This week is when Lauren and I will be measuring the different levels of things in the water such as ph, salinity, and the water quality. The supply's should arrive tomorrow, so we will have the tools to do the project. We are planning on using oil of oregano, membrane filters and charcoal. We are also going to use a common method where you use the heat of the sun to evaporate the water leaving salt and other particles behind. Thats where the remaining cleaner water is filtered through the oil, membrane filter paper and charcoal. Then, we will test the clean water and compare it to it's original results to see improvement in the water quality. We're going to try a few different combinations to see which one works the best and if there is anything else that can be improved on.

This week lauren and I have been working on our checkpoint assignment. It is due on tuesday and it is simply a checkpoint where we describe what we have accomplished so far and what we have failed at and we have to list our short term and long term goals. My short term goals are to test the water within the next week, and to find more ingredients that will work for removing bacteria such as vinegar and other more acidic ph's

Yesterday, Lauren and I finally did our experiment! We started off with dirty and salty brown pond water and then we used the membrane filters and our selected ingredients to filter out the salt and some of the dirt. We first tried out the chia seeds. The chia seeds seemed to absorb a lot of the dirt making the overall water much clearer. After that we tried pineapple, then potatoes, the yogurt, and coconut oil. The pineapple and potatoes seemed to do fairly well and the coconut oil collected much of the visible dirt particles but the yogurt was too watery and did absolutely nothing. After that Lauren and I took some samples of the chia seeds water before and after filtering. We did not yet take samples of the other ingredients. We have just ordered PH/ Water quality/ Salinity tester off of Amazon so as soon as that arrives we will be able to check out the results much more precisely and we will be able to re evaluate the other ingredients. I think our project is doing well so far and I'm ready to see which ingredients help to most.
