Title of your project

Abstract:

Part 1: Simply write out the question “Which of the two elements is the biggest pollution threat when dissolved in water?”  Be sure to include the names of your two elements.

 

 

Part 2:  Write the names of books or Internet sources that you used in your research.

 

 

Part 3:  Which element was the greatest threat for each of the 7 characteristics?

 

 

Part 4:  Overall, which element is the biggest threat?

 

 

Introduction:

Part 1:  Give the dictionary definition of each of the seven characteristics you are using.

 

 

 

 

Part 2:  Background information about your two elements.

 

 

 

 

Part 3:  Restate, in greater detail, the problem:  Discuss such things as how important water is to our lives, how we use it, and how pollutants like the two you are comparing can threaten our water supply.

 

 

 

 

Part 4:  How will you convince the reader that your conclusion in selecting the worst element is correct: show your comparison matrix, library research, Internet search, and discussion section.

Results:

Part 1:  A neat comparison matrix with simple, visual comparison between the two elements.  Use terms like very low, low, medium, high, very high, plus, minus, or numbers.  If you have more than two words per box, you have done something wrong.  Remember, you must have two anions for both of your assigned elements.  Keep in mind that there can be no ties in your comparison matrix.  One element must be at least a tiny bit more of a threat for each characteristic.  Indicate this element on your matrix under the “biggest threat.”

Characteristics	Metal	Metal+ anion	Metal+ anion2	Metal2	Metal2+ anion	Metal+ anion2	Worst
Solubility	40g/100g
Melting point	X0	X0	X0	X0	X0	X0	X
Toxicity
Common uses
Carcinogenic	yes	Very	no	Maybe	Very	no
Corrosive	yes	Very	no	yes	Very	no
Abundant	yes	Very	no	yes	Very	no

 

 

Part 2: You must draw the water cycle.  Included in this diagram show where your two elements and their two compounds could enter the water cycle.  In other words, show where all six could get into our water supply, into your drinking water.  Also include any other visuals that helped you to decide which element is the bigger threat to you health if found in your drinking water.    The key is having visuals that relate your elements to water.

 

Discussion/Conclusion:

Part 1:  Describe how each element, both alone and combined, rates of each of the seven characteristics you used.  For instance, were they all high, all low, or were some much higher than others.   Were there big differences or were they very similar?  Be sure to include information about the combined forms of your elements in this section of your report.  This is the longest part of the project, so use as much detail as you can.

Part 2:  Which is the bigger threat based on what you explained in part 1?
