Topic 9 and 19 - Redox reactions

Activity 1 - Animal electricity

Subtopic 9.2 - Electrochemical cells
NOS statement 1.5 - Many scientific discoveries have come from speculation or simple curiosity about particular phenomena. 
Time: 5 min.
Task: Answer the following questions:
  1. What was Galvani originally investigating before discovering the "Galvanic" (or "Voltaic") cell?
  2. How did Volta build upon this discovery to create a useful application?
  3. What is animal electricity?

Activity 2 - Who cares?

Subtopic 9.2/19.1 - Electrochemical cells
NOS statement 4.7 - Scientists often work in areas, or produce finding, that have significant ethical and political implications.
Time: 15 mins.
Task: The development of fuel cells has far reaching implications in environmental, health, economic and political issues. Note down as many links as you can between the photos below that relate to the NOS statement above.
