2012+SUMMER+B

=Please complete the following by August 6th.=

Part 1: Read Chapters 3 and 4 in your Zumdahl Chemistry text.

Part 2: Visit [|Science Geek] again, and complete all activities for chapters 3 and 4. . Please keep track of all problems by writing down the problem and your solution in a notebook. I will ask to see this when you return in September.

Part 3: Please open the link[| Urban Farming Story] and read the article. While you are reading, please pay careful attention to the discussion on chemistry (nitrogen, ratios, etc.) Then, please do some follow up research into the relationship between nutrient ratios and how plants grow. This is an aspect of chemical stoichiometry which is not generally taught in high school, but is crucial to the production of food and the world's economy as well. If you don't remember what stoichiometry is, do some research do re-learn that also.

Finally, I am asking you to write a 2-3 page paper on the relationship between stoichiometry (ratios of elements) and farming. You can go in any direction you want. I suggest you research these folks as part of your assignment:

Justus von Liebig David Tilman James Elser and Robert Sterner

All of your references must be included in a works sited section. I don't include this is the page limit, it's additional. You will not get credit for the assignment without at least 5 separate references. These can all be internet sources if you are working well that way.

Please upload your REPORT ONLY to this page using the following file format: SummerB_Interlandi (use your own name). If for some reason you don't have MS Word, please be sure to save your file in TEXT format before you upload. It is nearly impossible for me to read those wps files!!

Please feel free to e-mail me with questions, and for goodness sake, use the discussion board here to share thoughts and ideas with your classmates!! BettyNyarkoAP Chemistry.docx
