14. New Information for Task 3
Galvani and Volta were pioneers in electricity they discovered volts and current

15. Task 3: (Level 7) Task 3: Read each extract and complete the table
Task 3: Extension
Are their any aspects of Volta’s and Galvani’s
research that oppose each other?
Would Volta’s invention of the first battery have been
possible without the work of Galvani? Don’t forget to
explain your answer.
