Day 1: Today we worked on developing new plans and brainstorming our ideas of how we were going to filter the water. We came up with several theories including filtering the water through a tube filled with charcoal tomorrow we will go over some more plans an begin our experiment to clean the water.

Day 2: Today we continued going over our plans and because of our period being cut short we were not able to get much done but, we went over several ways to handle the experiment including using filter paper with a funnel and then putting the water into the tube with the charcoal to get some of the smaller items out of the water.

Day 3: Today we began our experiments our first experiment we just tried to filtered it through the charcoal in the tube. The experiment did not go as planned as our water turned black because of the experiment, so then we went back to the drawing board and came up with a new plan, to use a funnel and put a filter, gravel, and sand in the funnel and then pour the water through the funnel and let the water be filtered. We began to set up the experiment but time stopped us short so we were unable to finish the experiment.

Day 4: Today we got into class then right into setting up our experiment and we got started right away. We began the experiment, the water did get clearer but not to the point at which we needed it on so we then decided to use charcoal, sand, and gravel through the funnel and again it got clear but there was still yellowish water and some sand fell through. We felt because the water was getting clearer so we continued to use the funnel and filter technique. We still had some time in class so we tried one more experiment by using gravel and charcoal and we filtered it again, but we still had the same results so we started thinking over what should we do now. Class ended and so we had to wait till tomorrow.

Day 5: Today came in and decided to try one more funnel and filter experiment by using sand and charcoal and when it was filtered it was very clear, but not all the way. We all decided because that had filtered so well we should try it again. We then put the sand and charcoal in then we mixed the two together so it was a blend of both sand and charcoal. When we finished mixing we poured water through and it was clear. After much experimentation we finally got the water clear. We also realized though in this process the water must be filtered several times before it is mostly clear. The same day we came up with a way to get all of the bacteria and the rest of the things in the water out. We wanted to heat the water and have it go to a tube and the tube would pour out the water the problem was how are we going to do that. Class then ended so we would have to figure this out tomorrow.

Day 6: Today we were thinking of how we were going to do this and then we figured it out we had to boil the water and use a special double tube that changes the boiled water back into a liquid. It works because on the outer tube there is cold water and when this steam goes through the tube the steam turns back into the water. We then worked on smaller things of the project like finding out some of the densities of the oiled water.

Day 7: Today we began with removing the bacteria from the water by heating it using a set of tubes that turns the water into steam and then back into water. We then heated the water and about 5-10 minutes later the water was boiling and moving into the second tube and then turned into water and dropped into the last Becker. The rest of the time I took pictures, we read over the rubric, and began our lab report.

Day 8: Today we continued our lab report and I began transferring info from Google groups into the Wikispaces Survivor Group. We went back to the water and looked at it but it was still unclear weather the water was clear of all the types of bacteria.

Day 9: Today we came in and used a battery and a light bulb to check weather all of the bacteria in the water was gone. The light did not light up so that meant all of it was gone. When you looked in the flask that you originally boiled the water in there was a yellowish grime molded onto the bottom of the flask.

Day 10: Today we worked on our lab report and continued to work on the lab report.

Day 11: Today was the last day and we finished working on the lab report and the wikispaces.
