Hypothesis  What will we do?  **Boiling will remove most of the elements in the water to make the**  **swamp pure. We figured out that this will cause an explosion.**  **First we are going to filter out the water until it becomes pure.**  Why are we doing it?  **We are doing this to get all the dirt out of the water so filtering**  **will help with this.**

9-22-10 ** Our group discussed how much water we need to survive today. We did ** ** some research and this is what we got. The warmer the temperature the ** ** greater your warmer consumption needs to be. Human beings can survive ** ** about three to seven days without the intake of water depending on the ** ** climate. Each person in our group has 8 bottles of water which is four ** ** liters per person. Therefore, with the water we have, we would be able ** ** to survive a little over 11 days. (11.08 exactly) We set up a ** ** proportion using this website. It said we needed 3.79 liters of water ** <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">** to survive 10.5 days. We put 3.79 over 10.5 times 4 over x and got ** <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">** 11.08. We used this website that had a table to help us get our ** <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">** answer, http://www.survivaltopics.com/survival/how-long-can-you-survive-witho.... **

Hypothesis - Since this is our first attempt, filtering the water with charcoal, gravel, and sand will get the dirt out of it.
 * Journal 1, Experiment 1, Day 1 **

<span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;">1. Put filter paper into funnel <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;"> 2. Place charcoal into filter <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;"> 3. Connected funnel to one end of the black tube <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;"> 4. Put gravel on top of charcoal <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;"> 5. Placed other end of black tube into graduated cylinder and poured swamp water down <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;"> 6. Added sand to the filter <span style="font-family: tahoma,arial,'nimbus sans l',sans-serif; font-size: small; line-height: normal;">We are using this procedure to filter all the disgusting particles, sand, and dirt out of the swampy water. Once we get all this out we are going to filter it out more and more to get clear water.

This is a picture of our materials we are using. As you can see in the beaker there are two layers and that would make it a heterozygous mixture. The top is bubbly and the bottom is dark and full with dirt. If we started boiling this swampy water, it would explode. Our result wasn't as accurate as we thought it would be so we decided to filter again tomorrow.

Hypothesis- <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;"> If we filter the water using sand, gravel and charcoal then all the dirt and oil will filter out so we can get a clear, pure substance. We are using this procedure so we can get a more purified water to work with. We know that if we keep filtering it the water will become clearer. That's basically what we decided to do for each experiment until the water becomes a pure element.
 * <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">Journal 2, Experiment 2, Day 2 **
 * 1) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">Added 10mL of sand
 * 2) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">25mL of gravel
 * 3) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">5mL of sand
 * 4) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">2mL of charcoal
 * 5) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">5mL of sand
 * 6) <span style="font-family: arial,sans-serif; font-size: 12px; line-height: normal;">Added 100mL of water into the funnel.


 * Water after our second attempt**- We were happy with our results because it became homozygous and is now easier to make pure. Now that we know that filtering is the best way to get purified water, we decided to filter again and again to see if the water can get any clearer. Now we are trying to get the color out of the water.



Hypothesis- If we filter again but only with sand and charcoal then the water will become clearer.
 * Journal 3, Experiment 3, Day 2**

The water got a little clearer after that. 3. We sprinkled some more sand into the filter. We decided to filter again to get clearer water but this time only with sand and charcoal. This seemed to really work so we can separate the oil.
 * 1) Filtered 30mL of sand
 * 2) A pinch of charcoal


 * Water after our third attempt-** This worked really well because the water became clearer in color. We are going to keep filtering to see what happens.

Hypothesis- Since in experiment two the sand made the water a lot clearer, we decided to filter the water with just sand because the water still has some oils in it.
 * Journal 4, Experiment 4, Day 2**

The water started looking really sandy and dirty so this experiment didn't work. We decided to filter it again with nothing in it so we could get the sand out. We started with 60 mL of water now we only have 30mL.
 * 1) Put 20mL of sand
 * 2) Added 10 more mL of sand


 * Water after our fourth attempt**- This didn't really work out because all the sand that we tried filtering with the water got into the water and made it dirty. The sand also sucked all the water in so we don't have a lot of water left. We know now not to filter with just sand because it just makes the water dirtier than it already is and we need it to be perfectly clear and pure.

Hypothesis- If we add some charcoal with the sand, then the charcoal will help filter out the oils and the color of the water.
 * Journal 5, Experiment 5, Day 2**

The water now looks cloudy but is looking very accurate. We need to separate the oils so we are going to filter again.
 * 1) 20mL of sand and a pinch of charcoal.


 * Water after our fifth attempt-** We attempted to purify the water again to make it clearer.



Hypothesis- Filtering the water continually will eventually remove the remaining substances in the water.
 * Journal 6, Experiment 6, Day 3**

Today we didn't get anything done. We tried filtering more water with the original swampy water but we ended up with nothing. We talked about what we're going to do and we decided to keep working with the 22mL of water we have that's somewhat clear, but very cloudy. Tonight we decided to think about what we could do to get back on track.

Hypothesis- Since our water is still cloudy, filtering will make it at its clearest.
 * Journal 7, Experiment 7, Day 4**

Our experiment worked very well because we decided that the charcoal will take the color out of the water. We calculated the volume of our water and it's 23mL. We did this by pouring the water in the graduated cylinder.
 * 1) Filtered with charcoal to make the color become clearer

We calculated the density of our water and it's 22.6g/mL. We subtracted 135.2 and 157.8. This was when we calculated the density. By calculating the volume we just poured the water in the graduated cylinder. Now that we finally have pure water we still need to boil it to get it at its purest.


 * Journal 8, Experiment 8, Day 6**
 * Hypothesis- ﻿By distilling our homozygous mixture, it will make our water drinkable and pure. **


 * <span style="font-family: Tahoma,sans-serif; font-weight: normal; line-height: normal;">1. Requirements- Glassware, clear water, and bunsen burner **
 * <span style="font-family: Tahoma,sans-serif; font-weight: normal; line-height: normal;">2. Set up glassware **
 * <span style="font-family: Tahoma,sans-serif; font-weight: normal; line-height: normal;">3. Boiled clear water **
 * <span style="font-family: Tahoma,sans-serif; font-weight: normal; line-height: normal;">4. Let boiling water evaporate into the glassware on the other side of the tube. **
 * Before After**
 * Water after our eighth attempt-** This basically boiled our water to distill and purify it. We now have our water as a pure compound.
