled water Introduction: All that we need to do with our clean water is to boil it to remove any salt and kill bacteria. Hypothesis: After we test the water for ions (salt) We are going to boil our water to remove salt and kill any bacteria present, we will use a Erlenmeyer Flask to boil it because the neck is smaller and we wont lose as much water.

Discussion: We boiled the water and it was ready to drink. Conclusion: Our final trials made success and we will now survive.
 * 1) Plug light bulb in and dip rods into water, if light turns on, salt is present
 * 2) Put water in erlenmeyer flask and use a ring stand, ring clamp, and a Clay Triangle to suspend it over the bunsen burner.
 * 3) Boil the water
