Presenter Robert Winston describes the process of ovulation in humans. At about day 14 of the menstrual cycle, the mature egg cell is released from the ovary. This is called ovulation. The clip also includes video footage of the moment ovulation and the egg's journey along the fallopian tube.
Sexual reproduction in humans could be compared to that of other organisms and to asexual reproduction. Encourage the class to research and discuss different methods and relate these to success rates and species survival. Students may find it useful to create flow diagrams that describe the different processes that have to occur for each type of reproduction to succeed. This should inform their comparisons.
