Problem+Requirements

You have a sample of water from the pond in front of you. Your group will receive no more supplies of the foul water for the remainder of the project so use it wisely. You must find a way to survive. In addition, your group has decided that should you not survive, you will prepare a journal (Google Groups Discussions - one for each day labeled with the date) outlining your attempts at purifying the water. You considered the possibility that the other group who left the island may end up returning after your group has expired or been rescued. You felt it important to document for them the experiments you had attempted and the results lest they waste time trying to redo the same things you already tried. Interestingly, the other group of 4 who left the island are from France and have no idea whatsoever of the English system of units that you are accustomed to. Your experiment journal must have units converted to the metric system to be of any use to them. Your group must then use the standard format of writing a lab report (We will go over this shortly). In this journal, you must use (in the correct context), the following scientific information: **1. Heterogeneous vs. Homogeneous Mixtures** **2. Element vs. Compound** **3. Pure Substance vs. Mixture** **4. Density** **5. Separations** **6. Distillation** **7. Accuracy and Precision** **Experiments**: From now until the end of next week, please bring appropriate footwear as you may work in a lab setting on any given day.
 * Will You Survive – Requirements**

**__Your group is responsible for:__** Your decisions on alterations to your water purification process can be based on results you observe from others and is encouraged. However, should the teacher question you about your ideas, **YOU MUST** be able to reference where on the Google Group site you got the idea. Suggesting that someone ‘told’ you will not suffice and your group will lose points. You will have to time (using a stopwatch) your procedure and measure how much foul water you recover for each experiment (Starting with 100mL). Within 24 hours of each experiment, a rough copy (bullet point form is OK) of the experiment must be found on your own group’s Google Group site. I will be checking randomly each day for this. Make sure it is done.
 * 1) Updating your Google Groups site every day with your experimental procedures for that day, what worked/didn't work, and what you will try next based on current results. DO THIS IN THE DISCUSSIONS AREA! This is going to be VERY helpful when you need to write your report. You can do this in bullet point form, but you need to add enough detail such that you could run the experiment again. I will be checking randomly each day for this. Make sure it is done.
 * 2) Taking pictures of each experimental set-up and of your results. You should label these with the date and experiment number so you don't confuse them. After a while, you may have a lot of these.
 * 3) A report using proper jargon on the scientific information above (#1-7) including pictures of your final experimental design. Format for this to follow . ANOTHER GROUP WILL RUN YOUR EXPERIMENT AT THE END TO CONFIRM WHETHER IT WORKS (THE FOUR THAT RETURN ON THE RAFT).
 * 4) Updating a future site with your information so you can see what other groups are doing (once we can see files and not get "Access Denied").
