Webquest Part 8
Select three of the following examples of invasive species:
Brown tree snake in Guam
Nile perch in Lake Victoria
Sea lamprey in the Great Lakes
European Rabbit in Australia
North American gray squirrels in Europe
Mallard ducks in Hawaii
Ornamental fig trees in Miami
Water hyacinth plants in Florida
Asian mongooses in Hawaii
Zebra mussels in North America
Dromedary camels in Australia
Comb jellyfish (ctenophores) in the Black Sea
Piranhas in the United States
In your presentation or report, answer the following questions for each. (1 point for each answer about each species; 3 points for each question; 21 points total)
1: Was the introduction intentional or accidental?
2: How did it happen?
3: Why did the organism do well in the new environment?
4: What was the effect on the native environment?
5: What efforts have been made to eliminate or reduce the numbers of the organism?
6: What is the status right now of the organism in the new environment (has it been eliminated, or does it still flourish)?
7: Include a picture of the organism.

ELECTROCHEMICAL FUNDAMENTS
As you know, copper ions are related to a Transition's Metal.
This relation is based on an electrochemical trendy obeying to an electromotive force leading this phenomenon.
W. H. Nernst collected the "Electrochemical potential at Standard Conditions" that is he dipped a metallic copper rod in a 1 M copper ion's aqueous solution : this system is a "First Electrode Type" and it may form a Voltaic Pile when it is connected to a S.H.E. Electrode. The latter is formed by a platinum's sponge dipped in a 1 M hydrochloric acid's aqueous solution receiving a gas-stream of hydrogen bubbles flowing at 1 atm.
Nernst measured a "E.M.F." like 0.34 V ; he assigned 0.00 V to S.H.E.'s system, hence the Copper's Electrode receive the Standard Electrical Potential as E° = +0.34 V, meaning that Copper's Electrode is MORE NOBLE than S.H.E.'s ones.
You may change this experiment if you dipp the metallic copper rod in a 1 M POTASSIUM IODIDE's aqueous solution instead copper ion's one. You may measure an "E.M.F." like 0.19 V ; Nernst assigned 0.00 V to S.H.E.'s Electrode, hence the NEW COPPER's ELECTRODE have a Standard Electrical Potential as E° = -0.19 V, meaning the NEW Electrode results LEAST NOBLE than S.H.E.'s one.
