Water: A Portfolio of Student Learning

 1.  Using your water log (and average water use from the days you logged), calculate what your average water use per year might be.  219,000 a year 2. What is your estimated water footprint as found using the water calculator on www.waterfootprint.org? (Express in both cubic meters per year and liters per year)   Does this surprise you in any way? Why?2879 cubic meter per year. 2,879,000 liters per year. This surprised me because i didnt know i use this much. I also learned that 1 humburger uses more that 1000 gallons of water because they have to water the plants so the cows can eat it and then when there big, we kill them to make hamburgers. Some farms only need 100 gallon because of the rain water.3. Think about your average per year from #1 and your estimated water footprint from #2.  Which one is greater?  Why?  How big an impact does “hidden” water use seem to have on your overall water use?  Footprint #2 is greater. This is greater because of all the other hidden water use. In my #1 i didnt know it was hidden because i didn't know and i didnt learn about it yet. 4. How does your water footprint compare with the average footprint of the USA?  Why do you think this is so? Mine and the use more than 2000 cubic meters. We get water really fast(turning on the drain) so we miss use it...and we can use it anytime because it cames to us and we don't have to walk 10 miles just to get a bucket of water.5.How does the average USA water footprint per person compare with that of other countries around the world?  Why do you think such differences exist?  Well in china the water isnt as clean as USA. They have to boil it which might cost a lot of money. So china won't waste good fresh water. 6. How does your water footprint - and that of every human on earth - play a role in the water cycle?  What positive or negative Biosphere <-> Hydrosphere connections might be created by our individual water footprints? Every human "pees" so it means that it will soon evaporates back into rain.(posititive)We waste our fresh water and sooner or later we wont have any left. (negative) All the earths water will turn into sait and dirty which we can't or we get sick and the sait water isn't drink able because of all the sait.
