Activity adapted from Upd8 website. I have included the original adobe file although I only use page 2 (information cards). Pupils are given the student instruction sheet and read a news article about how caffiene can increase the motility of sperm (original article from new scientist). They then use the information and cards (adobe file page 2) to draw cartoons to show how the sperm will move in different semen samples (coffee drinkers, cannabis smokers, overweight men and a 'normal' man). I have inlcuded the cartoon template as I set this as a cover lesson and wanted to make it as easy to follow as possible, but they could just do this in their books.
