    Hi British School kids. Your project looks very well put together and had a lot of useful information.

    I really enjoyed this video. I was glad that you mentioned that challenges and what you would do to improve your project. I also like that you all individually explained how you contributed to the project. However, some of your faces were cut off and sometimes it was difficult to hear you. Overall, great job guys. I liked all your pictures, too.

    It was mentioned that an issue with the filtration process was that the rocks used were not clean. I am confused as to if these filtration processes were meant for people camping in the wilderness or for everyday people, because are not all rocks a bit dusty? Also, out of the three different filtration processes tried which one was the most effective. Other than that it would be very interesting to see of you shared your information with your community, which would inform people on different types of filtration, and hopefully become helpful to those who do not have clean water. To go even one step further you guys could possibly hand out filters you made to people in your community.

    The topic for this group 4 project was chosen very well as clean water is becoming harder to obtain in the world. While some countries have means of large scale filtration, others still suffer from the effects of drinking contaminated water. The item created in this project could be used as a cheap and effective tool to allow filtered water to become more widely available.

    Did you test to see if the ph changed during chemical filtration due to the chlorine tablets? If ph did change (altering change in taste of the water) is there a way to prevent ph changes in the water to maintain a normal ph?
