This 17-slide Powerpoint show describes the period known as the Great Leap Forward for humanity. Slides do not contain an overwhelming amount of text and the language is very straightforward.
The acronym 'tya' in the show stands for 'thousand years ago' (i.e. 35 tya means 35 000 years ago). Similarly, the acronym 'mya' stands for 'million years ago.'
The show includes images to help students visualize some of the concepts that are addressed.
If you teach in Ontario, this slideshow fits nicely into the CHW3M course.
