6.6.A5  William Harvey’s investigation of sexual reproduction in deer.

• Outline Harvey's methods of studying reproduction.

• State Harvey's discovery about reproduction. 

6.6.NOS  Developments in scientific research follow improvements in apparatus- William Harvey was hampered in his observational research into reproduction by lack of equipment. The microscope was invented 17 years after his death.

Describe what Harvey was and was not able to observe in his reproduction research given the tools available at the time.
